How To Change A Wheel On A Bicycle

How to replace a wheel yourself. step by step instructions

Therefore, this article is primarily intended for people who want to learn how to replace a wheel on their own at home, that is, with their own hands. Today I will try to tell you in as much detail as possible about this seemingly simple procedure, and who knows, maybe this article will become for someone a kind of step-by-step instruction on how to replace a wheel or wheels.

So, if you are faced with the need to replace a wheel with your own hands (no matter where on the road or at home), you should, first of all, follow all safety rules and most importantly do not harm yourself and the car. Negligence in carrying out this work can lead to injury, as well as damage to the vehicle. Let’s get started?

The order of work is as follows:

Make sure the car is standing “on the handbrake”, in addition, it does not hurt to turn on the first gear, as they say for insurance.

Next, place wheel chocks or pieces of brick under the wheels (those that will not be replaced); blade-shaped logs are also suitable. The blades should be hammered tightly, it is not forbidden to use a hammer, with its help it will be easier to send the safety wedges as deep as possible.

Further, in order to make wheel replacement easier, before lifting the car with a jack, you must loosen the nuts of the wheel you want to replace.

Further, in order to replace a wheel that is out of order, prepare a “spare tire”, put it near the car, just put it against the car in no case. First, it will most likely roll or just make a few new scratches on your car.

The next step is to lift the car with a jack. Attention! I want to warn you so that you do not repeat the mistake of many “newbies”, whose wheel change ends with a trip to a straightener or service station. When installing the jack, you need to make sure that its upper point rests against the socket specially designated for this, otherwise damage and repair of the threshold will be provided to you. It is necessary to jack up until the wheel to be replaced is in the air.

Now unscrew completely in advance “ripped off” nuts and completely remove the wheel.

Install a new wheel (spare wheel) and carefully secure it with nuts. Be careful, use medium force so that God forbid you do not push the car off the jack. If necessary, tightening can be done after the car is removed from the jack.

The wheel replacement procedure is nearing completion, it remains to lower the car and tighten all wheel nuts.

Put the dismantled wheel in the place where the spare wheel was lying, but if you are at home, then just remove the wheel in a place where it will not interfere with you.

Now you can remove the wedges and after checking the tire pressure with a pressure gauge, you can continue your movement.

Well, that’s all, I hope that from now on it will not be a problem for you to replace the wheel yourself. It doesn’t matter when the knowledge gained today will be useful to you, it is important that now you can easily find a solution to the current situation.

How to change the rear wheel on a bike

Removing the wheels from the frame is part of a mandatory bike maintenance procedure. Sooner or later, the wheel of even the most advanced bike will present surprises in the form of deformation of the rim, damage to the spokes, a burst tube or even the entire tire, as well as wear of the sprocket system for the rear wheel.

Experienced cyclists welcome self-repair of wheels, and it is no coincidence: it’s cheaper, and you can acquire skills. You can also go to a good workshop, where the problem will be solved, perhaps faster, but not free of charge. over, the service is hardly located under the windows of the house, so the bike will have to be dragged, which is not very pleasant. To avoid this, it is better to tinker a little yourself, especially since there is nothing complicated about the wheels. Today we’ll talk about how to remove the rear wheel from the bike, repair it and assemble it correctly.

When to remove the rear wheel

It is unlikely that the idea of ​​unscrewing the chassis from the bicycle frame would just come to mind, unless, of course, a person specializes in bicycle dismantling. But this is a completely different case. Dismantling the rear wheel will be required if the following problems are observed:

This also includes the planned replacement of the rear sprocket system and chain.

Usually, one wrench of the appropriate size is enough, with which the nuts are removed one by one. If the hub axle turns, then the nuts are unscrewed simultaneously in different directions. Open-end or box wrenches are recommended. The adjustable version is undesirable, as its thick horns “eat up” the corners of the nut due to loose fit and sliding.

Replacing the bike camera

To remove the tire and remove the damaged chamber, it is necessary to remove the remaining air: the cap is unscrewed and the wheel is lowered by continuous pressing on the nipple. If there is no air in the tire, which often happens with punctures, then simply unscrew the cap.

To remove the tire, you will need special paddles. Of course, you can pry the camera with a regular screwdriver and even a knife, but it is better to have a professional tool. With the help of assemblies, the tire is pushed on from the side opposite to the nipple. As soon as it starts to pull together, you need to pry the beads a little further, until a sufficiently free part of the tire is formed, and it can be safely pulled off the rim.

Before removing the bike, turn it over and place it on the saddle and handlebars. It is better to remove awnings in the form of a mirror, bell and lantern in advance so as not to damage them under the weight of the frame. V-brakes are first released and removed, otherwise they will not allow the wheel to be pulled out freely. With disc models, everything is easier. you can immediately remove the wheel.

I must say that the removal process itself consists only in unscrewing the eccentric or unscrewing the fastening nuts from the axis of the bushing, who has something. If the mount is an eccentric, simply unscrew the handles and twist the wheel. The nut fastening is loosened with one or two keys.

Usually, one wrench of the appropriate size is enough, with which the nuts are removed one by one. If the hub axle turns, then the nuts are unscrewed simultaneously in different directions. Open-end or box wrenches are recommended. The adjustable version is undesirable, as its thick horns “eat up” the corners of the nut due to loose fit and sliding.

As soon as it starts to pull together, you need to pry the beads a little further, until a sufficiently free part of the tire is formed, and it can be safely pulled off the rim.

You need to tighten very carefully so as not to damage the rim, do not use too much force. When the tire is removed, remove the damaged camera and install a new one. The nipple is threaded into the hole in the rim, then the chamber is evenly distributed around the circumference.

On top of the rim, the outer part of the tire is put on, this time, from the side of the nipple. When installing a tire, take into account the correct direction of the tread pattern. Usually, arrows are drawn on the tires, and in the upside down state of the bicycle, the forward direction is backward in the lower position. The rear wheel of a speed mountain bike is easy to go wrong, though, thanks to the cassette on the side. After mounting, the camera is inflated.

Removing the cassette and bulkhead bushing

A hub is one part of a bicycle wheel that requires periodic maintenance. On average, you need to look into it once every 2000 km of run, in terms of time it is 2-3 months of active driving. If the wheel is already creaking and there is a decrease in the efficiency of rotation, in other words, the great rides worse, then it is time to remove it and inspect the hub.

The main problems with the bushing are backlash and insufficient lubrication of the bearings. Due to a violation of the fit or increased friction, parts begin to wear out rapidly. If the wheel has not been serviced for a long time, the bearings may crumble altogether. To gain access to the hub bearings, you will need to temporarily get rid of the rear sprockets.

