Glue for bicycle chambers. After that, we look to ensure that the patch adjoins the camera evenly and that there are no unglued edges. If they are, then you need to add glue with the tip of the tube and press it. If there are places that are not glued along the edges, then the repair will be considered

No matter how evasive 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 montages, a felt-tip pen, grout or a piece of sandpaper with you.

So, if you feel that the wheel is flat, examine the tire tread for sharp objects stuck in it. If you find a protruding piece of glass or other object, carefully remove it and try to remember the place where it was. In the future, this will help to quickly find a puncture in the chamber. In some situations, the puncture may not be on the top, but on the bottom of the tube, the reason for this may be the heads of the spokes or the spokes themselves sticking out through the rim tape.

1. Remove the camera.

Now you need to get the camera out of the tire. If your wheel is not on the 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. It is worth remembering that it is not always possible to easily disassemble the wheel manually, so plastic pryers will come in handy here. Never use screwdrivers, hexagons or other wrenches - this may damage the camera.

2. Check the tire from the inside

After removing the tube, be sure to check the inside of the tire for any stuck sharps.

3. Pump up your camera

Take out the camera, pump it up and inspect to find the puncture site. You can do this 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 poisons. In some cases, if the puncture is completely imperceptible, and the wheel lowers every 1-2 days, then you can find it by lowering the camera into the water - air will ooze in the form of bubbles at the puncture site. After finding the puncture site, circle it with a marker. It is not necessary to do this, but lowering the camera back will make it easier for you to find a puncture.

4. Prepare your camera

Take a piece of grout or a piece of fine sandpaper and smooth the surface of the camera where you will glue the patch to a matte state. Remove the protective foil from the bottom of the patch. Hold the patch along the edges, being careful not to touch the adhesive surface with your hands. Apply a small amount of glue to the puncture site and patch. Rub it evenly with a tube and wait a couple of minutes until the glue thickens and acquires a characteristic matte shade.

Glue is best to use rubber, the one that comes in the kits of all bike kits. We do not recommend using superglue and other instant glue, as they corrode rubber and, when dried, stand up like plastic. You can also use self-adhesives where you don't have to fiddle around with tubes of glue, but they tend to be more expensive and there are fewer in the set.

5. Apply the patch

Then apply the patch, pressing it firmly against the camera. It is best to press it 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 a film on top of the patch, it is best to save it - this will help prevent the patch from sticking to the inner surface of the tire.

Do not glue a large patch on a narrow chamber.

6. Install the tire

After you have glued, you can insert the camera back into the wheel. Gradually inflate the wheel, checking whether the tire court has risen evenly into the rim, whether the tube is lowering. Perhaps the patch did not adhere well or you missed another hole, this happens. If all is well, the tire has risen evenly, and the wheel is no longer flat, put the wheel back on the bike and go!

Finally, it is worth adding that if you break through very often, then the tread of your tire may be very worn out and it is time to replace it. And carry a spare camera with you.

The chamber is the part of the wheel that contains air under pressure. A small hole is enough for air to escape from the chamber and the bike is no longer serviceable.

The main reasons for a puncture can be:

collision with a bicycle wheel on a sharp object;
pinching the camera between the rim and the tire;
wheel spoke impact;
rough, hard end of the nipple hole.

What you need to prepare - the choice of inventory for repairs

To save money on buying a new camera, you can do a simple repair. It will be within the power of every owner of two-wheeled vehicles.

To do this, you should use some tool and a special repair kit.

So, you will need:

hex heads and wrenches for dismantling the wheel;
mounting blade to bend the tire away from the rim;
sandpaper;
a large container of water (basin or bucket).

The repair kit includes:

glue;
rubber patches.

What glue can be used?

The repair kit can be bought in special stores, or you can make it yourself.

Rubber patches are cut from the old camera, and the glue is selected separately. The cost of one repair kit for a bicycle varies within 90 rubles.

VIDEO INSTRUCTION

Seal the bike camera with a repair kit

Preparation for work.

Install the bike in the mounting position: turn it over and fix it.
Nearby, preferably in a conspicuous place, for example, on a table with lighting, lay out tools and materials.

Wheel removal and inspection.

