Change the camera on a bike with your own hands

Using a repair kit

Novice bike enthusiasts often ask themselves the question: how to seal the bicycle camera using a repair kit. Detailed instructions are written on the packaging, but the sequence of the process can be confused.

change, camera, bike, hands

Carefully study the instructions that come with such a kit.

The kit includes: 5-6 rubber pads for all types of damage, special quick-drying glue, a piece of sandpaper for cleaning the joints, a bottle of acetone for degreasing the surface and plastic assemblies. There are kits sold with self-adhesive adhesive patches. It is enough to remove the protective film from the cover and apply it to the cleaned surface of the camera. It is quite problematic to remove such a patch from rubber, therefore, when applying it, you need to be careful and precise. The patch will serve until the camera is replaced, they can be applied countless times.

The adhesive composition is enough for the number of patches that are attached.

Special glue

To glue the tires on their own, several compounds are sold, moisture resistant and designed for difficult working conditions. for heavy loads.

This is not really an adhesive, but a cold vulcanization agent, which is much more effective.

Types of glue for repairing a bicycle camera:

  • Moment. Suitable for universal, “crystal”, “extra” and rubber. These compounds are used for all rubber compounds. Complete drying of the patch takes 24 hours. For quick repairs, pay attention to the “superglue” from this series. It is sold in small tubes that you can always have with you and use when needed.
  • Tip Top SC. Consists of two components. It is used at a temperature of 10-25 degrees. Demanding for cleaning and degreasing glued surfaces. To obtain glue, mix 10 grams of base and a drop of hardener, smear the joints and press them together. The camera will be ready for travel in 10 minutes.

Quite a rare two-component adhesive, but one of the most tenacious.

If it is impossible to properly repair the wheel in the field. PVC tape or stationery tape will help you get home. The method is very unreliable, but it will help to drive several kilometers.

As a temporary measure. quite yourself, in other cases it is better to take a specialized glue for rubber.

It is necessary to disassemble the wheel and find the puncture site. In case of minor damage, carefully wrap the camera over the puncture for 2-3 layers. Insert the tube into the tire with extreme care, without breaking the “wrapper”.

This method can help you get to the house, where you can already seal the camera properly.

How to glue with your own hands

Beginner cycling enthusiasts know little about how to remove a wheel, disassemble it and which side to glue the patch to the bicycle camera. Have to learn how to deal with it on your own.

To begin with, we just try to find the place of damage by carefully examining the surface of the camera.

How to remove it correctly

When disassembling, you need to remove the cap, unscrew the spool and deflate the bicycle wheel, so it is easier to reach the camera. With a plastic mounting we hook the rim in several places, 2-3 points are enough to pull out the bike camera. Instead of a mounting, you can insert a screwdriver or an ordinary spoon to bend the tire away from the rim. Gently pull the camera out of the tire, and you can start looking for the place of damage.

For an experienced cyclist, this procedure takes about 15 minutes, a beginner will need about half an hour.

Sealing the camera on the bike

Lovers of fresh air switch to a bicycle for a pleasant pastime or to get to work, which is economical and useful. A road accident can happen any time the wheel is deflated. A beginner may be faced with the question: how to glue the bicycle camera at home so as not to contact the service.

If you have a bike, then sooner or later you will face such a situation as a puncture of the camera.

Finding damage

  • You can find the puncture site by ear. To do this, you need to pump up the camera a little and listen to where the air comes out. Place a mark with electrical tape or chalk where you need a patch.
  • It is easier to locate the hole with a bowl of water. We lower the pumped-up camera into the water and fix the place where the air exits, you can insert a match into the hole. But before gluing the puncture site, the camera must be dried.
  • The hole can be found with a soapy solution, this will dry the chamber faster and keep the patch clean. Add 3-4 drops of dish detergent to a glass of water, whip up the foam and apply it with a sponge on the surface of the camera. The puncture site will bubble.

Before starting repair work, pay attention to the condition of the rubber. Severe abrasions and many small cracks signal that it is time to change the camera, and not glue it.

Carefully remove the nipple from the rim and take out the camera.

Preparing the camera

To find the puncture site and make repairs, you need to remove the wheel from the bike.

It will be necessary to disassemble the bicycle wheel, seal the hole and put everything back.

On mountain and sports bikes, the wheel is latched and removed in half a minute. Simple road bikes will require a wrench.

The better to glue the camera

When riding a bike, you should always have the necessary wheel removal wrench set and a repair kit with you. It will help at home and in the field when repairing a puncture. Driving on a flat tire can compromise the integrity of the tire and deform the rim. This will result in a wheel change, which is an expensive purchase.