The reverse gear is removed with a puller and a so-called whip. Removing the cassette is not a long matter, but you will have to make a lot of effort to unscrew it from the wheel. In stages it looks like this:

  • The stripper is inserted into the cassette nut.
  • The whip holds the large star of the system so that it does not turn.
  • With a wrench, the puller rotates, unscrewing the slotted nut.
  • We remove the small stars that are installed on top, carefully fold them to the side along with the washers, and then remove the cassette itself.

Before disassembling the hub, loosen the spoke tension slightly. This can be done using a round key with knocked out holes for different diameters of the needles. You need to loosen up a little, a quarter of a revolution is enough. If the sleeve needs to be replaced, then the spokes must be unscrewed enough to easily pull it out of the engagement.

A complete bushing replacement is required if both the axle and the bearings become unusable. However, often when the bushing is jammed, the axle is in normal condition, it is enough to change the bearings. Often, both will still serve faithfully if they are well lubricated. Proper lubrication will prevent parts from wearing out under dynamic loads.

Speed ​​bike rear hub diagram

The bulkhead of the axle part of the wheel is associated with cleaning the axle and bearing balls from dirt. The removed parts must be temporarily placed in a solvent, then allowed to dry, lubricated and reinstalled. Bearings in a skewed position must be adjusted by returning them to a straight position. However, during the backlash, the parts are already faulty, so replacement is the best option.

Assembling and installing the rear wheel on the bike

A quality wheel repair is not only about disassembly, replacement, lubrication or adjustment. At the last stage, all this chaos must be collected in reverse order. All parts of the bushing mechanism are placed in the drum and carefully secured with locknuts. The drum is pushed onto the spokes, after which they must be tightened by the number of revolutions by which they were loosened.

Tightening the spoke nuts is done in the opposite direction to loosening. Here you need to remember the direction of loosening in order to tighten correctly. If the drum dangles, then you need to tighten the spokes harder.

The cassette is put on the sleeve in this order:

  • main stars;
  • single stars, small stars;
  • whip tightening the cassette mechanism.

All that remains is to put the rear wheel on the frame. A chain is put on one of the stars, and the wheel is inserted into the grooves of the frame. To top it off, all that remains is to tighten the nuts or eccentrics on both sides. After assembly, you need to twist the pedals and see if the chain runs normally in the stars. We turn the bike over and begin to ride calmly!

Anyone who actively rides a bicycle will have to deal with wheel problems one way or another. Despite the ease of maintenance, the wheel can be time-consuming at first. However, if you remember how important wheels are for a bicycle, it turns out to be not so much. What’s more, with experience, a wheel bulkhead will take minutes.

Bicycle rear hub and its device

One of the important parts of a bicycle is its wheel. In particular, the rear wheel is much more loaded than the front wheel, since it is on it that the ratchet (freewheel mechanism) and the cassette (sprocket block) are installed. The wheel is the main focus when driving, so it is important to understand the design of its hub in order to be able to properly maintain it.

A hub is an element of a wheel that is attached to a bicycle frame, namely drop points. This is the central part of the wheel, allowing it to rotate freely.

The bushing consists of such elements as:

  • Axis.
  • Lock-nut.
  • Washer.
  • Cone.

Varieties of rear bicycle hubs, how they differ from each other

One of the reasons for dividing rear hubs into varieties is their design. Depending on it, the rear hubs are divided into:

  • Without brake.
  • With built-in brakes.

It should be said that bushings that are not equipped with a brake mechanism are also divided into those without free play and with free play. With an integrated foot brake, the hubs are designed with free play. If we are talking about a hub with a brake mechanism, then their main feature is that the pedals must be pressed in the opposite direction to stop the bike.

According to the method of fixing, the bushings can be fixed on two nuts, which is much cheaper, or can be fixed with an eccentric. The second method is more expensive, but much more convenient, since the nuts need to be removed with a wrench, and to remove the wheel on the eccentric, it is enough to squeeze its handle. It only takes a couple of seconds.

The material of manufacture also matters. Bushings are:

  • Aluminum (lightweight and non-corrosive).
  • Steel (strong but heavy and highly corrosive).

The bushings also differ in the size of the axle, the standards are different. from 9mm to 15mm. Keep in mind that the larger the sleeve, the heavier it is.

When to service the rear hub

For the correct operation of the wheel and its main parts, incl. bushings, it must be kept in good condition at all times. It needs lubrication, and its body needs to be tightened periodically. In addition, replacing the bearing balls and adjusting the pads on the brake sleeve will not interfere.

Rear hub service is essential as in cases where this does not occur, the entire wheel may need to be repaired. Therefore, it is better to take care of your bike in the long run. It should be noted that servicing the rear hub is not much more difficult than the front hub.

It is necessary to perform maintenance in such cases:

  • If you hear body noise when the bike is moving or rocking.
  • Backlash.
  • If the bearings crunch.
  • Poor rolling dynamics.

If you do not pay attention to the above signs of “illness” of your bike and use it for a long time if available, it can quickly fail.

Repair, in turn, will be much more expensive than simple wheel maintenance, which you can do yourself. Therefore, at the beginning of each season, check the wheel for looseness and that the bearings are not too tight.

Housing disassembly, cleaning and lubrication

Before proceeding with the disassembly of the case, it is necessary to clean the workplace, since it is very important to carry out all stages very carefully and with utmost care.

First, remove the cassette from the axle using a puller and a whip. Then we open the retaining ring and remove the washers and bearings. In order not to get confused in details, it is important to remember the original location of the washers and bearings.

How to assemble a rear bike hub?

After lubrication, the sleeve must be reassembled. To properly assemble the rear hub, you must adhere to the following rules:

  • We insert the axis so as not to confuse which side is the right side of the axis, which is fixed tightly. The axis is adjusted with the left cone.
  • Next, put the left cone on the axle until it stops.
  • We put on the washers.
  • We screw on the lock nut.
  • Adjusting the bearings.

Rear wheel hub repair. Step-by-step instruction

  • Checking the workplace. We clean the workplace of unnecessary tools, things that are not useful to you.
  • Remove the retaining ring.
  • Remove the hub axle. First, we remove all the parts that are on the opposite side of the stars.

Most often, the repair of the rear wheel hub is necessary either with backlash or when tightening the cone. So, step by step instructions:

  • Checking the workplace. We clean the workplace of unnecessary tools, things that are not useful to you.
  • Loosen the lock nut with a wrench.
  • Loosen or tighten the flare nut.
  • Tighten the locknut into place.

If the cause of the breakdown is a malfunction or breakdown of any part, then you should simply replace it using the following recommendations:

  • After checking the workplace, remove the retaining ring.
  • Remove the hub axle. First, we remove all the parts that are on the opposite side of the stars.
  • Checking details for faults.
  • We replace the broken part.
  • We put all the parts in place, tighten the flare nuts and the locknut.

