The professional\'s advice

Inflate your tyres before every ride to reduce the risk of punctures and ride more efficiently.

Checks to carry out before installing an inner tube:

Make sure that the rim tape covers all the spoke holes. A cracked or misaligned rim tape can damage the inner tube. The rim tape must be centred, clean and in good condition. Replace the rim tape if it is cracked, stiff or worn. New rim tape effectively protects your inner tube from pinching. Use rim tape that is suitable for the width and diameter of your rim. Good rim tape prevents internal punctures caused by the spoke heads.

How to change an inner tube:

Follow our video guide before you start.A slight amount of air pressure in the inner tube will prevent pinching.Insert the valve, position the inner tube correctly in the tyre and then in the rim.

To remove your inner tube, you will need the following tools:

An essential tool for removing an inner tube:B’TWIN tyre levers.

Inflating a tyre:

The ideal pressure is indicated on the sidewall of the tyreInflate carefully and check that the tyre remains correctly positioned.

Fitting a tyre:

Start at the valve and work your way to the opposite side.Do not tighten with a tyre lever to avoid the risk of punctures.

How to choose an inner tube:

To maintain your bike properly, it\'s important to know the exact dimensions of your tyres.This information can be found on the sidewall of the tyre (diameter and section). For example, 20 x 1.60 means a tyre with a diameter of 20 inches and a width of 1.60 inches. On the sidewall, you will also find the dimensions in mm in the international ETRTO unit. For example, 40-406 means a tyre that is 40 mm wide and has an inner diameter of 406 mm (i.e. 20 x 1.60).
