What is the best glue to use?
The glue must be compatible with rubber, be waterproof, maintain strength under conditions of increased pressure, and have convenient packaging. An important characteristic is the polymerization period of a particular adhesive.
If the repair is not urgent, then you can use long-drying adhesives, for example: “Sprut” (40 rubles / 50 ml), 88-CA (50 rubles / 60 ml), “Moment-1 Classic” (110 rubles / 50 ml ). The listed formulations dry out within a day and are inexpensive. However, they are not suitable for urgent repairs. Once glued, the bike cannot be used for 24 hours, which is not always acceptable.
For instant elimination of air leaks and repairs in the field, quick-drying adhesives are more suitable: Loctite Super Attak Gel (300 rubles / 3 ml) and its domestic analogue Super Moment Gel (50 rubles / 3 ml). The advantage of these formulations is polymerization within 5 seconds. The disadvantage is higher cost for less volume. In addition, the use of such superglue requires a certain skill, since an incorrectly applied patch will instantly adhere to the camera, and it will not be possible to re-glue it.
How to use the repair kit?
An example of a complete set of a Chinese-made repair kit:
- portable case;
- a set of keys of different sizes;
- accessories for removing the tube from the tire;
- a tube of glue;
- a device for cleaning the tire surface;
- large, medium and small patches.
Sets of this type cost from 500 rubles. They are equipped with tools that allow you to repair the bike yourself without resorting to the services of a workshop. A simplified repair kit consists of a set of patches, glue and sandpaper to clean the puncture site. It costs less.
- Park Tool Vulcanizing Patch Kit for 280 rubles. Contains 4 round (25 mm diameter) and 2 oval (25 × 35 mm) patches, glue, sandpaper.
- “Lezyne Smart Kit” at the price of 290 rubles. Consists of a sheet of sandpaper and 6 patches coated on one side with a super sticky adhesive layer.
- Park Tool Super Patch Kit for 360 rubles. Contains a sheet of sandpaper and 6 self-adhesive patches with a diameter of 25 mm.
- Green Cycle YC-129A for 278 rubles. Contains a tube of glue, sandpaper, hooks for removing the tube from the tire, round patches.
- dismantle the wheel;
- remove the tube from the tire;
- find and mark the place of damage;
- release air from the chamber;
- clean the surface of the chamber at the puncture site until the dirt is completely removed and a black matte color is obtained;
- apply a thin layer of glue to and around the hole;
- print the patch, being careful not to touch the orange degreased side with your fingers;
- apply the patch with the grease-free side to the area greased with glue and press down with your fingers;
- remove the protective film from the outside of the patch;
- wait for the glue drying period specified in the instructions;
- inflate the tire and check the tightness.
How to find the puncture site of the camera?
First of all, you need to find and mark the location of the air leak. To do this, remove the wheel from the bicycle and remove the tube from the tire. Large defects can be seen on visual inspection. They help to detect the whistling of air coming out of the hole.
However, situations are even more complicated. What should a cyclist do if he stumbles upon a scattering of thorns and damages the camera in several places? There are several ways to find punctures in this case:
- With water. This method is used if there is a nearby container with water or a reservoir. The inflated bicycle tube is immersed in the water completely and you watch where the air bubbles come from. Places found are marked with a ballpoint pen.
- The tactile way. The section of the camera where the hole is supposed to be is brought up to the face. The sensitive skin of the face or lips is better able to sense even small leaks, from which air escapes silently.
- Using foam. The soap solution is whipped, the resulting foam is applied to the surface of the tire. Instead of soap, you can mix dishwashing detergent or shampoo with water. Damage points can be found by rapidly expanding single bubbles.
- With the use of powder. The surface of the chamber is sprinkled with powder, talc, flour, starch or other fine powder. In field conditions, it can be replaced with fine dust. At the site of damage, the escaping air will blow away the powder.
- release the brakes on the wheel to be repaired;
- release the eccentric;
- remove the wheel using a wrench and lay it horizontally;
- lower the bike to the ground with its left side down, so as not to damage the speed switch;
- bleed off the remaining air from the chamber by opening the nipple;
- hook the edge of the tire over the side with one of the plastic dismantling blades;
- using the second paddle to remove the tire in a circular motion;
- pull the camera out from under the free edge, trying not to displace the tire relative to the wheel rim;
- inspect the tire and feel it with your hands in order to find the spikes, glass fragments or other sharp objects that caused the puncture.
