Replacing A Tire On A Bicycle Rear Wheel

Replacing the camera on a bicycle rear wheel

Puncture of a wheel on a bicycle is a very frequent, one might even say, everyday occurrence. Especially if driving on rough terrain is often carried out, or if not very high-quality, worn tires are used. Therefore, every cyclist should learn how to change the camera on his own. Moreover, knowing the instructions and important nuances, it is very easy to do this. And it is not at all necessary to contact the service center for help.

The size

When choosing a bike tube, make sure that it exactly matches the size of the wheel. But the sizes of the wheels of iron horses are different:

  • For mountain and city bikes. 26 “, 27.5”;
  • BMX and children’s models. 20 “;
  • Niners Road Bikes. 29 “.

To properly change the tubes, pay attention to the markings on the tires. The first two digits respectively mean the size of the landing diameter and width of the tire in inches. Further, in brackets, the same parameters are indicated, but in millimeters.

What pressure should be in the bicycle chamber

The value of this parameter depends on the type of tire. To minimize the risk of damaging your bike tube, consider the dimensions of your bike tire. Typically, the minimum and maximum allowable pressure values ​​in the chamber are applied to the tires. For hardtails, this parameter is 2.5-3.0 atmospheres. For two-suspension bikes, it can be increased to 5.0.

If the wheel is large and poorly inflated, the likelihood of breaking the integrity of the rubber is higher. In addition, the roll is getting worse, it is more difficult to ride. If the wheels are too inflated, then when driving on bad roads, shaking intensifies, and permeability becomes worse. It is also necessary to take into account when optimizing pressure and own body weight. The higher it is, the more pressure inside the wheels should be.

Manufacturing materials

Cycling cameras can be made from the following materials:

  • Latex. These products are made on the basis of highly elastic natural rubber. The main advantages are minimal energy losses and low weight. Latex is used to make cameras for racing bicycles;
  • Butyl rubber. It is a synthetic budget material that is used in the manufacture of bicycle cameras designed for everyday riding. Inexpensive material, good air holding, wear resistant.

Conclusion

Changing your camera is a simple process that every cyclist should be prepared for. A puncture on the road, damage to a camera in the forest, or just updating a bicycle wheel. it’s always nice to deal with the problem yourself and quickly deal with the problem, and not carry the bike to the workshop.

Every serious cyclist already carries a repair kit and a pump with him, being ready for any surprises.

Useful tips for replacing the camera

These little tricks can help you swap cameras faster and with less effort.

  • Before mounting a new camera, pump it up a little;
  • Make sure that there is no oil on the bicycle tubes, tires and brake pads;
  • When using a spoon or special spatula, proceed as carefully as possible so as not to damage the camera;
  • Inflate the bicycle tube with the pressure indicated on the tires. If overdone, she may NOT take it;
  • When buying a new bicycle rubber, choose it for the hole on the rim, as the valves are different;
  • If you notice that the bike tube is damaged, DO NOT continue driving until you change it. First, it will tear even more when moving. Secondly, you risk damaging Not only the tires, but also the rim.

How to choose the right bike camera

Now a few words about how to choose the right bike cameras for replacement. The main parameters of the VELOBIKE camera are:

  • A kind of nipple;
  • Chamber material;
  • Rim: the size of the landing diameter;
  • Bicycle tire width.

Types of velonipples

This part is designed to pump air into the chamber. Depending on the version, there are such types of nipples for bikes:

  • Rubberized. They are inferior to metal ones in terms of reliability and convenience. Compared to a metal product, there is a greater likelihood of damage to the rim hole or tearing if not properly used;
  • Metallic. They are equipped with a special locking nut that prevents the nipple from dislodging during inflation.

Assigning a camera to a bicycle

Bicycle tubes are designed to hold air in the wheel, give shape, elasticity and stability of the tire. This is a tube made of elastic material, equipped with an air injection nipple.

If you are going on a long bike ride, it is advisable to take with you, if not a wheel, then a spare “rubber” and a pump. If there is no spare wheel, grab at least a rubber repair kit.

Repair kit

The repair kit should be considered separately. Many do not open it from the moment of purchase, but in fact, you can assemble it yourself. Homemade repair kit comes out several times cheaper.

Replacing A Tire On A Bicycle Rear Wheel

What’s in the repair kit?

  • Patches. usually several pieces of 2-3 different types. In modern industrial kits, patches are made of synthetic rubber, smooth on one side and rough on the other. On the smooth side, they are sealed with foil or plastic foil to stay clean.
  • Camera cleaning tool. for better adhesion, the surface should be clean and slightly rough, for this use a small metal “grater”.
  • Glue. glue for rubber, “melting” it and forcing the image board with the camera into a single whole.
  • Degreaser. rare, but appears in kits. One of the main problems during gluing is residual grease or grease on the surface, which prevent the patch from sticking, the camera can be treated with a degreaser to the gluing.

Recently, some have been using anti-puncture gels, and it is enough to pour sealant into the new chamber before pumping and carefully “disperse” it along the inner cavity of the chamber.

How to glue the camera

1. Find the puncture site. At home, this is easy to do: you need to fill the sink with water and immerse the pumped up chamber there. bubbles will immediately run out of the hole. In the field, everything is more complicated. I usually pump the camera harder and listen with my ear where the air comes out. Localizing the hole with water droplets from a flask.

2. Wipe the puncture site dry, and then clean it with sandpaper and a brush, which are in the repair kit.

3. Apply an even and thin layer of glue to the patch (or even to the camera). Wait five minutes for the glue to dry.

4. Gently apply the patch and squeeze with your fingers for a couple of minutes. Then, after waiting another five minutes, put the camera in the tires and pump it up. No need to put maximum pressure, the patch should come up completely.

