Learning to bead a wheel and glue a hole in a tire. How to install the wheel and tighten the mount

For most beginners, the question of how to change the tube in a bicycle wheel arises only after the first puncture and causes concern. In fact, it is one of the most simple processes in bike maintenance if you have the right tools and some experience.

For an active cyclist, a puncture is a common thing, because on the roads you can constantly find broken glass, pieces of wire and other pieces of iron. Often punctures also occur when riding over rough terrain, especially if low-quality rubber is installed on the bike.

Required Tools

If during walks you often drive far from home, then you should have with you the minimum set of tools that you will need to replace the camera in the field.

Bicycle mounts - plastic or metal mounts greatly simplify the wheel beading. Of course, you can use improvised tools, but this is not very convenient and increases the risk of damage to the camera and even the rim.
Pump - without it, of course, you can change the camera, but you won’t be able to leave on a flat tire.))
Spare camera.
Bicycle first aid kit - a set of patches and glue for repairing a punctured tube.

It is important to keep in mind that more than one puncture can happen on a hike, and you can’t get enough cameras for all cases, so it’s better to have a first-aid kit with you. The repair kit includes glue, patches and detailed instructions.

How to remove the camera from the wheel

If a puncture does happen, then to replace the tube, you must first remove the wheel from the bike, and then disassemble the tire to pull out the tubes. This process is quite simple if you have bicycle mounts with you.

First you need to bleed the air from the chamber to the end, if this did not happen during the puncture. Then we insert one of the mounts between the tire and the rim, then we hook the edge of the tire with it so that it crawls out of the rim.

Then, next to the first montage, we perform the same operation with the second montage. Next, we carry out the second installation along the rim, pulling the edge of the tire outward. If necessary, you can use a third installation.

After one edge of the tire is disassembled, you can pull out the camera. First you need to pull out the air valve (nipple), and then the entire chamber.

How to put a camera on a wheel

Before proceeding with the installation of a new (or sealed) tube on the wheel rim, you need to carefully check the inside of the tire. After the puncture, pieces of what led to the puncture could remain, and later, may lead to a second puncture. Do this carefully so that you can get hurt. Then it is necessary to check the integrity of the protective gasket that protects the chamber from protruding spoke nipples and the valve hole.

The put on camera should be slightly inflated, so it will be more convenient to insert it into the tire. The procedure for installing the camera in place is the reverse of removing it. However, it is much easier to bead the tire onto the rim and you can often do without rigging and do it with your bare hands.

With the tube in place and the tire in place, you can inflate the wheel, adjusting the tire in the process so that its edges are evenly positioned on the rim. Put the wheel back on and you're good to go!

That, in general, is all that can be told about how to replace the camera on a bicycle wheel. If you have something to add, you can do it in the comment block below!

Many men do not want to waste their precious time. This is manifested in the rejection of walking, replacing walking by riding a bicycle, scooter, motorcycle and other means of transportation. This significantly reduces the time, but having decided on this step, you must be prepared for certain situations awaiting you. I'm talking about a tire puncture. If this happens, then it is impossible to continue moving. So that you do not remain stationary for a long time, today we will talk about how to replace the camera on your bike or motorcycle, as well as how to properly seal the camera of your vehicle.

I want to advise you always to carry various tools with you, in general, any driver should know this, but many neglect this recommendation, and therefore get into difficult situations.

Wheel alignment and disassembly

I will try to paint all sorts of details to make it easier for you to achieve the final result.

Wheel stripping is the process of removing a tire from a rim or rim to replace or repair a tube. For this process, you will have to resort to, since we will need flanges, although if they are absent, you can safely use screwdrivers.

Now you can start disassembly:

We remove the wheel. Depending on the type of vehicle, the method of removal may vary. I think you can figure this out for yourself.
We drop the wheel. To do this, take the cap screwed onto the nipple of the tire, turn it over with the back side, insert it into the nipple and unscrew it. When you perform this process, you will hear the characteristic sound of air deflation
If you are beading a motorcycle wheel, you will have to use the motorcycle footboard. Place the removed wheel under the leg and press the wheel to move it off the court. Until you do this, the disassembly process cannot be continued. In the case of a bicycle wheel, this is not necessary, this type of wheel is easier to disassemble.
Now we take the sides (or screwdrivers), one of them we hook the tire near the nipple, and pull it out without pulling out the screwdriver itself. Be extremely careful not to hit or damage the camera. Next, with the second beading, slightly stepping back from the nipple, we hook the tire and pull it out. Thus, moving in a circle, you will remove the tire from the rim or disc.