The next step is to repair the camera in one of the following ways:
- repair kit;
- planting self-made patches on glue;
- temporary repairs using scrap materials;
- the imposition of a liquid patch or sealant;
The sealed tube is then checked for leaks and inserted back into the tire. This is done like this:
How To Fix A Bicycle Hole
- insert the camera nipple into the hole in the wheel rim;
- moving in a circle, tuck the camera into the tire with your hands;
- pump up the camera a little, about half;
- fill the previously disassembled edge of the tire under the rim;
- make sure the tube and tire are in the correct position;
- pump up the chamber to the pressure recommended by the manufacturer;
- install the wheel;
- twist the eccentric;
- fasten the brakes.
How to glue a bicycle camera at home and is it possible to do without glue?
All bicycle owners are familiar with the situation when a tire suddenly blows out. This trouble usually happens at the most inopportune moment and can disrupt plans. In the past, the most reliable solution was to repair the chamber using vulcanization in specialized workshops. Now there are new materials that have greatly simplified the repair procedure. Now you do not need to carry your bicycle tube to the workshop, you can glue it yourself. We will discuss what will be needed for repairs and what is the best way to eliminate air leakage if at the time of damage a person is far from home.
How to prevent punctures and tears?
It will not be possible to completely eliminate the likelihood of punctures, but there are several ways that can reduce the number of damage and repairs. Preventive measures are as follows:
- choose tighter tires, such as road tires;
- buy tires with an anti-puncture layer;
- timely change worn-out rubber to a new one;
- install a tube that matches the size of the tire or slightly larger to ensure a snug fit;
- do not use cameras longer than the prescribed expiration date (from 3 to 4 years);
- do not ride unnecessarily over rough terrain, and overcome suspicious areas on foot, driving a bike nearby.
What can you make a bicycle camera patch from at home??
These types of repairs do not guarantee long-term results, but they are not required to do so. The purpose of the temporary patch is to seal the puncture and make it possible to get on the damaged bike to the house or another place where you can make high-quality repairs.
- plastic wrap tied tightly around the damaged area;
- insulating tape;
- medical plaster;
- a piece of cardboard, rubber or PVC cloth, planted on double-sided tape.
After the camera is repaired in this way, care should be taken to ensure that the temporary patch does not move from its place. To do this, the camera is placed in a tire and inflated more than usual. Excess air inflates the chamber and strongly presses its walls, including the patched area, to the inside of the tire, preventing it from moving while driving.
Glue the patch
Then stick the patch firmly against the camera. It is best to press it down with something heavy for about five minutes, until the glue is completely dry. Pay special attention to the edges of the patch, the glue should grab evenly over the entire surface. If there is tape on top of the patch, it is best to keep it. this will help prevent the patch from sticking to the inner surface of the tire.
Don’t glue a large patch on a narrow camera.
How to glue a bike camera
No matter how dodgy your bike is, no one is safe from a puncture in the middle of the road. It is advisable to always carry a pump, patches, glue, a set of editors, a felt-tip pen, a grout or a piece of sandpaper with you.
So, if you feel that the wheel is deflating, examine the tire tread for any sharp objects stuck in it. If you find a piece of glass or other object sticking out, carefully remove it and try to remember the place where it was. In the future, this will help find a puncture in the chamber faster. In some situations, the puncture may not be from the top, but from the bottom of the chamber, the reason for this may be the spoke heads or the spokes themselves sticking out through the rim tape.
Check the inside of the tire
After removing the tube, be sure to check the inside of the tire for any stuck sharp elements.
Prepare your camera
Take a grout or a piece of fine emery paper and sand the surface of the camera where you will glue the patch until it is dull. Remove the protective foil from the bottom of the patch. Hold the patch around the edges, being careful not to touch the adhesive surface with your hands. Apply a small amount of glue to the puncture site itself and to the patch. Rub it evenly with a tube and wait a couple of minutes until the glue thickens and acquires a characteristic matte shade.
It is best to use rubber glue, the one that comes in the kits of all bicycle first aid kits. We do not recommend using superglue and other second-hand glue, as they corrode rubber and, when dried, stand up like plastic. You can also use self-adhesive, where you do not need to fiddle with tubes of glue, but they tend to be more expensive, and there are fewer in the set.
Take off your camera.
Now you need to get the camera out of the tire. If your wheel is not eccentric, then you will also need keys to remove it. You can get the camera without removing the wheels from the bike, but it will be less convenient to glue it this way. It is worth remembering that it is not always possible to disassemble the wheel by hand with ease, so plastic assemblies will come in handy here. Never use screwdrivers, hex keys or other wrenches. it may damage the camera.
