  • Liquid inside makes it self repairing - clever eh?
  • Water won't get in

Technical Information

How to choose your inner tube

Check the information indicated on the sidewall of the tyre (diameter and width). For example, 26 x 2.00 means your tyre is 26 inches in diameter and 2.00 inches in width.
On the sidewall, you will also find the dimensions in mm in international ETRTO measurements.
For example 50-559 means the tyre is 50 mm wide with an inner diameter of 559 mm (or 26 x 2.00).

Removing an inner tube

Remove the old inner tube using B'Twin tyre levers.

Checks to carry out before installing an inner tube

Check the condition of your tyre and replace it if necessary.
Make sure no objects are lodged 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.

Fitting your 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.

Mounting the tyre

Start by mounting the tyre onto the wheel on the opposite side to the valve.
Finish mounting it on the valve side to avoid pinching it
Never mount your tyre with a screwdriver or a tyre lever, as you risk pinching and puncturing the inner tube.

Inflating the 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.

Tip from the pros

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.