Causes of breakdowns

Bicycle wheel breakage occurs for various reasons. There can be a large number of them.

The main ones are:

  • Insufficient or no bushing maintenance.
  • Loose bushing (backlash).
  • Poor bushing parts.
  • Wear.
  • Padding the cone.

Thus, to ensure the long life of your bike, you should devote a certain amount of time to it. The basis of a bike’s long-term service is maintenance. You can do this yourself, with your own hands. The main thing in this is to observe safety precautions and carefully approach the matter, since every detail is important in the hub mechanism.

To service the bushing, it is necessary to remove all parts, lubricate, first removing all old grease. Then carefully re-install all parts in the reverse order. In this case, you should carefully consider the tightening of the locknuts and flare nut so as not to overtighten them. In addition, there are different types of rear hubs.

The main components of the wheel

A standard bicycle wheel consists of several main parts:

  • bushing. the central part, due to which the torque is provided. The interior of the rear hub is slightly more complex than the front. Not every bushing can be disassembled at home, some variations without special equipment and knowledge are better left untouched. And also brakes can be attached to this part;
  • spokes connecting the hub to the rim;
  • the rim on which the tire is mounted;
  • tire.

So, if the rear wheel of a bicycle needs to be repaired, or if it’s just time to service the spare parts, it is necessary to clarify the procedure that should be taken when removing the wheel.

Dismantling sequence

First, remove all unnecessary items from the bike that may be on it. And it is also better to unscrew all kinds of mirrors, flashlights and other little things that can be damaged during work.

  • We turn the bike upside down, put it on the handlebar and seat. You can do without a special rack for repairing a bicycle, the main thing is to give it a stable position.
  • We find out the type of brakes installed for further action. As usual, these are disc or rim brakes:
  • disc brake. It will be easier to remove the wheel with it;
  • The rim brake of the V-brake type must first be released and removed, otherwise further dismantling of the wheel will no longer be possible. (It is not difficult to release the brakes, for this you need to move the cable to the side of the fastening screw, move the levers, removing the end of the cable from the clamp, lower it down and spread the brake levers to the sides).
  • Next, we act depending on the type of attachment of the rear wheel to the bicycle axle. We unscrew the nuts with a wrench (one or two) or, if the mount is a disc eccentric, unscrew the brake lever and twist the wheel.
  • The chain passing through the gearshift system is carefully removed from the sprockets.

The wheel is removed. Now you can carry out all the necessary further manipulations: replacement, adjustment, lubrication of parts.

Camera replacement

First of all, you need to lower the wheel. unscrew the cap and release the air by pressing the nipple. If the chamber is damaged and there is no air in it, simply remove the cap. To remove the tire, you will need mounting paddles, with which it will be convenient to pry the tube until it becomes easy to pull it off the rim.

The camera can be replaced without the need for tools. First, the nipple is inserted into the hole in the rim, after which the tire is evenly put on the rim. Finally, the camera needs to be pumped up to the desired state.

Removing the sleeve

We remove the cassette with asterisks using a special puller, a key and a whip. First, we insert the puller into the nut, then insert the key into it, put on the whip on the large asterisk, hold the asterisks with it, and unscrew the nut. Now that the nut is unscrewed, you can easily reach the cassette with stars.

Before disassembling the hub, the tension on the spokes should be loosened so that it can easily be pulled out of the engagement. When parsing this part, it is better to decompose all of its components in order, so that later you can precisely put everything in place. If necessary, you can replace the bearings, which, unlike metal components, are the first to fail. Timely service of the bushing will ensure its long service life, so do not neglect cleaning and lubricating the mechanism parts.

In the reverse order, the spokes are tightened exactly as far as they have been loosened, it is important not to overtighten them, but the parts must be firmly fixed. The cassette is put on the sleeve and tightened with a whip.

After all the procedures performed, due to which the wheel and its parts were dismantled, you need to know how to assemble the rear wheel of the bike back.

Installing the rear wheel

In order to carry out the installation correctly, assemble everything in place should be clearly in the reverse order.

  • Place the chain on the smallest sprocket, insert the wheel onto the frame mount. In this case, it is important to make sure that the axle is fully inserted into the grooves of the frame.
  • We fasten nuts or eccentrics, they should be tightened well so that the wheel firmly sits on the frame.
  • If there are rim brakes, fasten them. Return to the previous position in strictly reverse order, otherwise the next trip may not end very well.

After the installation process, it is advisable to check the correctness of the actions performed by means of a short test drive to see how your bike will behave on the road after the updates.

Maintenance and diagnostics of the rear wheel is a mandatory procedure to maintain the health of the mechanisms.

How to change a wheel on a bike

Cycling frequency increases with the arrival of sunny days. But at the same time, unfortunately, the number of tire punctures is also increasing. If you are a cyclist, sooner or later you will have to face a tire repair or replacement. Find out from our article how to quickly and easily change a wheel on your bike.

Step-by-step instructions on how to change a wheel on a bicycle:

Unscrew the nuts that secure the wheel to the frame. If you cannot unscrew, use a special tool. Silicone grease or even vegetable oil will work. (Many modern bicycles do not have nuts. They have a quick release mechanism that can be easily loosened and removed from the wheel).

Loosen the brake if you have one on your bike as it will interfere with wheel removal. Different bikes have different braking systems, but you will probably be able to remove the brake cable from the connector on the brake lever. On some brake systems it is necessary to loosen the cable from the clamped position.

Pull out the wheel. To do this, you may need to disconnect the brake pads, and if you remove the rear wheel, you will need to remove the chain from the sprocket (shifting to lower gears will make it easier to remove the chain). The front wheel is slightly easier to remove.

Fully deflate the wheel by pressing the valve in the nipple. If the wheel has a French valve (presta valve), you need to unscrew the top of the stem to release the air. At this point, you also need to remove the retaining ring (if you have one on your bike), which is screwed to the rod and is flush with the rim.

Squeeze the tire and go all the way around the rim. Compression will help release the air. Also, by compressing the tire around the rim, it will be easier to remove.

To change the wheel, remove the camera

Swing the pump several times to fill the chamber with air. Examine the camera, find the hole through which the air passes. The best way to find the hole is to dip the camera in water. Bubbles in the water will tell you where the air is leaking.

Carefully check the inside of the tire around the entire perimeter; also inspect the rim for glass, nails, or any other object that could puncture the camera. Be careful when checking the tire to avoid injury from a nail or glass shard. If you find any sharp objects, such as a nail or a shard of glass, be sure to remove them with tongs or pliers. Adjust the rim tape to cover the protruding spokes.

Repair hole or replace tire / tube as needed. If you bought a new camera, unfold it, remove the plastic cap and retaining ring.

Place the new tube on the tire; make sure you don’t twist it. Then pump up the camera. If you pump up the tube, you can avoid pinching it when installing the tire on the rim.

