Remove Rear Wheel Bicycle With Disc Brakes

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

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

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 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.

Action plan

First, 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 the case of replacing the rear wheel, the brake should be pumped so that air does not 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 variant is 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 sleeve 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

Removing a wheel from a bike?

Any experienced cyclist knows how to remove a bicycle wheel on his own. This action often has to be done when a wheel needs to be repaired, replaced with a tire, rim or spokes, or simply replaced with another, more reliable or new wheel.

However, on newer bikes with different derailleurs and many parts, it is very difficult to change the wheel for a beginner who can do something wrong and panic.

Let’s figure out how to remove the front and rear wheel of a bicycle on our own, together.

How to remove the front wheel of a bicycle

Before removing the wheel, you need to see what kind of brakes you have. If disc, then you can immediately proceed to removing the wheel. If the brakes are rim, then you must first release them to make it easier to remove the wheel. Every rim brake manufacturer has almost the same removal. It is enough to pull out the arc that connects the two pads, so the brakes can be released. And for this you need the upper arch that holds the pads together, press them together and unscrew the screw that holds the wire arch.

After that, we move on to removing the front wheel. For this:

  • Turn the bike upside down. It is important to do this carefully, so that the bike rests on the handlebar and seat. Various accelerometers, bicycle lights, bell and other sensors and instruments can be easily damaged on the steering wheel. You can place a soft cushion or rags under the speed switches to prevent scratching. If you have disc brakes with brake fluid piping to the brakes, then you shouldn’t keep the bike upside down for long. This will lead to the fact that air enters the tubes and you will have to bleed the brakes. It is not difficult, but it takes time and the process will be laborious.
  • Remove the front wheel. If the wheel is screwed on with a nut, as on a regular bicycle, then you need to unscrew it until the wheel freely comes out of the mountings. If the wheel is fixed to the rim with an eccentric, then it is enough to untwist this lever without tools and significant efforts. This mount is often found on mountain and sport bikes.
  • After that we take out the wheel from the mounts.

It is important to remember, however, that if you press the rim brakes without a wheel, it will compress the brakes and make it impossible to put the wheel back. Then you have to adjust the brakes again. But if you originally detached the rim brake arch, then compression will not occur.

How to put the front wheel back

To put the wheel back, you need to do the same as when removing, but in reverse order:

  • We put the wheel in the mount so that the rotation is not confused. The direction of rotation is written on the tire, but keep in mind that the bike is upside down. This is done in order to avoid when driving “eights”, because the wheel tire is arranged according to a special technology.
  • We fasten the wheel with a nut or an eccentric firmly enough so that it does not fly back when driving.
  • Flip the bike.
  • Putting the brakes back as they were if you have rim brakes installed.

After that, you need to check the wheel: how it turns and whether it brakes correctly.

How to remove the rear wheel

Removing the rear wheel is as easy as removing the front. However, before removing the rear wheel from the mounts, you must first remove the chain from the axle, and also open the brakes so that they do not interfere.

How to put the rear wheel back

Replacing the rear wheel is done in the same way as installing the front wheel. However, when installing the wheel, it is important that the chain fits correctly onto the sprocket. Therefore, first we put the chain on the sprocket and then we put the wheel on the mount. It is better to do this with gloves, because the chain will stain your hands and you will have to wash them for a long time.

If it suddenly seems to you that the chain is twisted or tangled on the sprockets, then you do not need to remove the wheel again. It is enough to twist the chain back and forth with pedals or by hand to make it fit. You can also move the gearshift mechanism, which is located in the chain mechanism, and then put on the released chain as you like.

Removing a wheel from a bike?

If you have never done something, you may find it difficult to do it. If you have never removed the wheels from a bicycle before, then you may also be afraid that you will not cope, especially with the rear wheel (after all, there is a chain, a bunch of stars and this tricky derailleur!). But now we will tell you everything about this simple operation. There is nothing supernatural here. We have already briefly touched on this issue in the article on how to disassemble a bicycle, and now we will open this topic a little wider. You will have to remove the wheel not only if you need to disassemble the bike for transportation or storage, but also in order to replace the camera, tire or spokes (we will devote a separate article to what the wheels of the bicycle are made of), get rid of the “figure eight “.

How to remove wheels from a bicycle with rim brakes

If you have rim brakes, release them first. To do this, slide the brake levers towards each other and lift the cable lock up.

