How to assemble the front wheel of a bike

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 (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 other on the other, and twist 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 are 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.

Disc brakes

Bicycles 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.

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.

How to install quick release front wheel on bicycle

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.

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, the spokes must be unscrewed enough to easily pull it out of the engagement.

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

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.

Removing the sleeve

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

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

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

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

Dismantling sequence

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

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

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

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, 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 the axle nut, 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.

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

  • On the rear wheel, first turn the gear back and place the smallest gear between the top and bottom of the chain. Place the wheel between the brake pads, hooking the smallest gear on the chain.
  • Cam mechanism for securing the axles of the wheels: tighten the axle so that 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 the end of the 5 wrench.

Determine the end position of the lever closing. Rotate the front arm and adjusting nut so that the arm ends up just at the front of the fork. Place the rear arm between the chain support and the 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.

Solid axis

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

Three of these plates are enough for me so that one side of the tire begins to easily climb out of the rim. When instead of plastic plates I used keys, screwdrivers, or any other materials at hand, I very often punched a new camera when installing.

Next, we take out the old camera, starting with the nipple, after unscrewing the cap and washer.

Now we carefully unpack the new camera without violating its integrity. I stopped gluing old cameras a long time ago. As a rule, it takes longer and more expensive.

Before shoving a new tube into the tire, you should swing it a little so that it takes shape and we have less chance of chewing it between the rim and the tire.

READ  Where can you learn to ride a bike

First of all, insert the nipple and secure it well with a washer. Next, with our hands we push the camera under the tire along the entire perimeter.

Now we feed the tire back into the rim, first with our hands, and at the end with the same plates that we took out. At this stage, you need to exercise the utmost care, as it is at this point that you can damage the camera.

After the tire is in place, you need to lightly tap the wheel on the ground, turn it in a circle. Thus, the camera will take its place where it could get between the tire and the rim.

Install the wheel into the fork. Tighten the nuts alternately on both sides, while making sure that the distance between the fork and the wheel, closer to the frame, is approximately the same. If you are changing the camera on the rear wheel, be sure to put on the chain when installing.

Having installed the wheel, turn it by hand, if it turns a little more by inertia, then everything is in order, you can pump it up, if it stops almost immediately, then you need to unscrew it and release the fixing nuts on the bushing a little.

If I am not in a hurry and do everything in order, then it takes me no more than 15 minutes to replace the camera.

Removing / installing the front wheel on a bicycle is one of the simplest tasks a cyclist may need. Usually, the front wheel is removed for transport or storage of the bike, but there are also situations when you need to remove the wheel in order to glue the camera or change the tire.

How to remove the front wheel?

If you have disc brakes, the task is even easier, but remember to insert a spacer between the brake pads because during transportation or repairs, you may accidentally press the brake, the pads will compress and complicate the installation procedure, especially if the brakes are hydraulic.

In order to remove a wheel from a bicycle with rim brakes, you need to unfasten the pads or lower the front wheel.

To unfasten, disconnect the pads, you need to press them to the rim with your hands at the junction of the cable, and pull the arc so that it crawls out of the groove.

Unscrew, remove the wheel.

After you have dealt with the brakes, proceed to removal. The wheel can be attached to the fork in two ways:

1) With a bolt. then you need a spanner or spanner of the desired size (usually from 13 to 17 sizes, but most often 14 or 15 sizes). Bolted connection is now found on children, teenagers, and also cheap bicycles.

2) Quick release. eccentric connection. Most common these days. Removal / installation of the wheel becomes possible even without the use of special tools. To remove the wheel, simply move the position of the eccentric clamp to the opposite side and hold it with your hand, make a couple of turns of the thumbscrew until you feel that the wheel moves easily.

City Bikes- Installing Your Front Wheel

The installation process is the opposite of removing.

1) Be sure to check the direction of the rubber when installing (compare with the rear wheel).

2) Do not pinch the eccentric when you press the eccentric handle, it should lower without much effort, but also check that the wheel does not wobble.

3) Check the center of the wheel, rotate it several times and apply the front brake, the wheel should not rub against the pads.

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.

Useful to pay attention

If you have never done something, then you may think that it is 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. In short, we have already 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 a bicycle consist 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 deflate a little air from the tubes. Now turn the bike upside down (if you have any accessories installed on your handlebars that can 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 hydraulic 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, 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 second counterclockwise.

How to remove wheels from a bicycle with disc brakes

READ  How to choose a bicycle rear wheel hub

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.

The 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.

Are you ashamed to contact the service in order to easily put the wheel on the bike? It’s time to learn to leave this disposition on your own. Plus, save time and money.

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. with one we hold the nut, with the other we carefully twist it on the opposite side. With the eccentric, everything is easier. loosen the retaining nut and fold the clamping lever.

  • replacement of tubes / tires;
  • tightening / loosening of the spokes;
  • bulkhead bushing;
  • rim painting.

Installing the front wheel on the fork is done in reverse order.

Replacing the camera

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

assemble, front, wheel, bike

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

Instructions

Insert the wheel into the fork ends and adjust the eccentric clamping force with which it will hold it in the fork. Do not overtighten as this may damage the clip or plug. If the tightening is too loose, the wheel can fall out of the fork only if your bike does not have disc brakes, because they put a lot of stress on the fork than rim brakes.

Make sure the wheel is in a symmetrical position without any misalignment on the fork tips. If the wheel is centered correctly, that is, without eights and an umbrella, and the fork is not bent at the same time, then the wheel itself will definitely stand upright. Otherwise, find the cause of the skew and fix it.

Make sure the wheel axle fits snugly into the groove in the fork tip. The axis should lie at the very bottom of the groove.

If your bike does not have hydraulic disc brakes installed, carefully insert the brake disc between the brake pads into the caliper while installing the wheel. If the distance between the pads is too small, and it is not possible to insert a disc between them, in this case, carefully move the pads of a wide screwdriver or something like it. Do not apply large efforts so that no burrs remain on the brake pads.

Rotate the eccentric clamp lever 90 degrees so that it is approximately parallel to the hub axis. Later on, tighten the wing nut as far as it will go, but do not tighten it.

Now turn the cam lock lever so that it is parallel to the fork. At the same time, make sure that the effort is tangible, but not prohibitively strong. If necessary, turn the wing nut to increase or decrease the compression level.

The wheel is installed. If your bike does not have V-Brakes, remember to fasten them.