Pump up your camera
After taking out the camera, pump it up and examine it to find the puncture site. This can be done in different ways. If the hole is large, then it can be detected visually, if it is smaller, then it is better to bring the camera to your face in order to feel where the air is poisoning. In some cases, if the puncture is completely invisible, and the wheel is deflated every 1-2 days, then you can find it by lowering the camera into the water. air in the form of bubbles will ooze at the puncture site. After finding the puncture site, circle it with a marker. This is optional, but lowering the camera will make it easier to spot the puncture.
Install the tire
Once you have glued on, you can insert the camera back into the wheel. Gradually inflate the wheel, checking if the court of the tire is level with the rim, if the tube is lowering. Perhaps the patch did not adhere well or you missed another hole, it happens. If all is well, the tire is still and the wheel does not deflate anymore, put the wheel back on the bike and forward. let’s hit the road!
Finally, it is worth adding that if you make your way very often, then perhaps the protector of your tire is badly worn out and it is time to replace it. And carry a spare camera with you.
How to stick the patch correctly
Despite the fact that using a patch to repair punctures is not the most reliable and effective way to fix a camera, it is still worth being able to use it.
You will need any kind of rubber glue. To make the right choice when buying, it is worth knowing in advance which manufacturers create glue that does not burst on bends. All you have to do is simply glue the breakage area.
Home repair of a camera is quite real. To implement it, a minimum of tools and knowledge are required. It is enough to take a responsible approach to the issue and study all the steps. Of course, it is much more useful to monitor the wheels and the road before the accident, but in the event of a breakdown or damage there will be no problems and going to a workshop or a tire fitting service is almost never needed to seal the hole.
Emergency: Notes for the Cyclist
In the event of force majeure, the real proceeds will be a special repair kit with express patches. The kit will help you quickly troubleshoot and continue your journey. In the absence of a bicycle first aid kit and suitable equipment for sealing the hole in the chamber, it is necessary to inflate the tires to five atmospheres. The high pressure will press the tube against the tire, and therefore the air will escape from it more slowly. This will allow you to get to your destination and start repairing in the future.
To protect yourself from such troubles, you can use a special anti-puncture fluid (sealant) for bicycle cameras: when a puncture occurs, it instantly fills the puncture area and hardens upon contact with air. It is enough to spin the wheel several times, pump it up, and you can continue on your way.
Removing the camera
Usually the most difficult step is to get the camera out of the assembled wheel. With the skill and the right tool, it’s very easy.
The wheel can be disassembled using edgers or any flat objects. screwdrivers, keys, even coins:
- We completely lower the camera on the bike. To do this, unscrew the spool from the nipple. On good rubber, this can be done using a groove in the cap; on cheap models, you have to hold the spool with your hands until all the air is released. In some cases, this step will have to be done before removing the wheel, as the wide XC rubber will cling to the brakes and frame.
- Choosing a place on the back of the bicycle wheel from the nipple to start disassembling.
- We drive the bead between the rim and the tire vertically down, trying not to touch the camera inside.
- We retreat 10-15 centimeters from the first, drive the second.
- Carefully, like levers, lift the tire until a small segment is behind the outer part of the rim.
- Next, we remove the rest of the tire with our hands.
- Carefully remove the valve from the groove in the rim, take out the camera.
The result of all actions is a disassembled wheel, with the tire “put on” over the edge of the rim, and a free tube, ready for repair.
How to replace a bike camera while walking
So, now going on a long bike ride, you will be aware of the need to have a basic set of tools with you. over, prepare an additional replacement in advance if the rubber on the wheel becomes unusable due to certain road accidents. If the camera is punctured, you can quickly replace the punctured rubber. Also check out the algorithm for removing a bicycle tire:
- Unscrew the fixing nut or loosen the technical eccentric;
- Clean the components of the removed wheel from dirt and dust;
- With chalk, mark in front of the chamber spool;
- Remove the spool: when you press the nipple, you need to release so much air so that the tire moves freely from the rim;
- Using the assembly, pry off the cover, remove it.
Be careful: the rubber should not fall into the gap between the mounting and the rim, otherwise it may be damaged;

How to change the camera in a bicycle wheel | Replacing the camera
Probably the most common breakdown for a bike lover 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 on a bike with their eyes closed, but what about a beginner who can’t even remove a wheel, not that a camera change. 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.