If you need to remove both wheels, release both brakes at once so that you don’t have to turn the bike over again. If you have tires with a large tread or they are large in diameter by themselves, then you will have to bleed some air from the tubes. Now turn the bike upside down (if you have any accessories installed on your handlebars that may be damaged in this position, it is better to remove them in advance). The bike will stand stable enough for any operation, but if you have hydraulic brakes, it is better not to leave it in this position for a long time. air can get into the brake line, which will entail a not very difficult, but tedious and time-consuming process of bleeding the brakes.

How to remove the rear wheel of a bike

If you will be removing the rear wheel, then to make it easier to do, loosen the chain as much as possible by switching it to the smallest sprockets. The wheel can be attached to the frame and to the front fork in two ways: with two nuts (less often) and with an eccentric. If your wheels are secured with nuts that screw onto the wheel axle, then you need two wrenches. You just throw one on one side and hold it in this position, and twist the other counterclockwise. It is not necessary to unscrew the nuts all the way; it is enough to loosen them to the extent that they do not interfere with removing the wheel. In the event that the wheels are fixed with an eccentric, then everything is even easier: you don’t even need tools. Pull the eccentric lever towards you, then, holding the axle on the opposite side, turn it counterclockwise a few turns until the wheel is free. Everything, the wheels can be removed. Yes, and the rear too: just lift it up and remove the chain from the stars.

How to remove wheels from a bicycle with disc brakes

If you have disc brakes, just in case, insert something into the pads, in the slot where the disc was: if they accidentally close, it is very difficult to release them. And if you don’t open it, don’t put the wheel on. The role of “something” can be, for example, a piece of paper folded several times. And sometimes new bicycles come with a special plastic plug.

Assembly is carried out upside-down. To make it easier with the rear wheel, bring it to the attachment point, put the chain over the sprocket and after that insert the axle into place. Make sure the axle fits into the groove completely and symmetrically. Are you convinced that there are no difficulties in installing wheels on the bike? But there is one caveat: for the protector to work as it should, it must be oriented in the right direction. For ease of orientation, an arrow is drawn on the tire. in this direction the wheel rotates when the bike moves. But the fact that the bike is upside down when installing the wheels can be misleading. Therefore, take your time. This does not apply to the owners of bikes with disc brakes. it is impossible to confuse here. Do not over-tighten the cam, put the brakes back in place. Everything.

A bicycle, transport is quite convenient, economical and reliable, does not require investment in fuel, does not need a garage, is healthy, does not pollute the environment. But sometimes even in such an ideal vehicle, failures occur.

This is the most common puncture when you need to change a wheel. “Well, what’s wrong with that?”, Say experienced cyclists, but do not forget that due to the fact that the bicycle market is flooded with products from different companies and countries. manufacturers, each bicycle brand has its own peculiarity, and therefore, in order to correctly and quickly change the wheel, you need to know the order of actions.

First, you need to know which brake is on your bike. If it is a disc brake, then removing it will be much easier. Well, if you own a rim brake, then you have to tinker a little. It will be necessary to first unclench it, and only then remove it. If you forget to do this, then the wheel simply will not come off, no matter how you pull it.

Place the bike upside down, securely fastened to the handlebars and saddle. Do not forget to pre-remove all unnecessary accessories and equipment, such as a navigator or travel computer.

The brake lever and brake lever need to be protected during your actions, so wrap them in some soft material. Thus, you will save them from breakage.

If your bike has V-BRAKE brakes, start the process by squeezing the pads, these actions will lead to the possibility of removing the arc. Squeeze where the cable attaches to the wheel. You don’t need much strength here, and you will quickly cope.

The hydraulic brake does not like being held upside down, so if this is the first time you are replacing the rear wheel, do not forget to bleed the brake later, most likely it will get air.

Of course, you can ignore this advice, because the pumping procedure itself is a long and laborious process, but then your brakes will no longer be reliable, and then you will have to blame only yourself.

As you know, the rear wheel is attached to the axle of the bike. The types of attachment are quite diverse, and the whole procedure will be determined from what you get. If your wheel is fastened with nuts, then you need to have a couple of adjustable wrenches. Clamp the nut with one key, and unscrew the second with another key.

It is not necessary to unscrew the nut completely, it is enough to make a couple of turns with a wrench. See the wheel comes off easily.

What if you have a disc eccentric? It’s easier than you think. Place the chain on the smallest sprocket at the back.

On the left side of the bushing you will see a lever that is responsible for the eccentric clamp.

