Remove the rear wheel of the bike with speeds

How to disassemble or reassemble the rear wheel of a speed bike

Removing the wheels from the frame is part of a mandatory bicycle 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-repairing wheels, and it is no coincidence: it’s cheaper, and you will gain 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.

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 is more often the case with punctures, then simply unscrew the cap.

To remove the tire, you 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 sides 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 it very carefully so as not to damage the rim, you should 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.

Attention! The camera must lie flat, without kinks, otherwise you will have to reinstall it. There must be a flipper at the bottom of the rim to protect it from the spokes. If it is torn, you need to install a new one or get by with two layers of thin electrical tape.

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 bike, the forward direction is backward in the lower position. However, the rear wheel of a speed mountain bike is easy to go wrong, thanks to the cassette on the side. After mounting, the camera is inflated.

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:

  • noticeable damage to the rim;
  • complete wear when a wheel needs to be replaced;
  • a flat tire or a burst tire;
  • bulkhead bushing.

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

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, a bell and a lantern in advance so as not to damage them under the weight of the frame. V-brakes are first released and disassembled, 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 wrenches.

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. It is recommended to use open-end wrenches or box wrenches. The adjustable version is undesirable, as its thick horns “eat up” the corners of the nut due to loose fit and sliding.

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’s 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, the 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 bearings of the hub, you will need to temporarily get rid of the rear sprockets.

The rear speed device is removed using a puller and a so-called whip. Removing the cassette is a short-lived affair, but it will take 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, you should slightly loosen the spoke tension. This can be done using a round key with knock-out holes for different diameters of the knitting needles. You need to loosen 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 wear under dynamic loads.

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 disassembling, replacing, lubricating or adjusting. 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 the following order:

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

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 spin 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 to a bicycle, it turns out to be not so much. What’s more, with experience, a wheel bulkhead will take minutes.

Dealing with the problem

Removing the wheel from the bike may be necessary in various cases. For example, you have a puncture or your tires need to be replaced due to high levels of wear. But you never know what can happen. Someone will say that some kind of puncture does not require large-scale work. There may not be large-scale ones, but they are performed with knowledge of the matter. The quality of your work will determine how well you can continue to ride. And there is something to think about. Modern high-speed bicycles are produced by various companies and often with their own characteristics. It is on them that you need to pay attention.

For example, first you need to understand what kind of brake system is on the rear wheel of your bike. It is with him that all your work will begin. If you are a disc brake owner, then you shouldn’t have any problems. If the rim, then your actions will require a little more effort. If you forget about this kind of brake and do not release it, then you will never be able to remove the wheel, no matter how hard you try. So, we have decided on the brake, now we go directly to the process of removing the wheel.

How to remove the rear wheel of a high-speed bicycle with disc brakes with your own hands?

How to remove the rear wheel and sprockets from a speed bike with disc brakes?

The bicycle is the most popular and convenient means of transportation. It is convenient and comfortable to travel on it both in the city and off-road. High-speed bicycles provide a lot of opportunities to feel comfortable even on a rather problematic road. But in order for your pet to continue to delight you further, he needs appropriate care, and the owner’s ability to cope with unforeseen circumstances will also come in handy.

Action plan

To get started, make your work environment comfortable: flip the bike over on the handlebars and position it so that you have free access to the wheels from different sides. And here we also remember about the brakes. If your brake is hydraulic, then these models absolutely do not like being held upside down. And in case of replacing the rear wheel, the brake should be pumped so that no air would get into it. Do not ignore this moment, despite its laboriousness, if you want your brakes to remain as reliable.

There are various types of wheel attachment to the axle. If it is on nuts, then your actions are not difficult and understandable. If the option is an eccentric, then you should not be intimidated by complex names. The process is pretty straightforward. Move the chain to a smaller sprocket. On the left side of the hub is a lever that controls the eccentric clamp. Unscrew this lever by rotating it counterclockwise 180 degrees, but do not rotate around the hub axis. There is a special nut on the right side of the sleeve, which should be unscrewed a few turns.

Eliminate the puncture

The wheel has been removed, but the puncture site is not yet available. To do this, it is necessary to deflate the wheel and disassemble it. If you do everything right in a short time, the damaged camera will be in your hands. The puncture site should be cleaned and sealed with a special pad, which will reliably cover the damaged area and prevent air from leaving the wheel. If the damage is serious, then the camera needs to be replaced.