How to change the camera on a bike
1) If the wheel is not fully lowered, lower it to the end, for this unscrew the cap of the nipple (spool). If you have a nipple (spool) (the same as in the car), press something sharp on the small button in the middle and hold until the wheel is deflated. If you have a spool key cap, simply unscrew it. If you have a nipple (spool) (such as in old bicycles), unscrew the thumbscrew and remove it.
2) Remove the wheel. If the wheel is on an eccentric, removal will not be difficult, if not, then you will need keys (depending on the bike and wheel 13-17).
3) If you have “assemblies”, use them to remove the rim from the wheel, if there are no assemblies, you can use a handy tool (wrenches, etc.), but it is advisable not to use objects with a sharp edge. this can damage the camera or rim. Pry the tire with your tool and push it against the rim until the edge of the tire crawls out of the rim, then take the second key or assembly and do this action again, while DO NOT take out the first key when you feel that the keys do not lean back when you release them. just try to draw the second key in a circle around the side of the first key.
4) Take out the camera by simply grasping it with your fingers. Take on the opposite side of the nipple (spool).
How to Patch a Bicycle Inner Tube
5) In principle, you can insert a new camera, but I recommend removing the tire completely (this can be done with your hands or with assemblies (keys)). And check the condition of the rim if there are any metal burrs inside, check the condition of the rim tape, view the inside of the tire. (This action is especially necessary if you change cameras very often and do not know where you could punch a wheel)
How to install a camera in a bicycle wheel
1) Take a new camera or a sealed one (how to glue a camera), squeeze it with one hand and slide it in a circle. this will help to clean it of unwanted foreign objects (pieces of rubber, metal shavings, etc.)
2) Inflate it slightly, if you removed the tire completely, put it on one edge (if the rubber is directional. make sure you install it correctly (you can see it on the rear wheel if the protectors are the same)). Mark approximately where the hole from the nipple (spool) is to put the camera into the tire without twisting or breaking it. Insert the spool (nipple) into the hole and screw on the cap.
3) With your hands (if the tire is soft) or using the same tool, put the second edge of the tire onto the rim. BE CAREFUL if using the tool, do not tear the camera.
4) Immediately inflate the wheel slightly and roll it so that the camera settles down, then inflate the wheel to the desired pressure (how to find out how much pressure you need to inflate the wheel)
5) Put the wheel on the bike and clamp it.
3) Nipple as in old bicycles (German)
Dismantle the wheel
The first thing to do is to remove the wheel with the damaged tube. To do this, you will have to do the following:
- Disconnect the brakes, if they are rim, fenders, if they can interfere with the work with the wheel.
- Flip the bike.
- We unscrew the retaining bolts on the bushing or eccentrics.
- We carefully take out the wheel. In case of problems with the rear wheel, it is most effective to hold the chain, first move the wheel axle towards the saddle, and then, lifting it, pull it out.
Now nothing interferes with working with the wheel, you can proceed to further steps.
There is also an extreme case when in a problem situation the rider is left without glue and tools, for example, a puncture was received while riding around the city, but you still need to get to the house. In such situations, there are also ways out. For example, the chamber is cleaned and a patch is applied to it in such a way that when the inflation is strong, the pressure presses the patch.
Otherwise, if there is no patch, tape or a wetted plastic bag is used. In case of situational repair by “applying” the surfaces are not cleaned with emery, but on the contrary, they are wiped as smoothly as possible so that there are fewer gaps.
Of course, all these methods are temporary, and they only work for a short time, subject to strict restrictions:
- The contact surface must be clean and smooth.
- Shock loading of the wheel is prohibited.
- The pressure must be constantly monitored and kept at maximum.
Alternative repair versions
There are situations when there is no repair kit with you. It is impossible to predict everything, but we will give a couple of recommendations:
- The patch can be made from any rubber, including an old camera, automotive or technical rubber.
- What kind of glue to use is not very important, as long as it is intended for rubber. It is better not to use hardening industrial and household compounds.
- We clean the surface from grease with acetone or gasoline, in the field. with a clean cloth.
- We go around the surface with sandpaper (not necessary, but a useful step for gluing quality).
- Remove the protective film from the patch.
- Apply glue, according to the instructions on the tube, on one or two surfaces at the same time.
- Press the patch firmly against the camera and hold it, trying not to move the parts relative to each other.
Then it remains to wait for the “setting”, which occurs, depending on the description, either immediately or within 5-15 minutes. In modern repair kits, the glue is usually quite fast, but at home you can also use the classic “Moment”, which will take several hours to harden. How to glue correctly is described in detail on the packaging of the tubes inside the repair kits.
