    Choosing an inner tube:

    To take good care of your bike, it's important to know the exact dimensions of your tyres.This info appears on the tyre sidewall (diameter and section).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 50 mm wide with an inner diameter of 584 mm (27.5 x 2.00).

    Here are the tools you'll need to change your inner tube:

    Remove the old inner tube using B'Twin tyre levers

    Checks to make before installing an inner tube:

    Before installing an inner tube, always carry out a complete check of the tyre.

    How to change an inner tube:

    To avoid making mistakes, watch the step-by-step video.Slightly pre-inflate the inner tube, place the valve in its hole, install the inner tube, push it into the rim, without pinching.

    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:

    Adhere to the pressure shown on the sidewall.Make sure the tyre settles into place evenly as you pump.

    Pro advice:

    Keep your tyres in mind:check their pressure before each ride to prevent any problems.
