Choosing an inner tube:
To choose the right inner tube for your bike, it is essential to know the exact dimensions of the tyres.This information is indicated on the sidewall:diameter and width.
For example, 700x35 corresponds to a tyre with a diameter of 700 mm and a width of 35 mm.
The ETRTO designation(e.g. 35-622) also specifies the width (35 mm) and inner diameter (622 mm), which is equivalent to 700x35.
Removing an inner tube:
Use B’TWIN tyre levers to remove your used inner tube.
Checks to make before installing an inner tube:
Check the condition of your tyre and replace it if necessary. Ensure that there are no foreign objects in the tyre.
Check the condition of your tyre rim strip.
A rim strip that is even slightly bent can cause punctures.
Check that your rim does not have any other issues that could damage your inner tube.
How to change an inner tube:
Watch our video before you start.
Pre-inflate the inner tube slightly to avoid pinching.
Insert the valve, making sure you are using the correct valve for your rim.
Put the inner tube entirely inside the tyre so that it fits inside the rim.
Take care not to pinch the inner tube when fitting.
Fitting a tyre:
Start mounting the tyre at the valve.
Finish mounting the tyre opposite the valve to avoid pinching the inner tube.
Never mount your tyre with a tool or a tyre lever, as you risk pinching and puncturing the inner tube.
Inflating a tyre:
Inflate your tyre carefully, to the pressure recommended by the manufacturer (visible on the tyre sidewall in PSI or bars, 1 bar = 14.51 PSI).
Regularly check that your tyre is in the correct position as you inflate it.
Pro advice:
To prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tyre before each ride.
