TECHNICAL INFORMATIONS

How to choose your inner tube

Check the information indicated on the sidewall of the tyre (diameter and width). For example, 27.5 x 1.90 means a tyre with a 27.5-inch diameter that is 1.90 inches wide.
On the tyre sidewall you will also find the dimensions in mm in ETRTO international units.
For example, 50-584 means your tyre is 50mm wide with an inner diameter of 584 mm (27.5 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

Mounting the 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 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 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 avoid punctures from pinching and for the best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.