In addition to using non-specialized adhesives, the patch itself can be made from an old camera. The main thing is that the rubber is intact and well cleaned.
The glueless method that comes from the automotive world is vulcanization, which is also used on a bicycle. Requires special equipment, but reliably repairs punctures. The essence of the vulcanization process is that the peeled patch and the chamber are pressed against each other with great force and heating, in fact, they are fused, forming a single structure.
How To Fix A Bike Puncture. Repairing An Inner Tube
Vulcanization is much more reliable than any adhesive patches, but requires skill and additional equipment. By the way, there are “household” or home-made vulcanizers, consisting of a vice with a cylinder and a chamber for burning, for example, gasoline or other fuel. The only advice that can be given is to be careful with fire.
How to properly glue a bicycle tube?
In the event of a puncture or other damage, it is rare which professionals help to seal the bike camera, and the riders have to do everything with their own hands.
How to properly glue a bicycle tube and repair a tire
How to glue a bicycle tube:
Before installing the tube, double check the inside of the tire to determine the cause of the puncture. Once, after driving along a road along a river dotted with thorns from a hedge, I found about a dozen thorns! By matching the tube and tire, you can find the puncture site. Carefully run your fingertips around the inside of the tire to find the items that caused the puncture and remove them.
- When removing the tube from the tire, remember in which direction the tube was placed in the wheel. This will help locate the puncture site in the chamber after locating the puncture-causing object in the tire.
- Use a ballpoint pen to mark the puncture site with a cross so that you know it exactly.
- If you don’t have sandpaper, stone and pavement can be used instead.
- To prevent the beads of easily inflated tires from falling into the rim groove on one side and swelling on the opposite side, install a thicker rim tape or two rim tapes.
- To make it easier to remove and replace tight tires, install the rim tape as thin as possible.
- Follow puncture repair techniques carefully. The latter need to be installed on the rim section of the tire at the point where the nipple is attached. Make sure the tire beads are as deep as possible into the rim groove. When installing some hard tires, beads are indispensable. Use the special VAR 425 bumpers to help prevent puncture of the camera during installation.
Two small side-by-side holes in the tube indicate a snakebite that occurs when the tube is pinched between the tire and the rim when driving over a sharp object. Also, these punctures are often caused by under-inflation of the tire to the recommended pressure. Make sure the sidewall of the tire is intact. Otherwise, you cannot do without urgent tire repair.
The hole on the inside of the chamber indicates that the spoke head is to blame for the puncture. Check the entire length of the rim and make sure the spoke holes are covered with rim tape and the ends of the spokes do not protrude beyond the inner surface of the rim. If they protrude, then they need to be filed.
A less common cause of puncture is the rough edge of the nipple hole. This puncture is located at the base of the nipple and it is not possible to glue the bicycle tube.
Create your own camera repair kit:
- Several patches;
- Rubber glue;
- A pair of plastic edging;
- A piece of good sandpaper;
- Small adjustable wrench (when using wheels with hex nuts);
- Or a hex wrench (when using wheels with hex nuts);
- Reliable pump;
- LED keychain (useful when using a dynamo);
- A pair of spare tires (always carry with you).
Everything except the pump must be packed in the seat bag.
Check your bike tires weekly for cuts, sidewall bulges, and wear. Tires with cuts, bulging, and tires with skin visible through the tread are not subject to further use. Remove any pebbles or glass you find embedded in the protector. Use a pressure gauge to check the tire pressure. Tires inflated to the recommended pressure will puncture less frequently and last longer. Recommended pressure is usually indicated on the sidewall of the tire.
Bring spare cameras and tires with you.
In the rain, it is very difficult to glue the bike tube, as the patch will not be able to stick to the tube. In such a situation, you need to install a spare camera, which you should always carry with you! A spare tube will also be indispensable in the event of a tire bulging out of the rim or puncture at the nipple attachment point.
Urgent bicycle tire repair.
Fold a large piece of sturdy plastic in half. Trim the section to a size 10 cm wider than the cut and 5 cm wider than the tire. Remove the tire from the rim. Place a double layer of patch in the center of the gap or cut within the sheathing. Holding the emergency patch, which should protrude on both sides of the tire, install the first bead of the tire on the rim.
If necessary, install a new camera and pump it up a little. Install the second bead of the tire, with the last to install the glued section of the tire. Make sure the patch adheres to both sides. Inflate the tire and cut off any extra patch that should hold perfectly in place thanks to the tire’s air pressure.
