Description

This inner tube allows you to continue cycling when a conventional inner tube would have gone flat.

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.

How to change an inner tube

Before installing your inner tube, watch our video, inflate it slightly, insert the valve, fit it properly into the tyre and then into the rim.

Inflating a tyre:

Before inflating, mark the recommended values on the tyre sidewall.All the while, make sure it's properly positioned.

Choosing an inner tube:

To maintain your bike properly, it's important to know the exact dimensions of your tyres.This information appears on the tyre sidewall (diameter and width).For example, 20 x 2.00 means your tyre is 20 inches in diameter and 2.00 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-406 means that the tyre is 50 mm wide and has an inside diameter of 406 mm (i.e. 20 x 2.00).

Pro advice:

Tyre pressure must be adjusted before each outing to avoid punctures caused by pinching.

Checks to make before installing an inner tube:

To avoid repeated punctures, carefully inspect the tyre, rim tape and rim each time you change.