Using the necessary tools, remove the wheel from the bike.
Fix it and carefully inspect the entire tire for damage. Use gloves to avoid accidental injury from glass shards or a self-tapping screw that is stuck in the tire.
Even if you know exactly where the puncture is, do a full inspection of the tire without missing an inch.

Tire dismantling.

Insert the previously prepared mounting blade between the rim and the tire. Push the nipple inward first.
Gently pull the paddle towards you and separate the tire from the wheel.
Note! On some bikes, the tire can be removed by hand with just one pry bar.

Camera Diagnostics.

Remove the tube and inflate it using a bicycle pump.
Place the camera in a container of water and observe carefully. In the place where air bubbles appear, there is a puncture.
Note! Sometimes it seems that there is only one damage, and during the diagnostics it is possible to detect several of them.

Sealing the camera.

Using sandpaper, roughen the surface around the damage.
Apply a little glue to the treated surface and spread it evenly. Wait until it dries completely.
Apply a second layer of glue in the same way and let it dry completely again. How to check if the surface is ready for further work? If the glue dries, it will be matte.
Apply a third layer of glue and attach a patch to the puncture site. Or, if you have a store-bought repair kit, remove the protective film from the patch and attach it to the tire. Press hard or apply a press.

Camera and wheel installation.

Install one side of the tire on the rim.
Pump up the camera, but not completely. Install it in its seat in the rim.
Gently slide the second bead of the tire under the rim along the entire diameter of the wheel with your thumbs.
Pump up the camera. The bike is ready for use.

How to solve the problem quickly without glue

Sometimes, a puncture needs to be fixed in conditions where glue and rubber patches are not at hand. For such cases, there is an old, old-fashioned method proven over the years.

Turn the bike over and secure it.
Locate the puncture site on the chamber.

This can be done during the inspection. You can also press your hands on the tire and listen. The air coming out of the puncture will make itself felt with a hissing sound.

Bend one side of the tire away from the rim near the puncture site and remove the tube and tie it in a knot.
Place the tire beads under the rim and inflate the tube.

Where to begin? Determine the puncture site

The most common causes of a tube puncture are tire wear and off-road driving. Although in fact there are much more reasons. The banal culprit for the appearance of a hole in the chambers can be riding on a flat tire, which will lead to tire and rim wear, the repair of which is much more difficult and expensive than repairing the chamber.

Before proceeding with gluing, you should make sure that there is a puncture and determine its very place. To do this, you need to pump up the wheel, tighten the nipple well and determine by ear where the wheel passes air.

The next step is to unscrew the wheel. To do this, the bike should be placed on the handlebars, after placing a protective base under the seat to prevent scratches and dirt. When unscrewing the rear wheel, put the chain on the back of the smallest sprocket. This will greatly simplify the procedure for its assembly after repair. The presence of a v-brake type brake pad provides for its opening by arching the brake levers and pulling the metal arcuate tip of the shirt out of the groove. If the wheel is fastened with bolts, unscrew them. With normal fastening, it is worth unscrewing the eccentric by bending the lever and turning the nut in the opposite direction.

After the wheel is removed, proceed to disassembly:

lower the wheel;
with the help of a pry bar, we hook up the bead of the tire and turn it outward, attaching the other end of the pry bar to the knitting needle;
at a distance of about 20 cm from the first shoulder blade, repeat the procedure;
remove the cover by hand.

If there are no tools at hand, try to do it on your own. A short video guide will help you:

After taking out the camera, you should pump it up and put it in a sink with water. The presence of holes in it will be seen by a thin stream of air in the form of bubbles. If the damage is very small, it is necessary to squeeze the chamber by hand, increasing the pressure in it. This will lead to a faster release of air from it. Holes in the chamber can be caused not only by a puncture, but also by a breakdown. In the latter case, several short parallel cuts will be observed. It is important to carry out a thorough inspection of the tire for the presence of various kinds of stuck objects in it that can cause a second puncture.

How to seal a bicycle inner tube: step by step instructions

There are three options to help fix a broken camera:

Replacing a punctured chamber with a new one.
The use of a special repair kit, which includes ready-made self-adhesive patches and other equipment. To eliminate the hole, you must follow the instructions that come with the kit. Often it will be necessary to clean and degrease the damaged surface well, and then glue the patch.