What is the process of boarding:

You reinsert the nipple, sealed or replaced, of the bladder into the disc or rim with the tire pre-fitted.
Insert the tire from the opposite side of the nipple into the rim and, using the bead, begin to set the tire into the rim in a semicircle. I want to draw your attention to the fact that some tires have a direction of movement, this can be determined by the corresponding inscriptions on the sides or by the pattern of the spikes themselves. When inserting a tire, you must insert it according to the direction of rotation of the rim.
When the tire is fully set, we fix the nipple, screw in the nipple and inflate the wheel. That's it, your wheel is now ready for further use.

Well, we learned how to do this procedure, but why do we need it. About it will be discussed below.

How to properly seal the camera

Voi is for this we need to get to the camera. If it releases air on its own, most likely a puncture has occurred and it needs to be sealed. To do this, we need a repair kit for punctured wheels. You can buy one in any automotive or bicycle market.

Let's go directly to the repair process:

Pump some air into the chamber and lower it into the water. If you press it in the water, then the hole will instantly make itself felt, as the air will begin to escape through the hole, and you will see bubbles rushing out. Thus, we have determined where the hole in the wheel is.
Now we wipe our camera from water. We clean the place of the hole with sandpaper.
We apply glue from the repair kit to the place where the patch will be attached.
We remove the sticker from the patch and also smear it all with glue.
After that, we apply the patch to the breakdown site, smooth it and place it under the press for a while. This is necessary so that there is no air left between the tire and the patch.
When the glue dries, then the tire should be pumped up, it should not be flattened.
After all this, we release the air, and start reading this article from the very beginning in order to master the process of beading.

That's it, now you have the basic knowledge. And what exactly? You have learned how to disassemble a wheel and how to seal the inner tube of a bicycle and other vehicles. But the main thing that you should have learned is that you should always have spanners, screwdrivers and a wheel repair kit.

Everything, now you can safely finish reading the article. See you next time.

The most common reason for the impossibility of further movement on a bicycle is such an annoying, but inevitable thing with regular cycling, like a puncture. Well, if it happens near the bike shop. But bicycle paths are inscrutable, and workshops are not located at every step.

So every lover active rest you just have to be ready to deal with the problem. Moreover, it is not at all difficult to solve it. Dismantling the wheel and repairing the camera is not a tricky business.

Wheel disassembly

First, what needs to be done for disassembly and repair is to remove the wheel from the bike. If he has disc brakes, then everything is simple. The eccentric is untwisted, the wheel is removed. In the case of v-brakes, you must first release the brake, and only then unscrew the eccentric and pull out the wheel;
Second. Release the remaining air from the chamber. To do this, just press on the nipple stem, and the air will come out by itself. Naturally, after unscrewing the nipple cap.
Third. It is necessary to pry off the side of the chamber with a mounting spatula, and carefully moving it along the rim, disassemble the wheel on one side. Everything, access to the camera is received.
Fourth.To pull out the chamber with the schrader system nipple (or car), you just need to pull it out. The chamber of the Presta system is additionally fastened with a nut, which is easily unscrewed by hand.

Camera repair after damage

So, in the hands of the camera, next to the disassembled wheel. What to do next? And then you need to find a puncture. To do this, the camera must be pumped up. It will not work, there is a hole in it. That's just the air coming out of the hole and its hissing will help to find the source of the problem. Wonderful. When the hole is found, you need to get glue and patches from the first-aid kit. And a small piece of sandpaper or a “grater”, in each first-aid kit in different ways.

Be sure to clean the puncture site, then apply a thin layer of glue. And let it dry for 5-15 minutes (the exact time is written on the glue package). After the glue dries, attach the patch to the hole and press firmly. It is not the time that matters, but which patch is pressed, namely the pressing force. The stronger, the better.

While the glue dries, do not waste time. Something pierced the chamber, and this “something” is probably still sticking out in the tire. From within. A thorough inspection of the internal and external surfaces tires. If the look does not reveal anything, you must very carefully run your hand along the inside of the tire.

Sometimes a foreign body can be so small that it is almost impossible to notice it visually. However, you need to look for it with your fingers very slowly and very carefully, observing all precautions.

