This inner tube is compatible with 26" diameter tyres, with a cross-section ranging from 1.20 to 1.50 with a 48 mm Presta valve.

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, 26x1.40 means that the tyre is 26 inches in diameter and 1.40 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 38-559 means that the tyre is 38 mm wide with a 559 mm internal diameter (approx. 26x1.50).

To remove your inner tube, the tools you'll need are:

Remove the old inner tube using B'Twin tyre levers

Checks to make before installing an inner tube:

Check the condition of your tyre and replace it if necessary. Make sure there are no foreign bodies 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:

Follow the steps in our video:A small amount of air pressure, a well inserted valve, a well fitted inner tube, and no tension or pinching in the rim.

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:

Follow the pressure recommendations shown on the sidewall.Check the alignment of the tyre regularly during inflation.

Pro advice:

Check and re-inflate your tyres if necessary before each ride to avoid pinching.
