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.
Always have with you
The easiest option is to carry your camera and pump with you. Not every damage can be sealed, and the easiest way is to change the entire camera. The only drawback of this kit is weight and volume. A set for gluing is a small box, but a spare tire is already a serious piece of rubber that can interfere in a small bag, if you have it with you at all.
Unfortunately, the condition of the roads and the general sensitivity of modern bikes to damage means that it is impossible to travel beyond the city center without a spare bicycle camera or a repair kit. What is needed for replacement in the minimum version?
- “Spare wheel” or repair kit.
- Key or multitool if the rear wheel is not mounted on an eccentric.
- Pump to pump a supplied or repaired chamber.
With these tools, you can easily unmount the rear wheel, remove the camera and install a new one in its place.
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.
- 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 wrap 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 patch to form a single whole with the camera.
- Degreaser. rare, but appears in kits. One of the main problems during gluing is the residual grease or grease on the surface, which does not allow the patch to stick; the camera can be treated with a degreaser before 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.
So, what actions need to be performed to change the camera. Everything is simple, the main thing is accuracy and a small amount of physical strength.
- Flip the bike.
- If the brakes are V-Brake. remove (open) them.
- Loosen the screw or release the wheel with an eccentric.
- Raise the chain, remove the wheel.
- Release air from the chamber (if any).
- Pry the camera with a bead or any other elongated object (keys, screwdriver, multitool) at two points, at a distance of 10-20 cm from each other.
- Expand the dots little by little, freeing one side of the camera.
- Pull the nipple out of the rim.
- Get the camera.
So, the camera is removed, you can repair it or print a new one. Installing everything back:
- Route the tube inside the rim.
- Check the nipple and space under the tire for nibbling and wrinkling.
- Pump up the camera a little so that it takes shape.
- Insert the tire back behind the rim.
- Put the wheel in place (you should be careful with the chain, it is easy to confuse its position).
- Secure the wheel with a screw or eccentric.
- Reinstall the brakes.
- Pump up the camera.
- Flip the bike.
That’s it, the replacement is complete! As you can see, there is nothing complicated in this process.
Those who changed the camera with their own hands know, perhaps, the main problem. this is the bending of the tire bead. Modern tires fit so well to the rim and are so stiff that it is not always possible to do it with your hands.
Therefore, stripping is added to the composition of many multitool or kits. These are small plastic or metal “spoons” that are inserted between the tire and the rim, allowing you to pry and bend the tire, and then put it back on.
How to properly change the camera on a bike?
The reasons for replacing a wheel can be very different. from frequent breakdown by a nail or “snake bite” by the edge of the rim to updating the wheel and transferring an old proven camera to it. There is no difficulty in changing the camera on a bicycle. Let’s consider how to do this, and what you may need in the process.

Not everyone punches their own wheels, and not everyone repairs a bicycle on their own. Nevertheless, understanding how you can remove a tire from a bike and put in what you need for this and how to do it easily and without unnecessary problems is useful for most riders.
When we remove a bicycle tire?
- The camera is broken. you need to remove the tire, then change the camera, and then assemble the wheel;
- When replacing, in fact, bicycle tires. they tend to wear out, especially with aggressive or prolonged driving;
- When servicing the wheel. when other elements, for example, the camera, can interfere.
After the glue is dry, take the patch and press it firmly against the surface of the camera. You, of course, can feel like a vice, standing in this position for several minutes, or you can take a dumbbell, for example, and put the patches on top of the floor for an hour. When the whole thing is settled, you can remove the protective film on top of the patch and safely put the camera back into the wheel.

A puncture on the road is the most common and common problem among cyclists. Absolutely every cyclist can face this failure, therefore, it is very important to know how to act correctly if a wheel puncture has already taken place.
How to Properly Seat a Stubborn Bicycle Tire
Most often, bicycle tires have a tread, which can be used to judge the level of tire wear. If the tread has worn off and the center of the tire has become smooth, then the rubber has outlived its time and should be replaced. If you continue to ride on a worn tire, the chance of getting a puncture increases significantly. In slicks. initially smooth tires, in many models, special notches are made deep into the tire. When the notches are no longer visible, this is also a sign that it is time to change the tire.
So, what needs to be done to remove the tire from the bike?
- We begin to remove the wheel by washing out the brakes (in the case of V-Brake) or removing the caliper (disc), they can greatly interfere with the next steps.
- Loosen the bolt or eccentric holding the wheel in the frame.
- We take out the wheel.
- We release excess air from the chamber through the nipple, it is important that there is as little air as possible, otherwise the chamber can easily be touched and damaged.
- We pry off the edge using a flanging or replacing it at one point.
