TECHNICAL INFORMATIONS
How to choose an inner tube:
To maintain your bike properly, it's important to know the exact dimensions of your tyres.This information can be found on the sidewall of the tyre (diameter and section).

On the sidewall, you will also find the dimensions in mm in the international ETRTO unit.
For example, 40-406 means a tyre that is 40 mm wide and has an inner diameter of 406 mm (i.e. 20 x 1.60).