First of all, you need glue, which, after drying, retains elasticity, that is, does not harden.

The required set is very limited, which allows repairs to be carried out in almost any conditions.

Installing a new tire

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

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

While the camera is not yet closed, pump it up a little to make sure that it is laid flat and not twisted 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.

Now you need to “tuck” the tire 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 tire slightly towards you so that it fits easily into the rim. You can push the tire 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.

After the wheel is closed, pump up the chamber to the desired state. Usually, the pressure you need is indicated on the tire, check it to get your pump set up correctly.

Now screw the cap on the nipple to fix the condition of the wheel.

It remains to put 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, inflate 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.

We take out the punched camera

To remove the damaged camera from the wheel, it is necessary to remove it from the bike. it is much more convenient to work this way. Then follow the step-by-step instructions:

1.Unscrew the protective cap from the nipple. If necessary, completely deflate the wheel. This will make the job easier, since there will be no unnecessary resistance.

2.Using the razor, hook the edge of the tire and pull it out of the rim. Special tools allow this procedure to be carried out quickly and as painlessly as possible. If you don’t have a rigger, you can try using any thin and sturdy object, such as a spoon. Its handle has repeatedly helped out cyclists who did not have repair tools at hand. Make sure that it does not bend over.

Important: The tool should not have sharp ends, so a screwdriver is not the best solution, although it does fit the intended shape. You can only damage the wheel more with it. If you want to keep the tire, don’t.

Optimally use two assemblies. First, pick up the edge of one, then, when you fix the position, in 2-3 centimeters, pick up the tire with the second mounting. This will be followed by a release of pressure, and the work will go easier. Continuing to support the first assembly with your hand, continue to pry the tire in a circle with the second until it is completely released from the rim.

4.Now that one edge of the tire is completely removed, release the nipple and remove the damaged tube.

We will consider the installation process with the installation of both a new camera and a tire. If you keep the old camera, skip the first step.

Sequencing

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 camera can easily be touched and damaged.
  • We pry off the edge with the help of unbundling or its replacement 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.
  • Done!

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.
  • Done!
  • We mount the wheel, close the brakes.

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.

How to change a tire on a bicycle

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 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.

Tools

Different tools will be needed depending on the design of the bike.

THE MOST UNIQUE CAMERA ANGLE. How to build BODY CAMERA (a.k.a. SNORRIECAM)

The minimum set is hands (preferably with gloves), nothing else is needed. What is used to facilitate the process?

  • Dismantling a bicycle wheel. small oblong plastic plates with a “hook” at the end. Very helpful to hold the edge when starting to dismantle without effort, and then remove it.
  • Any replacement of the folding. keys (from locks or wrenches), coins, sticks are often used (which is quite traumatic, by the way).
  • Wrenches for removing the wheel. there are also models where the axle is fixed with bolts, not eccentrics.
  • Pump. needed when installing the wheel back.

Do-it-yourself tire removal is no big deal, and most riders do this repair exercise the first time around. Accuracy of execution, the availability of convenient tools. and changing the camera will not be difficult.

If you are a cyclist, you need to be able to deal with a number of common problems that can happen on the road. A broken wheel is one of the main ones. Unfortunately, you can hit a nail, a piece of metal or a broken bottle almost anywhere, and sooner or later it happens to everyone. Happened already? Read our review, which we prepared together with Onliner, on how to change or glue the camera, tire in a bicycle.

Important points

Try not to rush during the procedure and be attentive at every step. Any carelessness can then turn into problems on the road. If you keep an old tire, do not forget to check the inside of the tire for any piercing or cutting elements. It often happens that part of the object that pierced the camera breaks off and remains in the tire. This could damage the camera again. So, if you managed to find the “culprit” of the tragedy, make sure you remove it completely.

When working with a montage, be sure to hold it with your hand, even if it seems to you that it is holding itself. The resistance of the tire can easily push it out. At best, it will just fall and you have to start over. At worst, it will fly out with force and can hit you in the face. Feeling unpleasant, not to mention the fact that it can be traumatic.

If you decide to change the camera for the first time on a bike, or it happens that after the change, the camera releases, it will be useful for you to read these tips.

Before unscrewing and removing the wheel, if it is not fully deflated, completely lower it by pressing the nipple. This will make it easier to remove it from the brakes.

We unscrew the wheel with two keys at the same time, if there is only one available, then we turn the nuts in turn one by one on each side.

We take a special plastic plate and insert it between the rim and the tire. We pull on the tire and hook the plate by the spoke.