Put on the tire on each side in turn. This process is not easy, however it is best not to use a spatula or screwdriver or similar, otherwise you risk puncturing a new camera. The direction of travel must be marked on the tire in order not to put on the tire backwards. Insert one side first, then loosen the partially inflated tube and slide on the other side.

Make sure the camera is seated correctly, that the screw is on the retaining ring. Inflate the tube slowly and carefully to make sure the tire is level and not pinched anywhere.

Remove the pump and hand tighten the French valve and retaining ring.

Now you can put the wheel in place.

Lock the brake pads and put the chain back in place if you removed the rear wheel.

To change a wheel on a bike safely, do not forget about safety measures:

  • Take care that there are no hot objects near the camera. Heat increases pressure inside the chamber, which could cause it to explode!
  • You can dust the tube with talcum powder before inflating the tube with air or placing it in the tire.

How to change a tire on a bicycle. How to change a wheel on a bicycle. Velobaggio

Punctures are quite common, especially if it’s time to change tires or if you’re not only riding on asphalt. Although on it you can find a lot of everything that can cause a puncture. Remember that you should never ride a flat tire. you will kill a tire and rim, and replacing them will cost several times more than replacing a camera. In addition, it is not at all difficult to glue the camera, which you will soon see.

First, make sure you actually puncture the wheel. To do this, pump it up and see if the nipple is leaking. If this is the case, tighten it tightly (it did not help. you will have to change the camera). Someone may say it’s easier to change right away, a new one costs only 50 rubles! But such a new one will be worse than the old one. A good bicycle camera costs from 200 rubles. By the way, the patch will cost you about 1 ruble! If the nipple is in order, and the wheel is deflated rather quickly and noisily, then it will not be difficult to determine by ear the place of the air outlet.

If the rear wheel is punctured, place the chain on the smallest sprocket at the back (to make it easier to assemble later). If your muantine bike has a v-brake, then you need to open it by bringing the brake levers together with your hand and removing the metal arcuate tip of the shirt from the groove, from which the cable comes out (see the picture). Then turn the bike over. It will be better to place rags under the steering wheel and under the seat so that nothing gets dirty or scratched. If the wheel is bolted, loosen with suitable wrenches. If it is attached normally, unscrew the eccentric, to do this, bend the lever and turn the nut on the opposite side (you can not completely unscrew it). And remove the wheel. The rear wheel can be removed more easily if you bend the rear derailleur tab so that the roller closest to the cassette stars does not press against them. You will see that if this is not done, the eccentric of the wheel hub will rest against just this place.

For the third, it will be enough just to pry off the tire, and it can be easily removed further with your hands. In extreme cases, small wrenches will go (see picture). Only they will have to be well held so that they do not hit on the forehead. You do not need to remove the other side of the bicycle tire, the camera can be easily obtained.

Pump up the camera so that it slightly increases in size and, pouring water into the sink, gradually scan the entire surface of the camera underwater for holes. The hole in the chamber will immediately be seen by a thin stream of bubbles coming from it. Having found one, do not rest on your laurels, check the entire chamber so that you do not have to do everything again.

A leaky chamber can appear not only from a puncture, but also from a breakdown. You can pierce the bike camera by bumping into a large pothole, rail or curb at speed. In this case, on the camera you will find not one, but two holes at once, in the form of short parallel cuts. Thus, you can easily have a figure eight on the wheel. To prevent this from happening, in addition to failing to perform the above actions, it will help to pump the wheels harder (3-4 atmospheres), but pay attention to the permissible maximum tire pressure, you cannot pump above it!

If the camera is punctured, then carefully inspect the tire at the puncture site to see if the perpetrator of the puncture remains. It can be glass, wire, self-tapping screw, or any other sharp and thin object. Don’t search with your finger! Otherwise, you run the risk of sticking not only the camera, but yourself. Take a spoon, for example, and run it over the inside of the tire. It will be easier to search if you notice at what distance from the nipple the hole and check the tire there. It is necessary to find the puncture site on the tire so that the camera does not turn out to be punctured by the same object again, standing in its place. If there is nothing in the hole, move on.

It so happened that the hole is not on the outside of the chamber, but on the inside. then inspect the rim. If your bike has single rims, it is possible that the tube has a punctured spoke. Make sure there is nothing sharp on the rim and that the flipper is intact (a special rubber band that covers the ends of the spokes on the rim). Replace the flipper if it is torn. It doesn’t break just like that, find what could break it on the rim and align it with a file. But this happens extremely rarely and is associated with a factory defect, which was not noticed when assembling the wheel.

It is best to use an old cycle tube to seal the hole. Cut out a small circle from it, 1.5-2 cm in diameter (if the hole is large or after punching 2 very close, then even 3 cm). But remember that the larger the patch, the worse it will hold. Sand the puncture site and patch with a fine sandpaper (the rougher the surface, the better it will adhere). It is more convenient to sand the patch before you cut it! Degrease the sanded surfaces with alcohol or vodka. It is convenient to do this with cotton swabs, because they leave no fibers. Do not blow to dry. exhaled moisture will impair adhesion. To make it easier to manipulate the patch and not touch its treated side, stick it on a piece of electrical tape or plaster (see the picture)

Now about what is better to glue. Of the instant adhesives, the best are Super Glue Extra (HI-TECHO), Super Attak Gel (German Loctite) and Super Moment Gel (Russian Era), but to glue them you need to have a certain skill. not to shift the glue and accurately apply the patch, press firmly and quickly. Only the patch should be smeared with second and instant adhesives. How to glue them is written in detail on the package. Use them when time is running out.

It is safer to use adhesives acting after 12 and 24 hours. Among the daily allowances, the best glue is “88-CA”, and “Master”, “Sprut” and “88-NT” are also quite good. Among those that dry in 12 hours there is an excellent glue “Radical”. But unfortunately, it is rarely possible to find something other than “Moment” in various variations, but it will do. With either of these adhesives, apply a thin, even layer to the patch and camera around the hole. On the camera, apply a spot of glue a couple of centimeters larger than the diameter of the patch. it will be easier to hit Some adhesives need to dry before pressing the glued surfaces, which is indicated on the package. And then put a patch on the hole (try to keep the hole under the center of the patch), cover it with a piece of paper on top (so that the paper sticks, not the press) and put it under the press. It is convenient, for example, to press the camera with a clamp to some flat surface (window sill, board).

And that’s it! After 12 or 24 hours (depending on the glue), try gently tearing off the patch. Holding on? Insert the tube back into the wheel, starting with the nipple. Tuck the tire into the rim, taking care not to get the tube between them. If you cannot fully refuel the tire, use a razor or an eccentric lever. Place the wheel on the bike, tighten the eccentric or gulls. If you have a v-brake, do not forget to close it so as not to be left without a brake, it may need to be adjusted. Inflate the wheel slightly and with your hands remember the tire well along the entire length so that the camera fits well. Now you can pump the wheel to the end.