Self-repair involves the preparation of all the necessary equipment with his own hands. This is a more labor intensive process. But if you follow the whole procedure in stages, difficulties should not arise.

What you need for self-repair

old camera
Fine sandpaper
Alcohol

The procedure for sticking the camera with your own hands is as follows:

- after determining the location of the damage, its size should be estimated for the preparation of the patch. It is better to cut it out of the old chamber in the form of a circle, up to 2 cm in diameter. If a hole is found on the chamber, a patch with a diameter of up to 3 cm will be required. The larger the patch, the worse it will hold. Therefore, it is important to fit it exactly to the size of the damage. Before cutting out the patch, you should first sand the old camera, degrease its surface with alcohol and stick a piece of electrical tape on the side that will be glued. This manipulation will save the patch from pollution;

clean from dirt, sand and degrease the puncture site itself;
apply a thin layer of glue to the patch and the chamber around the damage, wait for the time specified in the instructions for the glue. Rubber glue "Moment" provides 10-15 minutes. expectations;
apply a patch to the damaged area so that the hole is in its center. It is important that the patch lay down in an even layer without the formation of air under its surface;
cover the place of repair with paper and put the camera under the press for 12-24 hours.

Wheel reassembly

After the tube has dried, you should install it in the tire. In order to facilitate this process, it is necessary to slightly pump it up, insert one edge, and then fill the rest. A correctly installed tube should not protrude beyond the tire, and the air valve should point inward. We fill the tire into the wheel rim using the eccentric lever or the mount. Please note that some tires are designed for rotation in one direction, which will be indicated by the corresponding arrows on their sides. Therefore, it is important to install the tire clearly on the indicated course in order to avoid its rapid wear.

Having pumped up the wheel, you can install it on the bike by tightening the eccentric or seagulls. At the same time, the presence of a v-brake brake system will require its adjustment.

What glue to choose?

When choosing glue to eliminate a hole in the chamber, it is first necessary to analyze the situation and determine the most effective option. According to its properties, glue can be divided into four categories:

per diems that require the patch to be kept under pressure for 24 hours;
mounting - provide complete drying after 5-12 hours;
fast-acting - guarantee the possibility of using the glued surface after 30 minutes;
instant action. The adhesive of this group is quite convenient to use, since it provides for application to one surface and does not require drying time before gluing.

Emergency: a note to the cyclist

In case of force majeure circumstances, the real proceeds will be a special repair kit with express patches. The kit will help you quickly troubleshoot and continue on your way. In the absence of a bicycle first-aid kit and suitable equipment for sealing a hole in the chamber, it is necessary to inflate the tires to five atmospheres. The high pressure will press the bladder against the tire, causing the air to escape more slowly. This will allow you to get to your destination and then proceed to repair.

How to seal a bike inner tube:

1. Find a puncture.
In order to find the cause of a puncture, check the tire all the way from the nipple. Remove any glass shards or pebbles you see. Even if you find a possible cause of a puncture, still check the tire to the end.
2. Remove the camera.
Release the air. Push the nipple into the tire. If there is a ring on the nipple, unscrew it and store it in a safe place. On the opposite side of the wheel to the nipple, push the bead under the bead about 5 cm. Do the same with the rest of the bead. Bicycle bumpers can be bought at almost any bike shop. Tighten the bead closest to you so that the bead of the tire rises above the edge of the rim.
Raise the bead of the tire with the rest of the bead until it slides completely off the rim. Take out the camera. Remove the entire tire from the rim - except for the tightest, most tires can be removed by hand.

3. Pump up the camera.
Inflate the tire and try to locate the air leak by ear. I usually try to find the piercing site with my lips. If you still can't find the hole, then try to pump up the camera again and put it in a bowl of water. Now the puncture site is easy to see by the emerging air bubbles. Be sure to let the camera dry before proceeding to the next step.

4. Prepare the camera.
Choose a patch of the required size. When in doubt, always choose the larger patch of two patches. Before sealing the camera, be sure to use sandpaper to roughen the surface of the camera around the hole. There should not be a single glossy area left. Drop one drop of glue and rub it in a thin layer in a radius of 2 cm around the hole. Wait until the glue dries. Apply a second thin layer of glue in the same way. Once again, let the glue dry - it should become matte, not shiny.

