Bicycle outdoor sports when the inner tube is punctured how to emergency repair?

When riding outdoors, the inner tube is punctured, the most convenient is to directly change the inner tube, to the resting place and then replace the broken tire patch as a spare. Emergency repair and normal repair are the same operation.

The following picture shows the tools needed to repair the inner tube:

Tire Repair Steps:

First, use a tire pry bar to pry open the outer tire and take out the inner tube.

Find the broken eye, use a file to file around the eye (the file should be larger than the range of the tire patch). Rub in one direction as you file.

Then apply the tire patch glue, spreading the glue evenly with the end of the glue or a tire pry bar. The glue should also be applied slightly larger than the tire patch.

Wait for 3-5 minutes depending on the climate, you can lightly press the glue with your fingers, not too sticky.

The time spent waiting for the glue to dry is used to check if there are still sharp objects on the outer tire. Use your fingers (don't wear gloves) to feel the inside of the outer tire, if there is a sharp object, you will feel it in your fingers, find it and pull it out.

Press the patch slowly from one end to the other, press out the air and stick the patch so that the puncture hole is in the center.

Use your hand to push the air out of the patch, also reinforcing the adhesion of the patch.

The tire patch is complete, and the wheelset is mounted.

There is also a kind of glue-free tire patch, that is, omit the step of applying glue in the above steps, and the other items are used in the same way, only the last film used is the glue-free tire patch.

Note: Whether it is a tire repair or a new tire, you must check whether there is still something on the outer tire that can puncture the inner tire. Otherwise the hole will continue to be punctured again.
