During your bicycle ride you carry a spare inner tube, but it just accidentally happened that you already punctured even your second inner tube? Probably you will keep the punctured inner tube because you don’t want to throw it, but as well you will keep it in reserve for the next case of puncturing…

How to patch and preserve the inner tube, and to save ourselves from pushing up to the first bicycle store for help?

Short photo strip that will assist you:

1. Remove the wheel from the bike by releasing the shutter wheel. If it comes to the rear wheel, put the transmission on the smallest sprocket to make it easier to remove the wheel, and later it is easier to return it to the bike.


2. Use at least two plastic installers to remove one edge of the tire from the rim.


3. Manually pull the inner tube out of the tire to be able to find a hole on the inner tube. The easiest way to find the hole will be if you pump the inner tube completely full, and you will be able to hear where the air goes out.


4. After that, try to pass through a tire with your hands trying to feel for the rest of sharp objects if left. If you don’t do it, punctured inner tube will be broken again. Do it slowly so you don’t hurt yourself on a piece of glass, wire, thorn or something else that might caused the puncture of inner tube.


5. Found hole clean with tin scraper from the puncture repair kit.


6. Apply a thin solvent for rubber from the tube and spread it with your finger over the hole and the surrounding areas, so that the coated surface is much larger than the patch.


7. Remove the protective film from the patch, while not touching the surface of the patches you need to stick to the inner tube in order to cover the hole. Do not coat patch solvent!


8. Some minutes after you spread the solvent, strongly press the patch over the hole on the inner tube.


9. To enable the patch takes the elasticity of inner tube, remove the protective film from it. This is also a test of firmness of adhesive patches, because the edges of the patches must be fully nestled to the inner tube.

10. Gently inflate the inner tube to acquired basic shape, but remained soft. Such inner tube put in a tire and return it to the edge of the rim, preferably by hand. If you can not use hand, re-use plastic installer.


11. Inflate the inner tube to the recommended pressure and continue driving!