5. Attach the patch.
Pump up the camera a little to get a better view of the puncture site. Remove the foil from the patch and press firmly against the camera. The thin cellophane coating on the patch can be left on. To prevent the camera from sticking to the tire, sprinkle the sealed area with chalk, talcum powder, or road dust.

6. Check the tire inside.
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 littered with hedge thorns, I found about a dozen thorns! By comparing the chamber and the tire, you can find the puncture site. Carefully run your fingertips along the inside of the tire to find the items that caused the puncture and remove them.

7. Install the tire.
After repairing the inner tube and checking the tire for glass, thorns, or other sharp debris, install one bead of the tire onto the rim. Inflate the chamber a little, install it in the rim. Insert the nipple into the hole provided for it. Starting on the side of the rim opposite the valve, use your thumbs to wrap the bead (the part of the tire in direct contact with the rim) over the rim. Go around the entire wheel in the same way, leaving only a small area of the tire uninstalled. Use your thumbs to carefully install the remaining bead section of the tire.

8. Do a final check.
Check that the tube is not pinched between the rim and the tire bead. Inflate the tire until it is still soft but retains its shape. Make sure that the circumferential mark of the tire goes evenly along the entire length of the rim. If not, you'll have to lower the tube a bit and level out any protruding spots so that the bead follows the rim evenly.
Inflate the tire to the recommended pressure and check again that the tire bead sits evenly and the tire does not bulge anywhere on the rim. Finally, check that the tread moves straight when the wheel is rotated. If not, then you need to deflate the tire and repeat this step.

Important tips for repairing punctures:

When removing the tube from the tire, remember in which direction the tube was placed in the wheel. This will help to determine the location of the puncture in the chamber, after the location in the tire of the object that caused the puncture has been found.
Use a ballpoint pen to mark the puncture site with a cross so that you know it exactly.
If you don't have sandpaper, you can use stone and pavement instead.
To prevent the beads of easily inflated tires from falling into the rim groove on one side and not swelling on the opposite side, install a thicker rim tape or two rim tapes.
To make tight tires easier to remove and put on, install the rim tape as thin as possible.
Carefully adhere to the puncture repair technique. The last thing you need to install on the rim is a section of the tire at the point of attachment of the nipple. Make sure the tire beads are as deep as possible into the rim groove. When installing some hard tires, beading is indispensable. Use special flanges VAR 425 to help with installation.

Determination of the type of puncture.

Two adjacent small holes in the chamber indicate snake bite, which occurs due to the clamping of the camera between the tire and the rim when driving over a sharp object. Also, these punctures are often facilitated by underinflating the tire to the recommended pressure. Make sure the sidewall of the tire is intact. Otherwise, you can not do without.

A hole on the inside of the camera indicates that the head is to blame for the puncture knitting needles. Check the entire length of the rim to make sure that the spoke holes are covered with rim tape and that 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 a puncture is rough edge of the nipple hole. This puncture is located at the base of the nipple and it is not possible to seal the bicycle chamber.

Create your owncamera repair kit:

Several patches;
rubber glue;
A pair of plastic ribs;
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 ;
LED keychain (useful when);
A pair of spare tires (always carry with you).

Everything except the pump must be packed in a saddle bag.

Systematic tire inspection.

Check weekly for tread cuts, sidewall bulges and wear. Tires with cuts, bulges and tires with sheathing translucent through the tread are not subject to further use. Remove any stones and glass embedded in the tread. Use a pressure gauge to check the tire pressure. Tires that are inflated to the recommended pressure are less likely to puncture and last longer. The recommended pressure is usually indicated on the sidewall of the tire.

Carry spare tubes and tires with you.

In the rain, it is very difficult to seal a bike inner tube, as the patch will not be able to adhere to the inner 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 from the rim or a puncture at the nipple attachment point.

Urgent bicycle tire repair.

Bend in half a large piece of durable polyethylene. Cut the piece to a size that is 10 cm wider than the cut and 5 cm wider than the tire. Remove the tire from the rim. Position the double layer of patch in the center of the gap or cut inside the skin. While holding onto the emergency patch that should protrude from both sides of the tire, install the first bead of the tire onto the rim.

If required, install a new camera and pump it up a little. Install the second bead of the tire, and install the sealed section of the tire last. Make sure the patch is on both sides. Inflate the tire and cut off any excess pieces of the patch, which should be held in place nicely by the tire's air pressure.