PS. A small subtlety. almost all tires have an arrow indicating the direction of travel. This rule must be observed, because the efficiency of the tread pattern depends on it.

If everything is done correctly, the reliability of such a sealed chamber is absolute. I had cameras with 5-8 patches and nothing. no problem.

In addition to puncture and snakebite, cameras tend to deteriorate with age. This can manifest itself in cracks, as a result of which one day it will explode. The nipple may come off, just this happened to me twice in one day (!) On a bicycle trip in France.

Therefore, once every three to four years, it makes sense to replace cameras with new ones, even if outwardly they look NOT damaged.

Consider also the fact that there are rims in which only Presta nipples (bicycle) fit, and if you buy a camera with a Schrader nipple (car), it will be an unpleasant surprise on the road.

The whole time I was unable to find MTB tires that I could mark as puncture resistant. I blame my big weight for this, because all my light cocatals had an order of magnitude less ribs than me.

If someone is looking for a narrow tire at 26 “for pure road use, I recommend Continental Ultra Gator Skin, my wife drove half of Europe on it without a single puncture.

With road and hybrid tires, I was more fortunate. Very good rubber is produced by the Continetal company. I can only praise their Continental Grand Prix road racing tires and the Continental 4 Season training tires (can be used on hybrid). Remarkable workmanship and resource.

Replacing the camera on the rear wheel bike. Installing new tires

1. We put on new tires on one “edge” of the wheel, so that we have a free for inserting the camera.

2. We take a new chamber (deflated) and, starting with the nipple, lay it along the rim.

3. While the camera is NOT closed yet, pump it up a little to make sure it is laid flat and not distorted anywhere. If the camera is kinked or twisted during the installation process, it will most likely burst as soon as you get on the bike. Agree, you don’t need such unnecessary frustrations, because these are NOT only Spoiled plans, but also additional financial costs.

4. Now you need to “tuck” the tires into the rim. In the first steps, this is done manually, but at the end, editing will be required again. You can do it with one, but it’s better to use two. Use it to pull the tires slightly towards you so that it fits easily into the rim. You can push the tires a little inward with the assembly so that it is better fixed. The main thing is that the mounting depth is the same throughout the entire circle.

5. After the wheel is closed, pump the chamber to the desired state. Usually, the correct pressure is indicated on the tires, check it to properly adjust your pump.

6. Now screw the cap onto the nipple to fix the condition of the wheel.

7. It remains to install the wheel in place and that’s it. Now your bike is back on the move! Do a small circle on it at low speed to make sure everything is secured correctly and you feel comfortable. If necessary, pump up the chamber of the second wheel so that they are equally elastic. Many cyclists experience minor riding discomfort after replacing one camera. If everything is ok, you can go on the road. Suddenly what happens, you already know how to change the tire and you can do it even in field conditions.

Training

If we change the camera in “ideal” conditions, we already have a garage ready, a toolbox, a repair kit, and a new camera. Unfortunately, things are not always so “successful”. It may turn out that the camera burst on the street during a long drive or even at a competition.

How to install a camera in a bicycle wheel

  • First you need to check if there are any sharp objects left in the tires, which can damage the new or sealed camera. To do this, you need to visually inspect the tires, and also run your hand along its inner side. It is also worth noting whether any spoke or spoke is protruding into the wheel. If in any doubt, stop installing the camera.
  • Inflate the camera slightly to avoid damage during installation.
  • Now carefully insert the nipple into the corresponding hole in the rim, then put the entire tube inside the tire.
  • Tuck the edge of the tire over the entire diameter of the wheel into the rim. Most likely you will be able to do it with your hands. However, it is possible that a part of the edge remains that is difficult to thread into the rim. Then you should again use the assembly and fill the tires with it. At this stage, there is a danger of piercing the camera with a rig. be careful.

The sequence of how to change the camera on the bike yourself

The replacement takes place in the following sequence:

  • Unscrew the nuts with which the wheel is attached to the frame. If you cannot do this, apply a special lubricant, for example, WD-40. Modern modifications of cycle bikes have a quick-release mechanism that allows you to cope with dismantling a wheel in just a few minutes;
  • Remove the bike wheel. In order to freely pull out the front wheel is large, disconnect the brake pads. To remove the reverse. Remove the chain from the sprocket after shifting to the lower gear;
  • Release the air from the chamber by pressing the valve on the nipple. If the air does not come out well enough, squeeze the bike tubes with your hands
  • Pull out the bike tubes from under the tire. To do this, pry it off with a non-sharp object. You can purchase a special “spatula”, or you can use an ordinary metal spoon for this.,
  • Unscrew the nipple. In the event that the bicycle tire is tubular, then you have to Unscrew the nipple entirely;
  • Pull out the “nipple” and carefully remove the tires;
  • Let’s make a thorough inspection of the rim. If there are stones or other sharp objects, remove them. Using electrical tape, check if the spokes of the bike are sticking out. These precautions are necessary to avoid getting punctured again;
  • Change your bike cameras. First, download a small amount of air inside the new “rubber”. Then mount it under the tires. Do not forget to check that She is not pinched and is installed correctly. Pay attention to the corresponding markings on the bicycle tires to fit them correctly, taking into account the direction of the tread pattern. Put one side on the rim first and then the other. Then pump up your bike tubes and insert them into the rim. Insert the “nipple” of the bike tube into the hole on the body. If the work is not progressing well enough, then use a special spatula or spoon;
  • Re-fasten all wheel parts. If it is the front wheel of the bike, attach the brake pads. Secure the fixing nuts. At the same time, make sure that the distance between the wheel and the fork is approximately the same. Now you can fully inflate the VELOBIKE wheel chamber. If the rear wheel fails, remember to install the chain.