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

First of all, insert the nipple and secure it well with a washer. Next, we push the camera under the tire with our hands 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 moment 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 spins 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 slightly release the fixing nuts on the sleeve.

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.

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.

Disassembly

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.

Repair kit

The repair kit should be considered separately. Many do not open it from the moment of purchase, but in fact it can be assembled on your own. 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 prevents the patch from sticking; 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.

Always have with you

The easiest option is to carry your camera and pump with you. Not every damage can be sealed, and it is easiest to change the entire camera. The only drawback of this kit is weight and volume. The set for gluing is a small box, but the “spare” 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 bike 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.

Using these tools, you can easily unmount the rear wheel, remove the camera and install a new one in its place.

How to properly change the camera on a bike?

Reasons for replacing a wheel can be very different. from frequent nail breakdown 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.

Replacement procedure

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.

Changing your camera is a simple process that every cyclist should be prepared for. A puncture on the road, damage to the 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 eventuality.

Required tools

If during walks you often travel far from home, then it is worth having with you the minimum set of tools that you will need to replace the camera in the field.

Bicycle Camera Replacement Tools

  • Bicycle mountings. plastic or metal mountings greatly simplify the bead of a wheel tire. 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 will not be able to leave on a flat tire. ))
  • Spare camera
  • Bicycle first aid kit. a set of patches and glue for repairing a punctured camera.

Repair kit. bicycle first aid kit for a bicycle camera

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

How to change the camera on a bike

For most beginners, the question of how to change the camera in a bicycle wheel arises only after the first puncture and causes concern. In fact, this is one of the easiest processes to maintain a bicycle if you have the necessary tools and a little 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. Punctures often occur when riding on rough terrain, especially if the bike is equipped with low-quality rubber.

How to remove the camera from the wheel

If a puncture still occurs, then to replace the camera, you must first remove the wheel from the bike, and then disassemble the tire to pull out the cameras. This process is quite simple if you have bicycle rigs with you.

First, it is necessary to deflate the chamber to the end, if this did not happen during the puncture. Then we insert one of the assemblies between the tire and the rim, then we pry the edge of the tire with it so that it crawls out of the rim.

Insert the mounting (smooth end of the key) between the tire and the rim

Pry off the edge of the tire so that the edge crawls out onto the road

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

Then, in the same way, we insert the second editing.

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

Removing the camera from under the bike tire

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 repeated puncture. This should be done carefully as 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.

We insert first the nipple, and then the whole chamber

The worn tube 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 flip the tire onto the rim and you can often do without edgers and do it with your bare hands.

Use edgers if necessary

With the tube on and the tire in place, you can inflate the wheel, adjusting the tire in the process so that the edges are evenly positioned on the rim. We put the wheel in place and you can hit the road!)

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

How to seal a punched camera

There is not always a need to replace a broken camera on a bicycle; sometimes it will be faster and more economical to simply patch it up. For this you need:

  • Find the punctured spot. By removing the tire and taking out the punctured tube, the damage can be easily detected. The simplest option is to pump the latter with air and determine the defect by hissing (or by bubbles, if you put it in water).
  • Mark the location of the damage. Sometimes several punctures can form, and they will be so small that it will be difficult to notice them right away. Therefore, each place must be marked with some kind of sign, for example, a chalk cross or a marker. For holes, you need to make large marks so that the defect remains visible even after a generous application of glue.
  • Sand the surrounding area if necessary. It depends on which patch is being used. You can see the recommendations in the instructions for the repair kit. If nothing is written there, it is worth lightly sanding the surface with sandpaper. A little preparation will definitely not hurt the repair.
  • Stick on the patch. The manufacturer’s instructions must also be followed here. Self-adhesive patches are much more convenient to use, but they are less reliable. Variants that require glue are safer, but require a special rubber compound.

A little skill and practice, and every time you don’t have to think about how to change a damaged camera on a bicycle correctly. If it is badly worn out or damaged, it is better not to suffer with gluing patches and replace it with a serviceable one. For large punctures, even after proper repair, the decals will release air from the chamber, which will interfere with cycling.

Any cyclist can change a tire. Be prepared for necessary repairs, carry tools and materials. Having fixed the bike with your own hands once, you can also help your friends with advice and deeds.

What is needed

If a cyclist plans to go out of town or far from home during a walk, it is advisable for him to take with him a minimum set of devices with which he can carry out repairs with his own hands. On the road you may need:

Do-it-yourself tire removal is no big deal, and most riders do this repair exercise the first time around. Accuracy of execution, the availability of convenient tools. and changing the camera will not be difficult.

