How to choose an inner tube:

To take good care of your bike, it's important to know the exact dimensions of your tyres.This information is given on the tyre sidewall (diameter and cross-section). For example, 20 x 2.10 means that the tyre is 20 inches in diameter and 2.10 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-406 means a tyre that is 50mm wide and has an inner diameter of 406mm (approx. 20 x 2.00).

Tip from the pros
