How To Change A Tire On A Bicycle Rear Wheel

Replacing a bicycle 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, just unscrew the cap.

To remove the tires, you will need special mounting 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 begins to tighten, you need to pry the sides a little further, until a sufficient 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, not to use too much force. When the tire is removed, removing the damaged camera and installing 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, you must 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.

Installing the rear wheel

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

How To Change A Tire On A Bicycle Rear Wheel
  • Put the chain on the smallest sprocket, insert the wheel onto the frame mount. In this case, it is important to make sure that it has completely entered the grooves of the frame.
  • We fasten 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 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 small test drive to see how your bike will behave on the road after the updated.

Maintenance and diagnostics of the rear wheel is a mandatory procedure to keep the devices in good condition.

How to change the rear wheel on a bike

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, the parts begin to wear accelerated. If the wheel has not been serviced for a long time, the bearings may crumble altogether. To get access to the bearings of the hub, you will need to temporarily get rid of the rear sprockets.

The reverse gear is removed using a puller and the 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 is held by a 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, which are installed on top, carefully fold them to the side along with the washers, and then removing the same cassette.

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 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 replacement of the bushing is required if the bearings have become unusable. However, often when the bushing is stuck in a normal state, it is enough to change the bearings. Often, both will still serve faithfully if they are well lubricated. Correct 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 need to be adjusted by returning them to a straight position. However, during the backlash, the part is already faulty, so the best option would be to replace.

Removing the sleeve

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

Before disassembling the sleeve, 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 the cleaning and lubrication of 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 the whip is tightened.

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.

The main components of the wheel

A standard bicycle wheel consists of several main parts:

  • The bushing is the central part, through which the torque is provided. The interior of the rear hub is slightly more complex than the front. NOT every sleeve can be disassembled at home, some variations without special equipment and knowledge It is better not to touch. 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 you need to repair the rear wheel of a bicycle or it is just time to service the spare parts, you need to clarify the procedure to be carried out when removing a wheel.

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 does NOT specialize in 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 and chain.

Usually, one wrench of the appropriate size is enough, with which the nuts are removed one by one. If the bushing is turning, then the nuts are unrolled 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.

Camera replacement

First of all, you need to deflate the wheel. Unscrew the cap and press the nipple to deflate the air. If there is no damage chamber and there is no air in it, simply remove the cap. To remove the tires, you need mounting paddles, which will be convenient for prying the camera until it becomes easy to pull it off the rim.

The camera can be replaced without 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.

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.

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 and do not get hurt by 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 tires / tube as needed. If you bought a new camera, unfold it, remove the plastic cap and retaining ring.

Place a new tube on the tires; Make sure you DO NOT 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 tires on each side in turn. This is NOT an easy process, 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 tires in order not to put on the tires 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 precautions:

  • Make sure that there are no hot objects near the camera. Heat increases pressure inside the chamber, which could cause it to explode!
  • Before inflating the chamber with air or placing it in tires, it can be sprinkled with talcum powder.

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

Remove 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 have nuts. They are equipped with a special quick release mechanism, which 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 get the brake cable out of the brake lever connector. Some brake systems need 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 are removing the rear wheel, you will need to remove the chain from the sprocket (if you switch to lower gears, it will be easier to remove the chain). The front wheel is slightly easier to remove.

Fully deflate the wheel, pressed the valve into the nipple. If the wheel has a French valve (presta valve), you need to Unscrew the upper part of the rod to release the air. At this stage, 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 tires and walk around the entire circumference of the rim. Compression will help release the air. Also, by compressing the tire around the rim, it will be easier to remove.

The information provided on the website on how to use the WD-40 was provided to the manufacturer of the WD-40 by the end users of the product. These applications have NOT been tested directly by WD-40. Therefore, it is NOT a recommendation for use from WD-40. Always follow the directions for use and heed the warnings printed on the product packaging.

Dismantling sequence

To begin with, 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.

Upside-down bike

  • Turning 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 make it easier to remove the wheel;
  • V-type rim brakes must first be released and removed, otherwise further wheel dismantling will no longer be possible. (It is not difficult to release the brakes, for this you need to move the cable towards 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).
  • Then we act depending on the type of fastening of the rear wheel to the bike. 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.