There are many first aid kits with express camera patches on sale now. They cost almost all 100-150 rubles, in sets of 6 patches. Topeak TGP01 first aid kit is preferable in terms of reliability and ease of use.

If it so happens that you puncture the wheel, there is no spare chamber and there is nothing to seal it with, but you have to go and there is a pump, then pump up the wheel to 5 atmospheres. This high pressure will press the tube well against the tire, preventing air from escaping strongly from the hole, and will allow you to reach your destination. Don’t forget the main thing later,

that the camera is still full of holes Better to have a spare camera with you.

Enjoy your ride and fewer punctures! If you don’t want to look for and seal holes in the wheels, we recommend using Maxxis bicycle cameras, in our opinion, the most impenetrable and puncture-resistant of the entire range, but quite tangible in weight (the one in the picture weighs 300 g).

Replacing a tire on a bicycle. Velobaggio

All cyclists are constantly faced with the problem of changing tires on their bicycles. Of course, you can contact the workshop, where, in addition to replacing parts, they will also repair the entire chassis. But most experienced cyclists advise you to be able to make repairs yourself. This way you gain experience in maintaining and repairing your bike and in an unforeseen situation you can fix the breakdown. Replacing the rubber on a bike yourself is easy, it will take much less time than in a workshop, and save money.

  • The main reason is a punctured camera. To glue or replace it, you need to remove the tire. It is advisable to inspect it for stuck glass or other small sharp objects.
  • When the tread is heavily worn, the tube is more at risk of puncture. Even very small pieces of glass can damage it.
  • Bumps and other irregularities may appear. The camera begins to bulge out from under the tire. Therefore, you need to replace it with a new one.

Removing the tire on the road is harder than at home or in the garage. Especially if you don’t have the necessary tools. This is possible, but very difficult. Especially when the rubber stuck to the rim like a glove. Therefore, it is best to take a puller and other tools for repairing a bicycle with you on the road.

Replacement tools. Removing the tire

  • We release the brake. Different bike models have different brakes. If they are disc, then you just need to unscrew the eccentric or nuts. Bicycles with V-brakes are the most common. You need to unfasten the brake levers, pull out the brake cable and spread the levers to the sides.
  • We remove the wheel. It is advisable to turn the bike upside down. Turn over carefully so as not to damage the elements mounted on the steering wheel, such as a bell, lamp, mirror or brake levers. The front wheel can be removed without problems. To remove the rear one, the chain must be released. It is better to remove it from the smallest star.

Remove the wheel carefully

  • Letting off the air. To do this, unscrew the cap, press on the nipple and wait until all the air comes out. It is advisable to unscrew the spool completely. There should be as little air as possible so as not to damage the camera when removing.
  • We use pullers. To do this, insert a mounting or other removal tool under the tire and pull the tire out of the rim edge. After 10-15 cm, we pry the edge with another spatula. We move the second puller in the opposite direction from the first along the circumference, until one side is beyond the edge of the disc. If you only need to remove the camera, then these actions will be enough.
  • Remove the tire. After removing one side, use a puller to remove the other side, applying the same steps.
  • There are many manufacturers that offer a wide variety of tire models. Tread patterns can be symmetrical or asymmetrical. In the first version, you can put them on the bike either side. In the second, the protectors are usually directed in one direction or another.

    Some manufacturers mark their tires with arrows and Front and Rear labels. The direction is immediately visible in them. There are also front-only or rear-only models. This is indicated by the corresponding inscriptions and arrows. Failure to follow the manufacturer’s recommendations will result in poor traction, poor bike handling and rapid tire wear.

    Some V-type models are missing markings and arrows. Then experts recommend to put tires on the front wheel with a tip to the rear (\ /), and on the rear wheel. with a tip to the front (/ \). This is due to the fact that the rear wheels perform the function of traction, and therefore must rest on the road with their “legs”. And the front ones perform more the braking process, and the “legs” in the figure should look forward.

    These guidelines are for cycling on unpaved roads. If you drive on the highway, the directional options of the arrows have a minor function. With an increase in cross-country ability and traction, you can put both rubber with the edge forward.

    How to install a tire?

    • We place the camera on the tire. Make sure it is not twisted. To do this, we slightly pump it up with a pump.
    • We put on the tire. This must be done carefully with a puller. First we put one side inside the rim. Then we press the valve in the spool, release the air and put the tire on the other side with a spatula. It is necessary to check if the camera has become correctly and slowly inflate it, paying attention to whether the tire has become even.
    • We put the wheel in place. Put on the chain, fix the brakes.

    There is nothing difficult in replacing. Even beginners can handle this. The main thing is to remember that everything must be done carefully. Tires constantly require replacement, and punctures, in general, are difficult to protect. Therefore, a little effort and time, the availability of the necessary tools. and replacing the tire will not be difficult.

    How to change a tire on a bicycle. Velobaggio

    Not everyone punches their own wheels, and not everyone repairs a bicycle on their own. Nevertheless, understanding how you can remove a tire from a bike and put in what is needed for this and how to do it easily and without unnecessary problems is useful for most riders.

    When we take off a bicycle tire?

    • The camera is broken. you need to remove the tire, then change the camera, and then assemble the wheel;
    • When replacing, in fact, bicycle tires. they tend to wear out, especially with aggressive or prolonged driving;
    • When servicing the wheel. when other elements, for example, and the camera, can interfere.

    Different tools will be needed depending on the bike design.

    The minimum set is hands (preferably with gloves), nothing else is needed. What is used to facilitate the process?

    • Dismantling a bicycle wheel. small oblong plastic plates with a “hook” at the end. Very helpful to hold the edge when starting to dismantle without effort, and then remove it.
    • Any replacement of the folding. keys (from locks or wrenches), coins, sticks are often used (which is quite traumatic, by the way).
    • Keys for removing the wheel. there are also models where the axle is fixed with bolts, and not eccentrics.
    • Pump. needed when installing the wheel back.

    Sequencing

    So, what needs to be done to remove the tire from the bike?

    • We begin to remove the wheel by washing out the brakes (in the case of V-Brake) or removing the caliper (disc), they can greatly interfere with the next steps.
    • Loosen the bolt or eccentric that holds the wheel in the frame.
    • We take out the wheel.
    • We release excess air from the chamber through the nipple, it is important that there is as little air as possible, otherwise the camera can easily be touched and damaged.
    • We pry off the edge using a flanging or replacing it at one point.
    • We measure 10-15 cm and repeat the operation, bending back the segment between the two bevels, and, taking it outside the rim, out.
    • Carefully continue removing the tires until one side is completely behind the rim.
    • We repeat the action in the same direction with the second side of the tire. Usually this stage is already easier.
    • Done!