Removing a bicycle wheel will not be difficult for you, and with practice, the necessary skills will come. It is also important to put it back in place correctly. The technology itself is simple and requires basic knowledge. If you do not want to go to the service, but decided to do everything with your own hands, then with a certain level of desire and diligence, you will succeed.!

how to remove the rear wheel of a speed bike

HOW TO PUT THE WHEEL IN PLACE

To do this, you need to make sure that the chain fits on the sprocket as expected. Therefore, first put on a chain on the sprocket, and only after that we put the wheel on the mount. If you have gloves, put them on, otherwise it is very difficult to wash your hands after such an installation. Slide the wheel into the mount so as not to confuse the rotation.

It is required to fasten the wheel firmly enough so that it does not fly off when driving.

Put the brakes back in place, as it was the wound, this means the rim brakes.

It happens that it seems as if the chain is twisted or is not correctly placed on the sprockets, it gets tangled. Just spin the chain back and forth using the pedals, or by hand, without removing the wheel, the defect should be corrected. If you move the gearshift mechanism located in the chain mechanism aside and put on the released chain as you wish.

After all procedures are completed, perform a test drive. Check how the brakes behave, whether the patch is missing, and then you can safely go further on your business.

We glue the camera

It is necessary to determine exactly where the puncture happened. This is done before removing the tire from the rim. Try to find the item that punctured. He often looks out from the punctured site. Pull it out, and mark the damaged area.

Carefully remove the tire, having previously marked the puncture site on the camera. This will localize the damage site in an area of ​​several centimeters. Of course, if it is possible to put the camera in water, you will find the punctured place much faster, but small cracks cannot be discerned with the help of water, moreover, you should subsequently dry it.

You can wet your fingers to find the puncture site and run them around the camera. Wet fingers are more likely to find this place thanks to the released air. Another way is to place the camera to your ear and listen. You need to hear a hiss coming out of the damage site.

If you have visually identified the puncture site, then you can perform repairs without removing the wheel and without performing disassembly. This will save you time and reduce labor costs. But, the quality of the repair may suffer from this.

Please note that there may be several damage, so make a thorough inspection of the camera over the entire area. Mark all punctures. Sometimes there is a double puncture with the same object, so look at both the top and the inside of the camera.

Feel the inside of the camera too, it happens that this is the only way to find the object that made the puncture. Be careful, as the object that could pierce the camera is likely to be quite sharp, do not injure your hand.

When gluing the camera, read the instructions for use of the first aid kit or rubber glue in advance. Usually, you clean the punctured area with sandpaper, degrease the gluing site, apply on both surfaces that you will glue the glue, wait about 5-10 minutes for the glue to finally set, and press the surfaces against each other with force.

In this case, the main thing is strength, and not how long you will stand holding the rubber. That’s it, the camera is ready for further use. But there is one caveat, if the puncture is made in cold weather, then the glue can dry for a very long time, if it dries at all.

After the work on sealing the chamber is completed, it is necessary to perform a trial pumping. Before finally installing the camera, pump it to check the effectiveness of the repair. In order to find out if the camera is leaking, press on it and, if there is no hiss at the place of repair, then everything is in order.

If there is water, check with it. If the air does not come out, then you can install the camera in place.

If things are really bad, there is nothing to repair, but you need to go, then use the means at hand, everything will do: scotch tape, adhesive plaster, electrical tape, your actions should be aimed at reducing the release of air from the chamber. Thus, you can get quite far, the main thing is not to get discouraged.

Disc brakes

Bicycles using 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 which tends to push the axle out of the frame pad. It is especially important to secure the pin properly in disc brake systems.

Installing the rear wheel

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 the nuts or eccentrics, they should be tightened well so that the wheel firmly sits on the frame.
  • Fasten rim brakes if fitted. Return to the previous position in exactly the opposite 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.

Replacing the bearing of the rear wheel of a bicycle will not cause you any difficulties if you understand all the nuances and features of servicing this part. The condition of the bearings, their timely maintenance and replacement is the key to safe driving.

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 creates 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 have a cam mechanism and must be lubricated frequently.

Disassembly, cleaning / lubrication

How do I remove the rear wheel hub on my bike for cleaning and lubrication? The following procedure is required:

  • the cassette is dismantled with a puller;
  • the stopper opens;
  • washers with bearings are removed;
  • troubleshooting is carried out by examining the surface of the bearings: worn out elements must be replaced, the rest are cleaned with a solvent;
  • the axis is removed;
  • inside the case is cleaned with a soft cloth, all elements are lubricated (special attention must be paid to the bearings).

How to assemble a bicycle rear wheel hub? Assembling the rear wheel of a mountain bike or any other bike is carried out in the reverse order. When installing parts inside the case, you must first put grease on its walls.

The rear wheel is then replaced. How to do this is shown in the video.

Before proceeding to disassemble the rear wheel of a bicycle to repair the hub, you must clearly understand the order of these actions. Otherwise, the situation will only get worse. If you are not 100% confident in your own abilities, watch the video, which will tell you everything in detail.