Unscrew the brake lever and rotate counterclockwise 180 °, from right to left. Do not twist it around the hub axis.

There is a nut to the right of the sleeve, turn it off a couple of turns, and slowly move the switch lever to the position and back

Without releasing the chain tensioner lever, slowly remove the wheel from the fork tip. That’s it, the wheel is off.

Don’t forget the chain that runs through the entire speed shifting system. It must be carefully removed from the sprockets, without touching only near the frame.

If you grab the wheel and gently pull it up, then it should come out without effort. It is worth paying attention to the following recommendation: in no case press the disc brake handle, otherwise the pads will shrink.

Now let’s talk about how to unbuckle a wheel, because many representatives of the stronger sex do not want to walk, saving their time, and change to four-wheeled or two-wheeled friends. Camera puncture is quite common. Therefore, in order to quickly perform this operation, it is necessary that you have special tools that will help you cope with the trouble and get back into operation with your vehicle.

What is disassembly and how is it done. In words, it’s quite simple: you have to remove the tire from the rim or disc of the bicycle in order to carry out the process of replacing or gluing the camera later. To do this, you need beads, but if you have screwdrivers available, they will work too.

How to unbuckle a bicycle wheel

Bicycle wheel disassembly

We carry out the process of removing the wheel. How to do it mentioned above.

Now you need to lower the wheel, because without this, you will not be able to remove the camera. We find the cap that is screwed onto the tire nipple, turn it over in the opposite direction and insert it into the nipple and start twisting.

If you do everything correctly, you will hear the sound characteristic of the descent wheel, the hiss of air bleeding through the opening.

After the air is deflated, take the beads or screwdrivers. With the help of one we pick up the tire located near the nipple, and we drag it out, the screwdriver itself, attention, we leave inside. Do not be distracted, because you can break through the camera, be especially careful.

Now we take the second bead (screwdriver), and a little further from the nipple we pry the tire. Pull it out gently. So, step by step, making movements in a circle, you will remove the tire, be it a rim or a disc.

So, step by step

  • The rim brake opens, if any
  • We remove the damaged wheel, having previously unbuttoned and unscrewed the eccentric. Make sure that the unscrewed nut and the removed spring are not lost when falling
  • We lower the pressure in the chamber to the minimum
  • We stick a bead between the tire and the rim located on the side of the wheel. Side must be opposite to nipple
  • We release the border towards the center of the wheel and hook it onto the spoke, do not forget to do this, because this is a common mistake of novice cyclists
  • After 5-10 centimeters, repeat, but with a different border
  • Remove evenly, with both hands, finish near the nipple
  • Removing the camera
  • We remove the second bead of the tire. Do not forget to look and feel the tire, if there is any sharp object or pebble left there, which will ruin the next tire

Tools you should always have with you

Sideboards (side vanes, “assemblies”, “mounts”, in extreme cases, screwdrivers). Used to remove tires from the rim. This is a spatula made of plastic or metal, which has a hook for securing it to the knitting needle.

remove, rear, wheel, bicycle, disc

It is better if you have a set of 2-3 pieces, the speed at which the tire will be removed depends on this, because sometimes a girl can remove the tire with her hands, too, without straining, and sometimes a set of three will make you make an effort.

Camera patches. Now such kits are used that the problem will be fixed in a very short time. Can be self-adhesive.

Rubber or special “Bicycle” glue. Take it better, as super glues do not work at low temperature conditions.

Emery paper, required when cleaning at the puncture site.

Any aggressive liquid (such as gasoline) for degreasing the cleaned area. Do not take acetone, the combination of glue and acetone will give an unexpected effect.

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 site of damage 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, it should be dried later.

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 hold the camera to your ear and listen. You need to hear a hiss coming out of the damage.

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 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. Occasionally there will be a double puncture with the same object, so look at both the top and the inside of the camera.

Bicycle camera repair

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 together with force.

In this case, the main thing is strength, 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 finished, 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 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 reinstall the camera.

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.

INSTALLING THE CAMERA IN PLACE

Inflate the camera a little to avoid damaging it again.

Insert the nipple into a special hole in the rim and carefully insert the entire tube into the middle of the tire.

Tuck the edges of the tire over the entire width of the wheel into the rim. It should be possible to do this with your hands, but if the edges do not want to fall into place in any way, take the editing and use it to complete your plan. Do this carefully, otherwise you will have a new puncture.

In order for the camera to be able to straighten inside, pump up the wheel a little and knead the camera, this will be enough for the camera to take the correct position.

