This inner tube allows you to continue cycling when a conventional inner tube would have gone flat.
How to choose your inner tube
Check all the information indicated on the sidewall of the tyre (diameter and width). For example, 29x1.90 means that the tyre is 29 inches in diameter and 1.90 inches wide.On the tyre sidewall you will also find the dimensions in mm in ETRTO international units.For example, 50-622 means that the tyre is 50mm wide with a 622mm internal diameter (approx. 29x1.90).
Removing an inner tube
Remove the old inner tube using a DECATHLON tyre lever.
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

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 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.
