It will start with one of the recurring nightmares for every cyclist: the so-called “punctured rubber”.

Bicycle puncture repair

A hole, a piece of glass or other sharp materials on the road can be among the causes of a puncture. The obvious sign of what happened is clearly the reduced pressure of the tire, an indication which, however, can also signal a partial or even total opening of the valve. It is therefore necessary, first of all, to make sure that there is a puncture. First turn the bike over and remove the wheel and then the inner tube, if necessary after loosening the brakes. If completely deflated it will be filled with a minimum quantity of air in order to identify any possible tearing. You can proceed by placing your ear close to the tube to identify with your hearing the leaks or fill with a little water a large basin and not very high: the bubbles created in the liquid will indicate the drilling. In any case, check the entire surface to exclude further damage. The advice is to bring a do-it-yourself tire repair kit whenever possible, especially if traveling.

Alternatively, you can prepare one for yourself, taking care to include: a tire-removal lever, in plastic or metal; some patches, which can be made with cut-outs of non-repairable air chambers; mastic; some scraps of fine sandpaper; latex gloves to avoid getting your hands dirty or come into direct contact with the adhesive; a spare inner tube, in the event that the damage is not repairable (for example, if the cover has a large number of holes or if it has extensive cuts). Completely deflate the inner tube and lightly pass the sandpaper on the surface around the hole to be repaired. At this point distribute the glue in an area equal to that of the patch, proceeding in a similar manner before resting it. Apply the patch to the drilling area and hold for 5-10 minutes, preferably with a weight that can guarantee a constant pressure and eliminate any possible air bubble. Any excess mastic must be removed, as well as the protective transparent sheets present on some types of patches Read more
