How to mount an axle to the rear wheel of a bicycle

How to change the rear wheel on a speed bike

Carrying out a spring revision of my old high-speed bike, we found an “eight” on the rear wheel. a change in its geometry. The rim was bent so much that it constantly touched the brake pads, making it impossible to drive safely.

First we decided to tighten the knitting needles. There are special ways to do this at home. For those who are interested, it is enough to search the Internet for how to fix the G8. A closer inspection revealed that a pair of spokes was missing. The plastic spoke guard installed on the wheel makes it difficult to install new ones, so it must be completely disassembled.

Turn the bike upside down, unscrew the eccentric clamp nut, remove the eccentric itself from the hole in the axle, release the footrest, remove the chain and wheel. In this case, you need to loosen the brake pads and release air from the wheel so that the tire does not cling to them.

Unscrew the nipple, pull out one side of the tire, gently prying it with a flat screwdriver, without tearing the camera. Take out the camera, then remove the tire.

Now you need to remove the asterisk. It is impossible to do this without a special puller, so we took care of its purchase in advance.

Inserts the puller inside the sprocket and unscrew it with a gas wrench. By the way, for these purposes, any key for 24.

Our speed bike had a single rim wheel. Almost all modern bikes are equipped with double rim wheels. It is believed that they are stronger and more reliable. The difference in price is not very big, so we listened to the seller and bought a copy with a double rim.

At first, the plan for replacing the rear wheel on a speed bike seemed simple: screw the sprocket onto a new one, insert the tube, insert the tire, and mount it on the bike. But upon closer inspection, it turned out that the wheel axles are different. The old one. with a hole inside for the eccentric, and the new one. without it.

Therefore, I had to rearrange the axle from the old wheel to the new one. This requires 2 keys. We hold the locknut with one, and unscrew the other with the other. Having unscrewed, remove the washer and unscrew the locknut, which is the bearing boot. While loosening the nut, watch out for balls that may fall out of the gap formed. Now you can remove the axle.

How To Use And Adjust Thru Axles On Your Road Bike

In the same way, we remove the axle from the new wheel. The grease in it is fresh, thick, so the bearing balls, sticking to it, were in their place.

Carefully, adding fresh grease, insert the axle with a hole for the eccentric onto the new wheel and tighten the nuts in the reverse order.

It is necessary to tighten the nuts with a cone for the bearing until there is no play in the carriage, but at the same time the wheel rotates freely. On both sides of the axle along the edges, we leave a space equal to 1 cm so that it fits into the eyes of the rear fork of the bicycle. This distance is adjusted with a bushing washer. Tightening the second nut, we fix the first with a key so that it does not move, otherwise the wheel will spin with effort.

Then we collect everything in the reverse order. We install the protection of the spokes, with the help of a puller we twist the asterisk.

On the one hand, fill the tire, insert the camera, fill the tire completely. We pump the chamber with a pump, then bleed the air so that it fits into place.

Now we take the wheel, put the chain on the sprocket and install the axle in the fork eyes. The tire, having pressed on it, must be pushed between the brake pads.

Install the footrest, insert the eccentric clip and secure it with a nut.

Let’s adjust the brakes by fixing the pads near the rim. We pump up the camera and make a test drive. This completes the replacement of the rear wheel of the sports bike. If you liked the article, share it on social networks.

Removing the front wheel from the fork

Removing a wheel is the simplest maintenance procedure for your bike. This is done very simply:

  • Turn the bike upside down.
  • Release the rim brake, remove the caliper from the disc.
  • Loosen the fasteners from the fork dropouts.
  • Remove the wheel axle from the mountings.

On dropouts, the mount is nut and eccentric. In the first case, you will need two 15 mm wrenches. we hold the nut with one, and gently twist the other on the opposite side. With the eccentric, everything is easier. loosen the retaining nut and fold the clamping lever.

Renovation work

Before you start disassembling and assembling the rear wheel of a high-speed bike, you need to find a comfortable place, stock up on gloves so as not to get your hands dirty. If there is no relevant experience, you should strictly follow the sequence of actions, take into account all the subtleties. A great help in this matter. training videos.

Installing the front wheel.

The front wheel is installed in the reverse order of removal. The most important thing is to correctly set the force with which the eccentric clamp holds the wheel in the fork. Overtightening is undesirable. either the clamp or the plug can be damaged. Too little force can cause the wheel to fall out of the fork (this is especially true for bicycles with disc brakes, because they exert significantly more forces on the fork than rim brakes).

How to Quickly Remove the 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 can 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.

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 also 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 roof of the car. Then it is more convenient to disassemble the vehicle into parts in order to transport it in the trunk or in the 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 service skills at the same time.

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

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

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 an ordinary 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 tighten, 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.

From above, the outer part of the tire is put on the rim, this time from the side of the nipple. When installing the tire, the correct direction of the tread pattern must be taken into account. 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.

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.

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 squeaking 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 reverse gear 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 knocked 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, the spokes must be unscrewed enough to easily pull it out of the engagement.

Bike Maintenance: How to Remove a Rear Wheel with a Thru Axle

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.

Typically, MTB bicycles and bicycles with disc brakes use a 12mm axle.

Which axle to mount on the rear wheel to use my bike with a bike rack?

If you bought a bike rack for the rear wheel, then you should know which axle is installed on the bike.

As we said earlier in our article “Learn to distinguish between the axles of a bicycle“, the traditional QR axle is 9 mm from the 12 mm axle.

What should I do if my bike uses a thru-axle?

If your bike uses a thru axle, you should check the axle diameter, it is usually 12mm, you should measure the axle and the thread pitch.

The following video from The Project Robert Axle, an axle manufacturer for major bike and bike brands, explains how to measure an axle. Contact us if you need a ruler to measure the axis, (English video, remember you can turn on Russian subtitles).

Axles 12 mm.

Bike stands usually include the traditional QR axle on all bike stands, and some Direct Drive bikes also come with 12mm axles or adapters.