After the puncture is closed, foreign objects from the internal inside the tires are removed (or there is a certainty that they are not there), you can proceed with the wheel beading.

Wheel bead

Insert the nipple into the hole in the rim. If this is a Presta nipple, then do not forget to tighten the nut. Spread the tube between the tire and rim.
Slightly pump up the camera. This will allow, when beading, to avoid its getting between the rim and the mounting blade.
Bead the tire with your hands, as much as possible. As a rule, modern tires allow you to do without an additional tool when beading, but this rule does not always work. In some cases, you still have to fill the tire into the rim with the help of shoulder blades.
Insert the assembled wheel into place. Screw the eccentric. In the case of a V-brak, do not forget to fasten it back. In the case of a disc brake, a small unpleasant surprise may await. Removing the wheel can change the distance between the disc and the pads and interfere with the alignment. Most often, this violation is not critical, but still, further minor adjustment of the brakes may be required.
Bring the pressure in the chamber to the required level. Waiting for the glue to dry is not required, since the pressure of the chamber to the tire acts as a press.

That's it, the bike is cured, the puncture is patched up. You can go further.

Tubeless wheel repair

If the bike has a tubeless wheel, things are a little more complicated. It is unlikely that it will be possible to repair it in the "field" conditions, so they take a camera on long trips. In case of problems, a tubeless wheel is made “chamber”. But at home, it is quite possible to carry out an independent repair of the “tubeless” one.

If you need to put the tire on the wheel without using the camera, then:

Rim tape is glued on.
If the tire is new, then it is necessary to give it the correct shape. To do this, the wheel is assembled in a “chamber” version and for one day it rests in this form. A day later, the camera one side of the tire is disassembled and the camera is removed.
The nipple is inserted and fixed.
Sealant is poured inside the wheel. Usually, one wheel requires from 50 to 100 grams.
The wheel is beaded and inflated. At this stage, it is very important to use a sufficiently powerful pump. Precisely because hand pumps cannot generate high pressure, it is difficult to repair a tubeless wheel in the "field" conditions.
After the wheel is inflated, you need to shake it, twist it. So that the sealant is distributed over the entire surface and closes the smallest holes.

The main advantage of tubeless wheels is their low weight and resistance to snakebite punctures. However, this comes at the cost of greater maintenance complexity and lower allowable pressure.

Necessary tools for boarding / stripping

For wheel beading, it is recommended to use mounting blades. They are made from either plastic or metal. The rounded edges of the blades make it impossible to damage the rim or tire. The bend of the mounting tabs makes it easy to pick up the rim when disassembling, and just as easy to put the rim back into place when reversing.

In the absence of blades, you will have to use improvised means. However, this greatly increases the risk of damage to bicycle parts. In fairness, it must be said that in most cases, beading can be done without the use of a tool. However, these do not always work out, so there should be montages.

Bicycle wheels are mounted on the frame: the front wheels are on the fork dropouts, the rear wheels are on the chainstay dropouts. Repair, cleaning and lubrication may require their removal. There is no need to bring the bike to the service for this occasion, since everyone can remove the wheel from the bike right at home.

Why do you need to remove the wheels? As a rule, these are bushing bulkheads, spoke and rim repairs, bike cleaning and the notorious tire change.

Removing the front wheel with rim brakes

Before proceeding with the removal of the wheel, the bike must be put "upside down" on the saddle and handlebars. Previously, all accessories - mirrors, headlights, a bell, decor elements - should be removed so as not to interfere with work and simply not to damage them. It is advisable to put under sensitive shifters soft tissue so as not to damage them under the weight of the bike.

In short, the front wheel is removed according to the scheme:

Release rim brakes.
Loosen the attachment to the dropouts.
Carefully remove the axle from the legs.

It is necessary to release the brakes in order to easily pull out the wheel and not damage the system. To do this, compress the connecting arc and unscrew its fastening with a hex wrench. Now the brakes are free. An alternative option is to remove the pads from the brake mechanism, however, after assembling the wheel, they will have to be adjusted again.

This is how v-brakes open

Mounting wheels on a bicycle is presented in two versions - nuts for 15 and an eccentric. To remove the axle from the dropouts on the nuts, you will need two keys - one will act as a worker, and the other as a lock. Unscrew one nut counterclockwise while holding the opposite one.

What can be used? Traditional open-end or box wrenches. The second option is even more convenient and easier to grab the nut. Adjustable wrenches with wide lips are not recommended for work, as they can “eat” the corners of the nuts.

