TECHNICAL INFORMATIONS
Choosing an inner tube:
To take proper care of your bike, it's important to know the exact dimensions of your tyres.You'll find this information on the tyre sidewall (diameter and cross-section).
For example, 29x1.90 means that the tyre is 29 inches in diameter and 1.90 inches wide.
On the tyre sidewall you will also find the dimensions in mm in ETRTO international units.
For example, 50-622 means that the tyre is 50mm wide with a 622mm internal diameter (approx. 29x2.00).