- We measure 10-15 cm and repeat the operation, bending the segment between the two bevels, and, taking it outside the rim, outward.
- Carefully continue removing the tires until one side is completely behind the rim.
- We repeat the action in the same direction with the second side of the tire. Usually this stage is already easier.
Repair of the camera only is limited to items 1-7.
- It is necessary to put on the tire, starting to lay it inside the rim with one side.
- On the last 15-30 cm, we fix one side of the tire with a bead and carefully transfer the entire edge inside the rim.
- Place the edge of the tire inside the rim and install the camera.
- We repeat the process of folding through the rim with the second edge of the tire to finally put it on.
- We mount the wheel, close the brakes.
Tips & Tricks to Install a Really Tight Difficult Bike Tire
Do not forget that all actions should be carried out correctly. Rubber does not like heavy loads, especially the thin and soft rubber used in cameras. All operations with the tube inside the tire should be done delicately.
Installing unidirectional tires
The rubber of a modern bicycle wheel in most cases consists of a tube and a tire (tire). We do not consider the one-tube option. Let’s talk about installing a tire. precisely about its correct orientation.
If the tread pattern is symmetrical, then it can be installed either side. But there are also unidirectional tires, i.e. with an asymmetrical tread pattern designed to fit and rotate in one direction. For these tires, the orientation during installation is already important.
Some manufacturers clearly and unambiguously draw an arrow in accordance with which the wheel should rotate with the recommended installation.
If installed on the front wheel. see the arrow Front, in the back. Rear. Sometimes a tire is specially designed to work only on the rear wheel or only on the front wheel. Then the manufacturer also makes a warning label:
Installing such a tire in the wrong orientation results in poorer traction, worse bike handling, less rolling and faster tire wear.
If an arrow is drawn and it is signed in letters on the rubber how to install, then everything is simple. But what to do when the tire is clearly unidirectional according to the tread pattern, and there are no arrows or other indications?
Recommended installation is such that the rear wheel leaves a mark. and the front when moving from left to right.
The reason for this recommendation. The rear wheel is responsible for traction and flotation, so the V must rest with its feet on the ground for better traction (/ \). The front wheel plays a greater role when braking, so the pattern is oriented in the opposite direction.
If you need maximum flotation, use both tires. Option two does not seem to make sense practically useful.
The issue of grip / braking in relation to the orientation of the tread pattern is important when driving on soil, sand. On the asphalt it doesn’t matter.
And one moment. If you look at a Belarus tractor or car tires, you will notice that the tires are installed there exactly the opposite: It would seem that a tractor in the field needs maximum cross-country ability, and auto grip will not hurt. But here another factor plays a role. aquaplaning. At high speed, with a sufficient wheel width, water from the road surface can collect in a wave in front of the wheel and the vehicle slides on a water cushion. The oriented pattern allows water to be squeezed out along the sides of the wheel and maintains grip. In principle, aquaplaning does not threaten a bicycle due to the shape and size of the contact patch of the wheel with the road, high tire pressure and relatively low speed.
Preparatory step before removing tires
Immediately, as soon as you notice that the wheel is “flat”, get off the bike. Further long-term movement on an iron horse in this form will damage its moving parts even more. It is better to repair a wheel in a special room. It does not rain on you there, if it has gone, and there is all the necessary tool.
What a cyclist should always have in stock:
Ideally, there should always be a repair kit, a spare chamber, a pump. Together, this makes up an impressive weight and takes up a lot of space. For a small bike, this is inconvenient, but it is not always possible to limit yourself to ordinary gluing. What you definitely can’t do without:
All of the above will help to dismantle the damaged wheel and install a new one, with the installation of the camera.
The first stage of repair work is completed, we are starting to install the wheel
- Make sure the rim, tire and tube are free of sharp, foreign particles and protruding parts (such as spokes).
- Pump up a little camera.
- Check the spool, insert it into the rim hole.
- Place the camera carefully in the tire cavity.
- Using a special tool, or another suitable tool that does not have sharp edges, tuck the edges of the tire into the rim. If you can do it only with your hands, then the tool is optional.
- Pump up the wheel, knead the tire. The camera should unfold freely, creases are not allowed.
- Place the wheel on the bike and secure with the screw.
- Inflate the chamber fully and screw the caps on the nipple.
The wheel repair process is over and you can move on.
Understanding the question of how to replace the bicycle wheel camera
There are more and more people who like to ride with the breeze on a two-wheeled iron friend. The number of those who are faced with the everyday problem of punctured wheels is also increasing. Changing them is not the most difficult thing, but skills are needed here and there are some rules. This article will help you figure it out.