Replacement procedure

  • Remove the nuts that secure the wheel to the frame. If difficulties arise with this, you can use a special lubricant. Most modern bicycles have a quick release mechanism.
  • Get the wheel out. To remove the front element, as a rule, it is necessary to disconnect the system with the disc brake pads, and for the rear wheel, you will need to remove the chain from the sprocket.
  • Blow off the camera. After releasing the air, make sure that the wheel is completely deflated. This is done by pressing the special valve in the nipple. Sometimes it may be necessary to squeeze the chamber by hand if the air is coming out slowly.
  • Remove the tire. As mentioned earlier, bike assemblies are best suited for this task. If they are not at hand, you can do it with a mild object or a regular spoon.
  • Unscrew the nipple (when provided). If a bicycle uses a tube tire, it is usually necessary to completely unscrew it to remove it.
  • Inspect the rim. Before starting the procedure, it is necessary to conduct a short diagnosis of the element for protruding spokes. You can also use duct tape. So that new damage does not form soon, you should carefully examine and remove all pebbles, sand and sharp objects, if any.
  • Replace camera. First you need to fill it a little with air, and then mount it under the tire. This is done carefully. You should also make sure that the camera is inserted correctly and that there are no pinches anywhere. Most tires have mounting guidelines to prevent a person from installing the camera on the bike in the wrong way. Its sides are worn alternately. First of all, the “nipple” is tucked into a special hole on the rim, after which the entire tire is inserted. If the camera enters with difficulty, you can help with a spatula.
  • Secure the structure. After installing the camera under the tire, you need to fix everything in its place. The first step is to secure the brake and then install the retaining nut. Next, pump the chamber with air to the end. If the work was carried out with the rear wheel, you need to return the chain to its place.

When installing parts in their places, make sure that there is no oil and grease on the inner surface of the elements. You need to remove the tire carefully, as there is a possibility of piercing the camera. When pumping it with air, it is important to take into account the permissible pressure (it is indicated on the tire).

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.

How to change the camera in a bicycle wheel | Replacing the camera

Probably the most common breakdown for a cyclist is a puncture of a wheel, especially if he is riding in an aggressive style. It ran over the glass, then on a nail, and sometimes jumped over the curb at speed. Experienced cyclists can change the camera in a bicycle with their eyes closed, but what about a beginner who cannot even remove a wheel, not that the camera should be changed?

The main thing is not to despair if you travel a long distance (or better always) carry a pump, a spare chamber or, in extreme cases, a “bicycle first aid kit” for the wheel. Someday she will save you from the fate of pulling the bike “on her”.

So, if you have a punctured wheel, first you need to get off the bike, in no case continue to move on a flat tire. Firstly, you will tear the tube even more, secondly, you can ruin the tire, and in the worst case, also the rim.

Bicycle camera repair and replacement

To repair punctures in the wheels of a bicycle, you first need to make sure that the wheel is really damaged. This can be evidenced not only by an eight (see the article “How to fix an eight on a wheel”) and a large hole in the rubber, but also by the faint sound of air coming out. To check, inflate the wheel and inspect it carefully to be sure. which does not allow the nipple to pass. If the reason is in it, then tighten it tightly.

If it does not help, then it means that the camera will have to be changed because of the nipple. If everything is in order with the nipple, and the wheel continues to deflate quite noisily and quickly, then it is not difficult to find the air outlet by ear.

Cycling camera repair: preliminary inspection

In case the camera is punctured, it is necessary to carefully inspect the tire at the puncture site so that the culprit of the puncture does not remain. If you find a hole on the inside of the tube instead of the outside, then we advise you to inspect the rim. If you have single rims on your bike, the tube may be punctured with a spoke.

See that there is nothing sharp on the rim, and that the flipper is intact. this is a special rubber band that covers the ends of the spokes on the rim. The flipper must be replaced if it is torn. Usually it does not break just like that, so you need to find what could break it on the rim and align it with a file.

This happens extremely rarely and usually concerns a factory defect that was not noticed during the assembly of the wheel.

Changing the camera: disassembling the wheel

Then bleed all the air from the wheel and unscrew the cap from the nipple, as well as the fixing washer at its base in case they are. Then pick up the bead of the tire with a spatula and turn it out. And at the other end of the shoulder blade, hook on the knitting needle. The same should be done with another scapula at a distance of about 15 cm from the first scapula. If there is a third paddle with the help of it, it will be enough just to pry off the tire, and then it can be easily removed by hand. As a last resort, small wrenches will do (see picture). The only thing is that you will need to hold them well so that they do not hit in the forehead. The other side of the bike tire does not need to be removed, since the camera is already taken out without much difficulty.