GASKETING THE CAMERA

  • First of all, you need to determine where the camera is pierced. To do this, the camera needs to be pumped up and examined carefully. A characteristic hiss will be heard at the puncture site. This place needs to be marked somehow.
  • Then you need to free the chamber from air by pressing the nipple tongue.
  • Your repair kit should have fine sandpaper, you need to take it and rub well the place where the tire pierced.
  • Now you need to apply a thin layer of adhesive. This is done in such a way that the piece on which the glue is applied is slightly larger than the patch in size.
  • Let the glue lie down for a couple of minutes, and then you should glue the patch from which the protective film has been removed in advance. Be careful not to get air bubbles under the patch.
  • Now press the patch against the camera for as long as possible.

After gluing the inner tube, run your hand over the inside of the tire. It is not uncommon for the cause of the puncture to get stuck in the tire, and if so, then it must be removed. Don’t forget this moment.

WE CARRY OUT REPAIR OF THE REAR WHEEL BUSHING, CARRIAGE AND PUNCHED WHEEL

To repair a bicycle with your own hands, you must have certain skills and knowledge. In this article, we will tell you how to repair the rear wheel hub of a bicycle, repair a bicycle carriage, and also tell you how to fix a puncture in the rear wheel of a bicycle on your own, and for novice cyclists, we will tell you what pressure in a bicycle tire should comply with the norm.

REAR WHEEL REPAIR: REMOVE THE PUNCH

To begin with, it should be said that the repair of the rear wheel of a bicycle can be associated with the elimination of the “eight” on the wheel or the filling of the wheel hub. However, since these are specific operations that require certain experience and tools, they deserve separate consideration, and will not be described in this text. Below we will tell you how to cope with a puncture of the rear wheel, since everyone can face this.

Before you start repairing a wheel, you need to dismantle it. The front wheel can be removed easily, but removing the rear wheel, for a beginner bike enthusiast, may not be such an easy task. Let’s take a closer look at how to dismantle the rear wheel.

WE DO REPAIR OF THE CAR

One of the most difficult parts of a bicycle is the bottom bracket. What to do if on the way she let you down, and there is no one to ask for help? Everything is simple, and after reading the text written below, using the minimum number of tools, you can easily disassemble and repair the bicycle carriage.

To disassemble the carriage assembly, the first step is to dismantle the stars and the connecting rod system. We will not dwell on this in detail, since it is not so difficult, and there is plenty of information on this topic on the net.

On pleasure bicycles and inexpensive “mountaineers” the carriage of the standard modification is installed. The order of its disassembly is indicated below:

  • First of all, you need to unscrew the lock nut on the left using a special key;
  • After that, we remove the carriage cup on the same side, using a 16 key for this (note that the right-hand thread is cut on the left side, and the left-hand thread is similarly made on the right);
  • If necessary, you will also need to unscrew the cup on the right. To do this, you need to use a key for 32;
  • Now we take out the carriage assembly. It is best to immediately flush and, accordingly, clean the carriage tube, first of all, the thread;
  • Next, we are engaged in flushing the parts of the carriage assembly with gasoline or kerosene, along the way we look at whether the bearings, cups and axles are intact. If necessary, you need to replace worn parts;
  • The next step is the same operations, only in reverse order: we screw the cup to the right to the very end;
  • Now you need to thoroughly grease everything with grease (lithol), put bearings on the axle, and insert it into place;
  • Next, you need to screw in the cup on the left, until the axis stops rotating. And now the cup needs to be gradually released, until nothing interferes with the rotation of the axis, and it will be smooth. It is worth remembering that backlash is not allowed;
  • The lock nut should now be tightened;
  • We make a final check of the rotation and the absence of backlash. If there is a need for this, then you need to repeat paragraphs 8-9.

REMOVING THE COVER

To gain access to the punctured tube, you will need to disassemble and remove the tire from the wheel rim. It takes some skill to do the sorting, so don’t be discouraged if you can’t do it right away. It happens as follows:

  • The wheel that you removed must be placed upside down with asterisks.
  • Now you need to remove the nipple cap.
  • The next step is to cling to the edge of the tire with the help of the bead blade and turn out into the middle of the wheel.
  • After fixing the bead vane, you need to take another one of the same, and perform the same actions along the circumference, thereby disassembling the wheel completely.

Since the tire has already been disassembled, it is already easily removed, and the process of removing the camera will not complicate you at all.

HOW TO REMOVE THE REAR WHEEL?