It is much easier with an eccentric - loosen the bolt and lift the locking lever. If the spring is not sufficiently weakened and the lever does not rise completely, unscrew the bolt harder. Actually, removing the wheel at home is as easy as shelling pears.

In this section, the topic of removing with V-brakes was touched upon. It’s even easier with discs, but with single speeds with a foot drum on rear hub and even more so. For disk brake system with hydraulics, there is one limitation - do not keep the bike upside down for too long, as the tubes become airy. That is, the wheel was removed and the bike was returned to its normal state for the duration of the repair or other manipulations.

Dismantling and installation of tires

A tire breakdown on the go is an unpleasant phenomenon that can occur anywhere. It can even go down at home. You can’t ride, you have to, a tire or all together. You can contact the service for a solution to the problem, but in addition to money for a new consumable, they will also take work. And why spend extra money and strain the master when all the manipulations for removing and installing tires can be done on your own? Consider how to disassemble a bicycle wheel and assemble a tire. You will also have to remove the tires and put them back on when straightening the rim or replacing the spokes.

For work, you will need special plastic crowbars or two small shoe spoons. It is undesirable to use screwdrivers, as they can damage the rim.

How to disassemble the wheel:

Fully deflate the tire (if it is being removed for rim repair, not replacement).
From the side opposite to the nipple, pry off the bead of the tire with pryers and fasten them to the spokes. The distance between the shoulder blades is at least 20 cm. With the third assembly, pick up the bead in the middle and pull it out of the rim.
Remove the mounts and pull the tire off the wheel. If there are only two shoulder blades, we fix one, and draw the other along the board, removing it outward.
Pull the nipple out of the mounting hole. On some models, it can be attached with an additional nut, then we twist it.

Now that you have a new set or the wheel has been repaired, you need to put the tire back on, or bead it:

Pump the chamber up to 0.5 atm so that it takes a rounded shape and does not break.
Insert the nipple into the hole, the chamber on the surface of the rim. It is important that it exactly matches the size of the wheel.
Compress the tire beads and insert from the side of the nipple.
Sequentially distribute the edges around the entire circumference with your hands.
On the opposite side, it will take effort to push the bead in.
Inflate the tire to the desired pressure and put the wheel on the bike.

It's so easy to wheel the wheel with your own hands.

How to install the wheel and tighten the mount

The process of installation in its rightful place is strictly opposite to dismantling:

Insert the axle into the dropouts, taking into account the direction of rotation "forward".
Adjust position (for rear).
Tighten nuts or eccentric.

Wheels are put on a bicycle only with tires, otherwise it will not work to put the tires on the rims. "Forward" on an inverted bike - back, look at the top. The arrow, paws and other indicators should point in this direction.

On rear dropouts, the position of the axle relative to the chainring can fluctuate, and its remoteness affects the chain tension. The optimal position is recommended by the manufacturer, “all the way”. It should be noted that the adjustment rear wheel dropout is valid for models with one gear and bikes with a planetary gear.

Nut tightening. Sometimes the mounts are equipped with additional washers-stoppers against scrolling the axis. If the manufacturer provided for this, we must install them. Next, the nuts on both sides are slipped on manually. Again we take two keys: on one side the nut is fixed, on the other hand it is twisted. Then go to the other side and tighten the mount until it stops. The technical passport for the bike indicates the tightening torques for the fasteners. Following these guidelines will ensure uniform force distribution and optimum geometric integrity.

Wrench with dynamometer for determining tightening torques

Eccentric fixation:

Install the axle in the dropouts.
Turn the bolt clockwise.
Press the lever and fix the eccentric.

The locking lever should go with some effort and freely lower to the end. If it folds too easily, you need to tighten the bolt, if it does not fall, loosen it.

The wheel removal procedure is the first step to correcting defective rims and replacing tires on a bicycle. Changing tires or temporarily removing them with your own hands is just as easy, just give a little space and time.

Experience shows that rear tires wear out 3 times faster and more often than front ones. This happens because the rear wheels are the driving wheels of the bike. In addition, they have a much greater burden. This distortion is especially observed in bicycles equipped with rear brakes.

Important! Some cyclists swap front and rear tires in the mistaken belief that this way they can "align" them. In fact, wear is a natural and inevitable process. You can try to move it a little in time, but it is not possible to prevent it completely with intensive driving. Tire damage can be repaired in only 2 ways: by sealing the inner tube or by replacing it (if the bike tire is unrepairable).