    Repair of the camera only is limited to items 1-7.

    The reverse process is similar:

    • It is necessary to put on the tire, starting to lay it inside the rim with one side.
    • On the last 15-30 cm, we fix one side of the tire with a bead and carefully transfer the entire edge inside the rim.
    • Place the edge of the tire inside the rim and install the camera.
    • We repeat the process of bending through the rim with the second edge of the tire to finally put it on.
    • Done!
    • We mount the wheel, close the brakes.

    Do not forget that all actions should be carried out correctly. Rubber does not like heavy loads, especially the thin and soft rubber used in chambers. All operations with the tube inside the tire should be done delicately.

    Do-it-yourself tire removal is easy, and most riders do this repair exercise the first time around. Accuracy of execution, availability of convenient tools. and changing the camera will not be difficult.

    How to remove and change a wheel on a bicycle. Removing and installing bicycle wheels

    This article will guide you through removing and installing front and rear bicycle wheels.

    Removing wheels

    If possible, start by setting up your bike. It must be installed on the left side when removing the rear wheel. Do not stand the bike in an upright position without the rear wheel, as this may damage the rear derailleur.

    Rear Wheels: Set the derailleur to the outer gear and the inner front wheel chain. This will loosen the chain and the wheel will be easier to remove.

    Disconnect the brake rim, if equipped. The release mechanisms of typical MTB and road brakes are shown below.

    Note: Disconnect pads are not required with disc brakes. Also, with hydraulic disc brakes, do not squeeze the brake lever when removing the disc from the bike. Otherwise, the pads will close and it will be very difficult for you to put the wheel back on the bike. Use a specially designed spacer such as PP-1.2 if needed.

    Detach the wheel from the frame:

    • Eccentric mechanism for securing the axles of the wheels: pull the lever of this mechanism outward to the end. If necessary, loosen the quick release of the adjusting nut to remove any projections on the end of the fork.
    • Straight axle: some functions are the same as the eccentric axle for securing the wheel axles. pull the lever outward to disengage and turn to loosen. Some straight axles are equipped with a special device that should weaken the axle. However, other simple levers that are needed to loosen or tighten are not used.
    • Solid axle: on wheel axles with nuts, both nuts must be loosened from the outside.

    On the front wheel. simply point the wheel down and out of the fork. For rear wheels, pull on the rear derailleur so the screws clear the chain. Lower the wheel down through the brake pads and forward to clean the chain and shift mechanism. Some shift mechanisms have a clutch mechanism that makes them difficult to turn. They have functions that make it easy to remove the wheel.

    • To engage the SRAM shift mechanism, move the lower roller forward to loosen the chain and press the button to lock it in place.
  • To engage the Shimano shift mechanism, you need to find the on / off lever and move it to the inoperative position.
  • Wheel installation

    The wheels must be installed properly on the bike frame. Misalignment can lead to problems with shifting and adjusting the bike. If the wheel is not securely fixed, then it can fall off during the ride and injure the cyclist.

    Rigid axle bushings use axle nuts on the outside of the frame plate. The axle nut contains a washer built into it, or a separate washer. If the washer has teeth or knurls, then they are connected to the recess to secure the wheel. Lubricate the threads on the axle when the wheel is mounted on the bike.

    It is often easier to mount the front wheel when the bike is on the ground. When placing the bike on the ground, the axle must be completely in the pad on the frame.

    Check that the cam lever for locking the axles of the wheels is in the open position and that its brakes are open.

    Place the wheel in the frame pad. Make sure the hub is fully seated in the frame or fork.

    • On the rear wheel, first rotate the shift mechanism back and place the smallest gear between the top and bottom of the chain. Place the wheel between the brake pads by hooking the smallest gear on the chain.

    Tighten the wheel:

    • Cam mechanism for securing the axles of the wheels: tighten the axle until the lever meets resistance 90 ° from the frame or fork.
    • Straight axle: move the axle in place and turn clockwise until it stops.
    • Solid axle: tighten both nuts on the axle until they stop.
    • The use of a torque wrench is recommended. However, if it is not available, an effort must be made. For 25 Nm, apply about 40 pounds of pressure to the end of a 5 “wrench.

    Determine the end position of the lever closing. Rotate the front arm and adjusting nut so that the arm ends up just at the front of the fork. Place the rear arm between the chain support and seat. Reposition the lever as needed if it is not fully closed.

    Re-remove the brake mechanism if applicable.

    Make sure the wheel is in the center of the frame or fork. Loosen the nuts on the axle and, if necessary, adjust the center of the wheel in the frame and retighten.

    Make sure the brake pad rim is centered on the wheel and adjust as needed.

    Additional Information

    Quick release

    The eccentric mechanism uses a hollow hub axle to secure the wheel axles, equipped with a shaft, a lever that acts as a cam mechanism and an adjusting nut. The cam exerts tension on the shaft and pulls, and the adjusting nut is pressed firmly against the pad on the frame. This tension holds the wheel securely to the frame.

    The adjusting nut determines the amount of tension on the cam lever for the cam mechanism and wheel axles. Lubricate the cam mechanism if it is sticky or dry.

    The eccentric mechanism for securing the axles of the wheels is equipped with two conical springs. The small end of the spring faces the axis and the large end faces outward. These springs make it easier to fit the wheel. If one or both springs are twisted or damaged, they can be removed. They don’t matter as long as the wheel is firmly attached to the bike.

    The so-called “open cam” may require more tension. These levers are cam gear and must be lubricated frequently.

    Disc brakes

    Bikes that use disc brakes on the hub need special attention. Wheel disc brakes (Dual Pivot, Linear Pull, Cantilever, Sidepull, etc.) generally do not use significant axle pressure. Disc brake systems are fork mounted and apply a load to the rotor that is attached to the hub.

    There is an external hub axle load that tends to push the axle out of the frame pad. It is especially important to secure the pin properly in disc brake systems.

    Solid axis

    The rear frame pad in the solid axle can also have a bolt-on gearshift mechanism. There should be a bolt and a nut that holds it. The wheel is mounted on a suspension. The axle should be located on the back of this bracket, which moves the right side forward. Tune the wheel and check the nuts.

    Understanding the question of how to replace the bicycle wheel camera

    There are more and more people who like to ride with the wind on a two-wheeled iron friend. The number of those who are faced with the everyday problem of punctured wheels is also increasing. Changing them is not the most difficult thing, but skills are needed here and there are some rules. This article will help you figure out.

    Preparatory step before removing tires

    Immediately, as soon as you notice that the wheel is “flat”, get off the bike. Further long-term movement on an iron horse in this form will damage its moving parts even more. It is better to repair a wheel in a special room. It doesn’t rain on you there, if it has gone, and there is all the necessary tool.