Bleed the wheel to the required state. To do this correctly, without fear that the wheel will burst unexpectedly, after inflation, squeeze the camera with two fingers. If your fingers cannot overcome resistance, then the camera is pumped up enough, you can hit the road.

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 the 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 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, this means the rim brakes.

It happens that it seems as if the chain is twisted or is not properly placed on the sprockets, 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 desired.

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.

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.

  • 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.
  • 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, about 40 pounds of pressure apply to end 5 “key.

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.

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.

  • 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.
    • 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, about 40 pounds of pressure apply to end 5 “key.

    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 gear, if applicable. sticky or dry.

    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.

    Remove the rear wheel of a bicycle with disc brakes

    Some novice cyclists ask the question of how to remove a wheel from a bicycle. over, difficulties arise, as a rule, with the rear wheel. Quite often you can hear similar phrases: “Oh, I’m afraid to take off the rear wheel, there are so many things screwed up, screwed up, I will never put it back on and I’ll definitely break something. I’ll go to the service center better.” Of course, you can do this, but than spending your time and money many times for going to bike repair, it is easier to just figure out how to do this operation yourself, especially since such a need may arise somewhere in the forest outside the city, and a bicycle workshop there it will definitely not be found.

    How to remove the front wheel?

      At the first stage, we look at what brakes your bike has. If you have disc brakes, then go directly to step 2. If your bike has a rim brake, then you need to release it. This procedure is approximately the same for all types of rim brakes. For example, to release a V-brake, you need to squeeze the pads with your hands (this is easier to do at the place where the cable is attached to them) and pull out the arc, as shown in the figure.

    Now carefully turn the bike upside down. In this case, it turns out that he stands on the handlebars and saddle quite steadily. At this stage, you should carefully monitor so that the equipment attached to the handlebars (bike computer, bell, bike headlight, etc.) is not damaged. In addition, it is best to place a cloth under the gear selectors to avoid scratching them. If your bike has hydraulic disc brakes (a hose with brake fluid comes from the brake lever, and not a regular shirt with a cable), then it is not recommended to keep the bike upside down for a long time, in order to avoid air getting into the hydraulic line, since if this happens, you will need to pump brakes (although the process is not complicated, but rather laborious).

    Next, we look at how the wheel is fixed to you: is it an ordinary nut or an eccentric (a small lever).

    3.1. If your wheel is secured with a nut, then you need to take two suitable keys. Throw one on one side, the second. on the other, and turn one of the keys counterclockwise, holding the other in place. It is not necessary to unscrew the nuts all the way, but simply loosen until the wheel can be safely removed.

    3.2. If your wheel is fastened with an eccentric, then everything is generally simple. no tools needed. We pull this eccentric towards ourselves, as shown in the figure, after which it is necessary to unscrew it a little more counterclockwise, holding it on the back side with your hand until it becomes possible to pull out the wheel.

    At the last stage, simply pull the wheel up, and if you did everything correctly, it can be easily removed. On bicycles with disc brakes, do not press the brake lever with the wheel removed, as this may compress the pads and you will have to tinker with them too.

    Installing the front wheel

    As you perfectly understand, the process of installing the front wheel is the opposite of removing it and it makes no sense to describe it in detail.

    We put the wheel back, as it was. Do not confuse the direction of rotation of the wheel (written on the tire). Remember that your bike is overturned and it is worth considering the direction of travel. In the case of disc brakes, it is difficult to confuse, since it is necessary that the disc hits exactly between the pads.

    We tighten the nuts or tighten the eccentric

    If you have rim brakes, you need to return them to their original condition. We check that the wheel does not dangle, rotates freely and the brake functions, otherwise we check everything again point by point.

    How to remove the rear wheel?

    The rear wheel removal process is COMPLETELY the same as the front wheel removal process. You don’t even need to look at the equipment suspended from the back (you only have to remove the chain from the axle if it gets caught).

    Installing the rear wheel

    The installation process is also similar to installing the front wheel, with a few exceptions: it is necessary that the chain fits correctly. To do this, we bring the wheel to the attachment points, put the chain on the sprocket and then put the wheel in place. True, a situation may arise in which it will seem to you that the chain is twisted, and in order to unravel it, you will have to remove it. This is not true. You just need to twist it back and forth, imagine how it was installed before on the stars and most importantly. do not panic. That seems to be all. Now you have mastered the art of removing and installing wheels.