You have two options. Go to the service and pay a lot of money or do everything yourself. If you choose to do it yourself, then there are also two options: buy a bicycle first-aid kit or repair the camera from improvised means.

I recommend from improvised means, as it will cost less. However, we should not forget that it is better to buy a bicycle camera repair kit for a long hike or a trip.

If someone does not know how to find the puncture site on the camera, then a basin of water is best. We pump up the camera, immerse it in a basin of water and begin to rotate the camera in a circle. Bubbles will come out of the hole. We notice the puncture site (you can stick electrical tape in this place) and dry the camera. After that, it is ready for repair.

To repair a bicycle inner tube with our own hands, we will need: glue, sandpaper, a piece of an old bicycle inner tube, acetone or gasoline, scissors.

I personally use this method and it works very well. In winter, in preparation for the new cycling season, I sealed all the tubes that needed repair in this way. Now I'm driving and there is no hint that the wheel is lowering or something else. Glued tires behave like new.

Glue. Take glue, the one that I will tell you. This is Super Moment Gel. This one is exactly like in the photo. It is sold in "Magnets". Velohack: in large "Magnets" this glue is cheaper. It cost me 50 rubles, a tube. There are other good bicycle adhesives, but they are almost impossible to find now.

I tried instant adhesives, I tried rubber ones (marathon), but I have not yet met better than "Super Moment Gel". What was glued with instant adhesives fell off, "Marathon" is good for shoes, but it does not hold a patch on a bicycle tube; everything falls off in a week.

"Super Moment Gel" glues so that it has skated for almost the entire season and everything is ok.

How to seal a bike inner tube?

We cut out blanks from a piece of an old bicycle chamber, as in the photo. This is not difficult. The size is not very large, choose empirically. Before cutting blanks, you can clean these places with sandpaper. It's not hard to find an old bike tube.

Either highlight one of your torn ones that any cyclist has, or go to the nearest bike service and just ask. They'll just give it to you for free.

Next, we clean the patch with sandpaper (if not done yet) from the side with which it will be glued to the puncture site on the camera. We also clean the puncture site itself on the camera. We clean well, we capture more space. This gives us a guarantee that the patch will not fall off in a day.

After that, degrease the place of stripping on the patch and on the camera with a cotton swab. We are waiting for it to dry. The adhesive surface must be dry and clean.

Apply some glue to the patch. Next, you can rub the glue on the patch with the tip of the tube until a thin layer is formed, or you can put the patch on the puncture site and move it back and forth a little.

The adhesive will disperse under the patch and protrude along the edges of the patch. Everything is fine, you can glue. We press the place of gluing, as it is written in the instructions for the glue. I usually do this not with my hands, but I take a wooden block and press its surface onto the patch with force. This results in a stronger and more even grip. Everything is ready.

After that, we look to ensure that the patch adjoins the camera evenly and that there are no unglued edges. If they are, then you need to add glue with the tip of the tube and press it. If there are places left unglued at the edges, then the repair will be considered incomplete, and the camera may begin to quickly descend.

After repairing the camera, you can, everything will be ok.

I have never had to glue the camera, I thought it would also stick well with a simple moment. I'm going to do it on a Katyukhin's bike, they lower both chambers, they are already 6 years old. I can buy and replace right away, maybe the spool no longer holds there. How to disassemble the camera? those. take it out and refill it so as not to damage it. Do you have an article ready?

@Vladimir, hello. You know, I didn’t try it for a moment, maybe it will stick. Super Gel keeps the moment with a bang. To check the spool or elsewhere, try slobbering the spool and if it starts bubbling, then it's in it. And if not, then you need to repair the camera. How to board the camera? I don't have pictures for this topic. But it’s not difficult at all: you have to pry it off to pull it out of the rim. Maybe with a key. In general, there is a special assembly for this. I generally do it by hand. Watch with a crowbar and a key so as not to damage the camera. It's easy to set up too. Be sure to inflate the bladder slightly before boarding, because an uninflated bladder may not fit properly. Spread the chamber under the tire and slowly pull the tire itself, holding it with your hands in the right places. There will come a time when you just need to make a little effort to get the tire into place.