    What a cyclist should always have in stock:

    Ideally, there should always be a repair kit, a spare chamber, a pump. Together, this makes up an impressive weight and takes up a lot of space. For a small bike, this is inconvenient, but it is not always possible to limit yourself to ordinary gluing. What you definitely can’t do without:

    READ  The handlebars of the bicycle rotate separately from the wheel

    All of the above will help to dismantle the damaged wheel and install a new one, with the installation of the camera.

    Repair kit

    • Degreaser. Required when gluing damaged elements. Before applying the patch, they wipe the glued surfaces.
    • Stripping tool. Metal tool to pre-strip the camera.
    • Glue. Special glue for gluing rubber elements.
    • Patches. Made of rubber. There are several of them in the kit and they are different.

    Dismantling a bicycle wheel

    Cyclists, especially inexperienced cyclists, have problems with bending the tire bead using only their hands (dismantling process) In this case, use a special tool made of plastic or metal, of a small size, it is called a pry bar or a ripper blade. He helps to cope with this task and to put the tire in place.

    Tire replacement procedure

    We have prepared everything necessary for the repair, let’s proceed:

    • We dismantle (remove) the damaged wheel. To do this, loosen the screw and raise the chain.
    • Remove the protective cap from the nipple, release the air from the chamber. If the spool is like in a car, press the button in the middle with a sharp object and hold it until the air leaves.
    • We hook the edge of the tire with a special tool or other suitable object in two places at a short distance from each other. We take it out of the rim. The use of special tools is preferable for repairs, it is professional and convenient. However, in the absence of it, use what is at hand and suitable for these purposes. Wrenches (not thick), a spoon will do. Items should not have sharp edges to avoid damaging the camera. Do not apply excessive physical force to the camera, otherwise damage it further. Try to do everything with the necessary effort, but carefully. If using metal objects, be careful not to let them fly off and injure you.
    • We take out the camera without using an additional tool, just with our hands. We take out the spool (nipple) and then the camera itself.
    • Check for serviceability of the rim, integrity and working condition of the tire.

    The first stage of repair work is completed, we are starting to install the wheel

    • Make sure the rim, tire and tube are free of sharp, foreign particles and protruding parts (e.g. spokes).
    • Pump up a little camera.
    • Check the spool, insert it into the rim hole.
    • Place the camera carefully in the tire cavity.
    • Using a special tool, or other suitable tool that does not have sharp edges, tuck the edges of the tire into the rim. If you can do it only with your hands, then the tool is optional.
    • Pump up the wheel, knead the tire. The camera should unfold freely, creases are not allowed.
    • Place the wheel on the bike and secure with the screw.
    • Inflate the chamber fully and screw the caps on the nipple.

    The wheel repair process is over and you can go further.

    Any cyclist can change a tire. Be prepared for necessary repairs, carry tools and materials. Having fixed the bike with your own hands once, you can also help your friends with advice and deeds.

    How to remove and change a wheel on a bicycle

    Bicycle wheels are mounted on the frame: the front wheel is on the fork dropouts, the rear wheel is on the feather dropouts. Repair, cleaning and lubrication may require removal. There is no need to roll the bike to the service for this occasion, since everyone can remove the wheel from the bike right at home.

    Why do you need to dismantle the wheels? As a rule, these are bulkheads of bushings, repair of spokes and rims, cleaning a bicycle and the notorious replacement of tires.

    Removing the front wheel with rim brakes

    Place the bike upside down on the saddle and handlebars before removing the wheel. Beforehand, all accessories. mirrors, front lights, bell, decorative elements. should be removed so that they do not interfere with work and so as not to damage them. It is advisable to put a soft cloth under the sensitive shifters to avoid damaging them under the weight of the bike.

    Briefly, the front wheel is removed according to the scheme:

    • Release the rim brakes.
    • Loosen attachment to dropouts.
    • Carefully remove the axle from the legs.

    It is necessary to release the brakes in order to easily pull out the wheel and not damage the system. To do this, squeeze the connecting arch and unscrew its fastening with a hex wrench. The brakes are now free. An alternative option is to remove the pads from the brake mechanism, however, after assembling the wheel, they will have to be adjusted again.

    Wheel fastening on a bicycle is presented in two versions. nuts for 15 and an eccentric. To remove the axle from the dropouts on the nuts, you will need two keys. one will act as a worker, and the other as a lock. Unscrew one nut counterclockwise while holding the opposite.

    What can you use? Traditional open-end or spanner wrenches. The second option is even more convenient and easier to grab the nut. Adjustable wrenches with wide lips are not recommended for work, as they can “eat” the corners of the nuts.

    With an eccentric, it is much easier. loosen the bolt and raise the locking lever. If the spring is not weak enough and the lever does not rise fully, loosen the bolt harder. Actually, removing a wheel at home is as easy as shelling pears.

    In this section, the topic of removal with V-brakes was touched upon. With discs it is even easier, and even more so with singlespeeds with a kick drum on the rear hub. There is one limitation for a disc brake system with hydraulics. do not keep the bike upside down for too long, as the pipes are airy. That is, the wheel was removed and the bike was returned to its normal state during repairs or other manipulations.

    Removing and installing tires

    A tire breakdown on the move is an unpleasant phenomenon that can be found anywhere. Can even lower at home. You can’t ride, you have to change the camera, tire or all together. For a solution to the problem, you can contact the service, but in addition to money for a new consumable, they will also take on work. And why spend extra money and strain the wizard, when all the manipulations for removing and installing tires can be done independently? Let’s look at how to disassemble a bicycle wheel and assemble a tire. You will also have to remove the tires and put them back on when straightening the rim or replacing the spokes.

    change, wheel, bicycle

    For work, you need special plastic assemblies or two small shoe spoons. It is undesirable to use screwdrivers, as they can damage the rim.

    How to disassemble a wheel:

    • Fully deflate the tire (if removed to repair the rim, not replace).
    • From the side opposite to the nipple, pry off the bead of the tire with assemblies and fasten them to the spokes. The distance between the blades is not less than 20 cm. With the third assembly hook up the bead in the middle and pull it out of the rim.
    • Remove the assemblies and pull the tire off the wheel. If there are only two blades, we fix one, the other is carried along the board, pulling it out.
    • Pull the nipple out of the bore. On some models, it can be attached with an additional nut, then we twist it.

    Now, when there is a new kit or the wheel is repaired, you need to put the tire back on, or fence:

    • Pump up the chamber to 0.5 atm so that it takes a rounded shape and does not break.
    • Insert the nipple into the hole, the chamber on the surface of the rim. It is important that it matches the wheel size exactly.
    • Compress the tire beads and insert from the nipple side.
    • Sequentially distribute the edges around the entire circumference with your hands.
    • It will take force on the opposite side to press the bead.
    • Inflate the tire to the correct pressure and put the wheel on the bike.