Damage

The tire is most vulnerable to external mechanical impact if the wheel is not sufficiently inflated. Cracks in the tread are not dangerous. Let's list types of tire damage:

Bicycle tire cut on the side or in the middle due to collision with glass fragments, pointed stones or pieces of rebar.
Tire puncture with a nail, tiny piece of glass or wire, most likely in worn tires or lightweight sports tires.
"Snakebite", so named because of the double hole that is formed due to the pinching of the wheel chamber when it hits an obstacle between the tire and the rim.

Wear

Externally, wear manifests itself in the form of hardening of the tire, loss of elasticity and subsequent cracking. Tire wears out prematurely due to a range of reasons, including the following:

adverse weather conditions;
incorrect operation;
low-quality bike rim with sharp edges;
unfavorable condition of roads;
poorly tuned bike brakes;
high humidity.

Important! It is not always possible to avoid the influence of these factors. If wear or damage to the tire is already taking place, it is necessary to solve the situation by replacing or repairing it. To do this, the tires must be removed from the wheel. If you use the mounting blades, the process is greatly simplified.

Benefits of using mounting blades

To remove a tire from a bicycle wheel without any tools at hand, you need to be an experienced bike mechanic. If you are not one, then it makes sense to use montages. This special plastic blades sold as a set of several pieces. Their main advantage is the material from which they are made. The fact is that the use of metal improvised means (keys or screwdrivers) will most likely lead to damage to the rim or cord of the camera. Mounting blades avoid such negative consequences. How to use it to disassemble, we will now find out.

Do-it-yourself step-by-step instructions for disassembling

For work, you will need assembly tools, which can be purchased at any specialized store. Consider a step-by-step sequence for removing a tire.

Remove the wheel by unscrewing the nuts that secure it to the bicycle frame. IN modern bicycles this can be done without much difficulty, since they are equipped with a quick-release mechanism. In other cases, WD-40 will help.
Unhook the brake pads. When working with the rear wheels, you need to switch to a lower gear and remove the chain from the sprocket.
Press the valve on the nipple, lowering the wheel to the end. In the case of a tubed tire, it is necessary to completely unscrew the nipple, pull the tubed "nipple" outward, and then remove the tire.
Insert 2 mounting spatulas under the tire at intervals of 10-15 cm.
Take 1 spatula and gently move it in a circle in the direction opposite to the other shoulder blade.
Remove tire.

Important! After removing the tire, you need to make its external inspection, chambers and wheels for defects and damage, check if there are protruding spokes or other sharp objects on the rim that must be removed.

Camera repair after disassembly

Tire removed. Now the wheel needs to be checked. When damage is found, a decision is made as to whether the tubes and tires should be replaced or repaired. In the first case for restoration of wheel integrity You will need a bicycle tool kit. Sticking the bicycle chamber is as follows:

pump some air into the chamber and immerse it in water: air bubbles will be visible in the place of the hole;
wipe the chamber dry, clean the breakdown site with sandpaper;
smear glue on the breakdown site, glue the patch, place it under the press;
after the glue has dried, perform a control inflation of the tire, check if it allows air to pass through.

Now that we have made sure that the tube and tire are in order, we can begin the reverse process - beading.

Bicycle wheel beading at home

If you are an avid cyclist and assume that in the future you will remove / replace tires on the wheels of your bike more than once, then it makes sense to purchase or make your own beading machine. He greatly simplifies the matter. However, if it is not at hand, and you need to assemble the wheel urgently, you can do without it. The sorting is performed in the following sequence.

Place the tire on one side of the rim in the indicated direction of travel.
Inflate the chamber not to the end, insert it into the rim.
Fill the “nipple” into a special hole on the rim.
Insert the tire into the rim with a mounting spatula, starting from the “nipple”.
Check the correct position of the chamber: it should not be pinched anywhere, so as not to burst during inflation.
Pump up the chamber a little more, fix the wheel on the bike.
Fill the wheel with air to the end, put the chain in place, fixing the brake pads.

We examined the main nuances and "pitfalls" of the stripping/boarding process bicycle wheel, and also analyzed the causes of wheel wear and learned how to seal the bicycle inner tube. Finally, I would like to give one more important advice. To make your bike trip truly cloudless and not overshadowed by anything, take a repair kit and mounting blades with you on the road just in case. Good luck!