How to find holes on the camera?

Pump up the camera in such a way that it will slightly increase in size and, adding water to the container (bucket or basin), carefully examine the entire surface of the camera under water for holes. In the chamber, a hole can be detected immediately by a thin stream of bubbles emerging from it. After finding one hole, do not end the inspection at this until you have checked the entire chamber, so as not to repeat it all over again.

The chamber can also be leaky from a breakdown, and not just from a puncture. The bike tube can be punctured by bumping into a curb, rail or large pothole at speed. In this case, you can find 2 holes on the camera at once in the form of short cuts parallel to each other. So you can very easily get an eight on the wheel. To prevent this from happening, a stronger inflation of the wheel. 2.5-3 atmospheres can also help.

Bicycle camera repair: patching holes

To seal the holes, it is preferable to use an old cycle tube. It is necessary to cut out a small circle with a diameter of 1.5-2 cm. And if the hole is large, then even 3 cm. The main thing is to remember: the larger the patch, the worse it will hold. It is necessary to process the patch and the puncture site with a fine sandpaper: the rougher the surface, the better it will adhere.

It is best to sand the patch before cutting it out. Degrease the sanded surfaces with vodka or alcohol. It is better to do this with cotton swabs because they do not leave fibers. And you do not have to blow to dry, as the exhaled moisture worsens the adhesion. In order to make it convenient to work with the patch, and also not to touch its treated side, you need to stick it on a piece of plaster or electrical tape.

Let’s talk about what kind of glue is best for gluing. To be honest, choosing a good glue is as difficult as choosing the right bike for a child, there are many aspects and pitfalls. Of the instant ones. the best are “Super Attak Gel” (German company “Loctite”), “Super Glue Extra” (“HI-TECHO”), and “Super Moment Gel” (Russian “Era”). To glue them, you need to have a certain skill: apply no more than the required amount of glue, accurately apply a patch, press it quickly and firmly. Only the patch needs to be smeared with instant and second adhesives. On the packaging it is written in detail how to glue them. Use glue when time is running out.

Better to use adhesives that work after 12 and 24 hours. The best glue among daily allowances is “88-CA”. Also good are “88-NT”, “Sprut” and “Master”. We recommend the “Radical” glue from those that dry in 12 hours. Moment glue produced in various variations can come off. Any of these adhesives are applied in a thin, even layer around the hole to the camera and patch. To make it easier to get in, you need to apply a glue spot about 2 cm larger than the diameter of the patch on the camera. Before pressing the glued surfaces, some of the adhesives need to be dried, which is indicated on the package. Then you can patch the hole so that the hole is under the center of the patch. Then cover the top with a piece of paper and place under a press. For example, you can press the camera with a clamp to a flat surface of a window sill or board.

Insert the camera into the wheel

That’s it! Depending on the adhesive, after 12 or 24 hours, you can gently try to pull the patch off. If already held, then the camera can be inserted back into the wheel, starting with the nipple. Tuck the tire into the rim so that the camera does not get between them. If it is not possible to fill the tire to the end, then you can use the eccentric lever or mounting. Put the wheel on the bike and tighten the gulls or eccentric.

If you have a v-brake, then you need to close it so as not to be left without a brake, it may need to be adjusted. Inflate the wheel slightly and remember the tire well with your hands along the entire length so that the tube fits well. Now you can pump up the wheel to the end.

Replacing the camera on a bicycle: removing the rear wheel

If the rear wheel is damaged, then you need to put the chain at the back on the smallest sprocket (I recommend that you study the article “Changing the chain on a bicycle”) so that it is not difficult to assemble later. If your muantine bike has a brake similar to the v-brake type, then you need to open it by bringing the brake levers together with your hand and remove the arcuate metal tip of the shirt from the groove, where the cable comes out.

Next, turn the bike over. In order not to stain or scratch anything, place rags under the seat and under the steering wheel. If the wheel is secured with bolts, then it is necessary to unscrew it with the appropriate keys. If it is normally attached, then you need to unscrew the eccentric, for which you need to bend the lever and turn the nut on the opposite side (do not unscrew it completely) and remove the wheel.

And the rear wheel can be removed more easily if you bend the rear derailleur tab so that the roller closer to the cassette stars is not pressed against them. You will understand that if you do not do this, then the eccentric of the hub from the wheel will bury exactly in this place.