    It’s so easy to bend the wheel with your own hands.

    How to properly install the wheel and tighten the mount

    The installation process in its rightful place is strictly opposite to dismantling:

    • With regard to the direction of rotation “forward” insert the axle into the dropouts.
    • Adjust position (for rear).
    • Tighten nuts or eccentric.

    Wheels are put on a bicycle only with tires, otherwise it will not work to put the tires on the rims. “Forward” on an inverted bike. backward, look at the top. Arrow, feet and other pointers should point in this direction.

    On rear dropouts, the axle position relative to the chainring may fluctuate, and its distance affects chain tension. The optimal position is the one recommended by the manufacturer, “all the way”. It should be noted that the dropout adjustment of the rear wheel is valid for models with one gear and planetary bicycles.

    Tighten the nuts. Sometimes the mounts are equipped with additional washers-stoppers against axle rotation. If the manufacturer foresees it, we set them. Next, the nuts on both sides are thrown by hand. Again we take two keys: on one side the nut is fixed, on the other side it is twisted. Then we go to the other side and tighten the mount until it stops. The technical data sheet for the bike indicates the tightening torques for the fasteners. Following these guidelines will ensure uniform force distribution and optimum geometric integrity.

    • Set axle to dropouts.
    • Turn the bolt clockwise.
    • Press the lever and fix the eccentric.

    The locking lever should move with some effort and be free to lower to the end. If it folds too easily, you need to tighten the bolt, does not fall. loosen.

    The wheel removal procedure is the first step to fixing rim defects and replacing tires on a bicycle. Changing tires or temporarily removing them with your own hands is just as easy, just take a little space and time.

    How to Quickly Remove a Rear Wheel on a Speed ​​Bike for Repair

    A high-speed bike means independence from public transport, city traffic jams, plus exercise and a healthy lifestyle. Like other means of transportation, it must be inspected and repaired on time. And that means you have to disassemble. One of the problems that beginners may face is how to remove the rear wheel on a bike at speeds and then put the element back in place. If this is done incorrectly, the deformation of the mechanism is not excluded.

    When is it necessary

    Like any vehicle, a bicycle must be inspected and repaired in a timely manner. One of the mandatory procedures is to separate one or all wheels from the frame. The reasons when dismantling is required may be:

    Take the survey

    • significant damage or malfunction of the rim;
    • damage to spokes, tires or tubes;
    • bike sleeve repair;
    • replacement of a wheel as a result of the complete dilapidation of the old one;
    • chainring wear.

    In addition to preventive maintenance and repair, dismantling may be required if the bike is in good working order. For example, when you need to move to another place, but there are no mounts for the car roof. Then it is more convenient to disassemble the vehicle into parts in order to transport it in the trunk or cabin. In such a situation, you should definitely know how to properly remove the rear wheel on a bike at speeds.

    Dismantling and assembly are simple procedures, but only if you know the sequence of operations. In addition, an independent department has a number of other advantages: there is no need to spend money on workshop services, you can do everything anywhere at a convenient time. Plus. improve your service skills at the same time.

    If for experienced cyclists this is a matter of a couple of minutes, beginners or less experienced riders will have to spend more energy to master the wisdom of how to remove the rear or front wheel from a speed bike, and then put the elements back.

    Step-by-step instruction

    Before removing the wheels from the bike, you need to understand the features of the brake system installed on it. High-speed bikes are produced with different types of devices that differ in the principle of operation. The easiest dismantling. if there is a disc brake, complex and more time-consuming. if there is a rim system. If you do not pay attention to this, but immediately get down to work, there is a high probability that the system will be blocked so that the wheel will be fixed forever, and it will become impossible to remove it.

    Disc brake Rim brake system

    Removing a wheel

    It will be easier to work if you do it in a place where it is convenient to approach the bike from either side. Dismantling wheels from a bicycle with rim brakes is carried out according to the following scheme:

    • Release the brakes. unclench and bring the levers towards one another, then. lift the swing lock.
    • Loosen the chain. turn the wheels as much as possible, installing on the smallest sprockets at the back and front.
    • If the tires have a large diameter or large tread. release air.
    • Turn the “car” over, placing it on a special stand or just on the floor. The main thing is that the emphasis on the steering wheel and seat is stable, and the bike does not fall over. However, if it is equipped with a hydraulic brake system, this position is highly undesirable, as there is a high probability that air will enter the brake line. Keep the bike upside down as little as possible.

    Release the brakes Loosen the chain Unscrew the wheel

    Loosen the chain before removing the rear wheel of the bicycle. To do this, you need to set the minimum gear ratio (asterisk). Further, the course of work depends on the type of attachment:

    • Nut. Install two keys on opposite sides of the wheel, holding one stationary. Twist the second in the opposite direction clockwise. The nuts can be removed completely or only loosened to remove the wheel.
    • Eccentric. Loosen the fastening by lifting the lever up, on the back side. slightly unscrew it, making a couple of turns against the clock hand. Taking a rag in your hands so as not to get dirty, take the wheel slightly to the side to remove it from the mount. The chain is removed last.

    Before removing the front wheel, the eccentric clamp (located to the left of the hub) must be turned 180 °. On the right side of the sleeve, turn the nut a couple of turns. It remains to free the front wheel from the bike by removing it from the fork tip.

    If the bike has disc brakes, then before removing the wheels, you need to take care that the discs do not accidentally close. Otherwise, you will have to spend a lot of time and effort on unclenching. To prevent this from happening, you need to insert into the slot any object (a piece of cardboard, folded paper) or a plastic plug (included in the kit).

    Nut fastening Eccentric

    Wheel installation

    There is no difficulty in work when you have knowledge of how to mount the rear or front wheel on a bicycle. All dismantling operations must be performed strictly in the reverse order:

    • Slide your bike chain over the smallest sprocket. Insert the wheel into the housing mount, being careful to hit as accurately as possible. Check if the part is fixed correctly.
    • Tighten the nuts with a wrench, for a bike with an eccentric. turn the lever in the opposite direction.
    • If the bike has a rim braking system, secure it by clearly mirroring the sequence of dismantling operations to ensure safety when driving.

    If it is required to install the front wheel on a bicycle with a disc brake system, then at the same time during installation, insert the brake disc into the gap between the pads. If they are crowded and the space between them is too small, you can expand it with a screwdriver.

    All manipulations must be done without undue effort, otherwise burrs will form on the pads.

    Finally, it is imperative to test all the mechanisms of the bike. If deficiencies are identified, remove the wheels and repeat all over again. You should not neglect the check, because the condition of the bike directly affects safety. After making sure that everything is done correctly, screw the previously removed accessories to the bike.
