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 2.20 means a tyre with a 26 inch diameter and 2.2 inches wide.
On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-559 means a tyre that is 50 mm wide and has an inner diameter of 559 mm (approx. 26 x 2.00).

Removing an inner tube

Remove the used inner tube using B'Twin tyre levers (item code 8047839).

What to check before installing your new 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 issues that could damage your inner tube.

Fitting your inner tube

Pre-inflate the inner tube slightly to keep it from getting pinched.
Insert the valve, making sure you are using the correct valve for your rims.
Put the inner tube entirely inside the tyre so that it fits inside the trough of the rim.
Take care not to pinch the inner tube when mounting the tyre onto the rim.

Mounting the tyre

Start by mounting the tyre onto the wheel on the opposite side to the valve.
Finish mounting the tyre at the valve to avoid pinching the inner tube.
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 sidewall of the tyre in PSI or bars; 1 bars = 14.51 PSI).
Regularly check that your tyre is in the correct position as you inflate it.

Tip from the pros

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