  • If your bike has rim brakes, the first step is to unfasten them. This is done as follows: you need to heap the levers to which the pads are attached, and raise the part that secures the cable.
  • Now you should turn the bike over with the saddle down, so that it finds its support on the handlebars and saddle. If your bike is equipped with a headlight or bike computer, you should be careful not to damage them.
  • Next, we will loosen the eccentric of the wheel holding the wheel on the frame.
  • Take a position behind the bike. Now you need to slightly unbend the lever in the rear derailleur, pull out the rear wheel, which should rise up without much difficulty.
  • All that remains is to remove the chain from the wheel sprockets. Now the wheel is disconnected.

REAR WHEEL BUSHING REPAIR

The most common problem that a bike’s rear hub can upset you is a loose or tight taper. If weakening is observed in the cone, then the wheel will begin to play strongly. In the second case, when the cone is tightened, the bicycle will move much more “tight” than in normal mode, and the bearings may crackle. One way or another, you need to repair the rear wheel hub of the bike as soon as possible.

To eliminate the backlash or, on the contrary, tighten the cone, wrenches are needed, most often they use a 15 mm open-end cone wrench and a 17 mm open-end wrench. First, you need to start loosening the locknut, after which you need to proceed to loosening or tightening the flare nut to the required position.

Ideally, there should be no backlash. Finally, the lock nut must be screwed into place. If the cone is adjusted properly, the wheel will turn easily due to the force of gravity acting on the reflector or nipple.

It also happens that the rear axle of the hub can be broken or bent. The main cause of such a malfunction is usually poor quality parts. If this happens, you need to completely replace the hub axle with a new, better quality.

When replacing the axle, or when going through routine maintenance, or during the repair of the rear wheel hub of the bike, so that it is more convenient to dismantle the ratchet. If the essence of the repair is just a tightening or loosening of the cone, then this action is not necessary.

To avoid possible breakdowns, you need to periodically undergo maintenance. Its essence most often comes down to adjusting the cone and washing, cleaning the components and lubricating the bearings.

Less often. they change bearings, oil seals or washers. The cost of repairs can result in high costs if maintenance was rarely carried out and in general the bushing was not particularly monitored.

For example, it happens that the bearings “eat out” the grooves in the bushing housing, this can happen because the axle was bent or not lubricated enough. In this case, in order to repair the rear wheel of the bike, you will need to completely replace the hub body, or maybe the wheel itself.

Therefore, in order to avoid such a situation, before going on a long bike trip, you need to carry out maintenance of your bike, and if problems are found, then fix them in a timely manner.

WHAT TIRE PRESSURE SHOULD BE?

Cycling enthusiasts have always been worried about the question. how much should the tires be inflated? This is especially true for beginner cyclists who do not yet have special skills and cannot immediately tell how much pressure should be in the tires of a bicycle in order to ensure a comfortable and safe ride.

In fact, there is no difficulty here. Most bikes have tire pressure indications on their tires that are best suited to that particular model. Most often, the pressure range ranges from 2.38 to 4.08 atmospheres.

These tire pressures are optimal when riding off-road or in the mountains. The volume of air in the tires of the “mountain” is quite a lot, therefore, there is no need to pump over its tires.

Also, do not forget that, given the low pressure and large volume, the pumping of the “mountain” wheels should be carried out no more than once a week.

To determine the pressure to which you need to inflate the wheels of the bike, you just need to read the inscriptions on the tire. Tire manufacturers usually indicate the value of the upper and lower pressure limits.

But unlike a mountain bike, tires in a road bike need to be inflated to a slightly higher pressure, since the volume of the wheels is small. The pressure value in the tires of the “road bike” should be in the range from 6.46 to 9.18 atmospheres. And the pressure check must be done daily.

The traditional way of checking is to press the wheel with your fingers, and if it does not push through, then you can move on the road. Everyone did this when they were little. But it is better not to engage in amateur performances and just pump up the wheels, depending on the indicators that the pressure gauge gave.

Bicycle tire pressures can also change depending on how much weight the cyclist has and what the road is made of. If the route of your trip consists, for the most part, of off-road, mountains or an ordinary rocky road, then pumped wheels are clearly not what you need.

Lower tire pressure will allow you to worry less about bumps while riding, and maximize traction control, while over-inflated tires are easy to fall. But the situation changes on a good highway, where well-inflated wheels feel much better.

If the tire pressure is too low (1.9. 2.17 atmospheres), then this is the cause of many problems. To begin with, the tire can break through from the slightest collision with a stone or bump, and if during this the tube is squeezed by the rim, it will be punctured in several places and it will be almost impossible to repair it.

In addition, there is also the likelihood of damage to the rim, and this, not only does it take a long time to repair, but it is also expensive. And last but not least, during a sharp turn, a tire with low pressure can come off the wheel, in which case both the rim and the cyclist will be damaged.
