How to change an inner tube:
Watch our tutorial.Pump the inner tube up slightly to avoid errors.Place the valve in position, install the inner tube inside the tyre, and push it into the rim without getting the membrane stuck.
Pro advice:
To forestall the risk of puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tyre before each ride.

Inflating a tyre:
Before pumping, check the pressure in PSI or bars.While you\'re pumping, make sure the tyre stays properly in position.
Choosing an inner tube:
To take proper care of your bike, it\'s important to know the exact dimensions of your tyres.This info appears on the sidewall of the tyre (diameter and 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. 29x1.90).
To take the inner tube out, you\'ll need the following tools:
It\'s easy to take your inner tube out using our B\'TWIN tyre lever.
Fitting a tyre:
The right way to mount a tyre is to start with the valve and end on the opposite side, without using a tyre lever to prevent the risk of puncture.
Checks to carry out before installing an inner tube:
For correct mounting, it\'s always good to check everything first: clean tyre, no fractures on the rim strip, no damage on the rim.