Carefully remove the chain from the sprockets

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

Installing the front and rear wheel

Quick release

The eccentric mechanism for fixing the axles of the wheels uses a hollow bushing equipped with a shaft, a lever, which works as a cam mechanism, and an adjusting nut. The cam creates tension on the shaft and pulls, and press the adjusting nut firmly against the lining 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 securing the wheel axles and cam. 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.

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 upright without a rear wheel, as this could damage the rear derailleur.

1. 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.

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

Note: With disc brakes, decoupling pads are not required. 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 specially designed spacers such as PP-1.2 if needed.

3. Disconnect 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 here: some functions are similar to the axle of the eccentric mechanism for securing the axles of the wheels. pull the lever outward to disconnect and turn to loosen. Some straight wasps are equipped with a special device that should weaken here. However, other simple levers that are needed to loosen or tighten are not used.
  • Solid here: on the wheel axle with nuts, both nuts must be loosened from the outside.

4. On the front wheel. just point the wheel down and out of the fork. For the rear wheels, pull the rear derailleur so the screws clear the chain. Lower the wheel, pushing it 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 thanks to which the wheel can be easily removed.

  • To engage the SRAM shift mechanism Move the lower roller forward to loosen the chain and press the button to lock it in place.

  • Removing and installing bicycle wheels

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

    How to remove the front and rear wheel on a bicycle

    Removing the front and rear wheels requires almost the same steps. Despite the fact that much more equipment is installed on the rear wheel, there will be no significant differences here.

    • Follow the steps below, depending on the type of brake installed on your bike. For the rim brake system, it will be necessary to unclamp the brake pads so that they do NOT interfere with the removal of the wheel. In the case of a V-brake rim system, you need to compress the pads and pull out the archwire. You can do without unclenching the pads, for example, deflating a wheel. If your bike is equipped with a disc brake, go to the next step.
    • Turning the bike over with the saddle and handlebars on the ground. In this position, it will be most convenient to remove and install the wheel. This should be done carefully enough so as not to damage the equipment mounted on the handlebar and NOT to scratch the gearshifts with the saddle. Bicycles equipped with hydraulic brakes should not be kept upside down for extended periods. In this position, there is a possibility of air entering the system, which will lead to a deterioration in braking performance; to eliminate this problem, you will need to bleed the brakes.
    • Now you can unscrew the nut holding the wheel to the frame. There are two types of nuts. an eccentric nut or a regular nut. The eccentric is a lever that securely fixes the wheel in the extreme position away from itself. Accordingly, we bend the eccentric towards ourselves, then weaken it so that it will be possible to remove the wheel. An ordinary nut should be unscrewed with two keys, or with a second suitable tool. The nut can only be loosened, to a state where it will be possible to remove the wheel.
    • When removing the rear wheel, the only problem that can arise is the chain. If it snags. Remove it from the axle. The rest of the attachments do not need to be touched.
    • Now you can remove the wheel by simply pulling it up. For bicycles with disc brakes, do not apply the brake without a wheel installed. If you do this, the pads will compress, and until you open them, the wheel will not put back on.

    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 apply significant axle pressure. Disc brake systems are fork-mounted and apply a load to the rotor, which is attached to the hub.

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

    Wheel installation

    Wheels Must be properly mounted 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 lining. 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 grooves 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, it should be completely in the pad on the frame.

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

    2. Place the wheel in the skid on the frame. Make sure the hub is fully seated in the frame or fork.

    • On the rear wheel, turn the gear back first and place the smallest gear between the top and bottom of the chain. Place the wheel between the brake pads, hooking the smallest gears on the chain.

    3. Tighten the wheel:

    • Cam mechanism for securing the axles of the wheels: Tighten so that the lever meets resistance 90 ° from the frame or fork.
    • Straight here: move here in place and turn clockwise until it stops.
    • Solid here: Tighten both axle nuts 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 lbs of pressure to the end of a 5 “wrench.

    4. Determine the end position of the lever closing. Rotate the front arm and adjusting nut so that the arm ends up only at the front of the fork. Place the rear arm between the chain support and the seat. Stopped the lever as needed unless it is fully closed.

    5. Re-remove the brake mechanism if applicable.

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

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

    Solid here

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