    Pro advice:

    Check your tyre pressure before every ride to avoid pinch flats and ensure optimal performance.

    Choosing an inner tube:

    To properly maintain your bike, it is essential to know the exact dimensions of the tyres, which are indicated on their sidewalls (diameter and width).
    For example, 27.5x2.00 refers to a tyre that is 27.5 inches in diameter and 2.00 inches wide.
    The ETRTO, such as 50-584, indicates a width of 50 mm and an inner diameter of 584 mm, which is equivalent to 27.5x2.00.

    Checks to make before installing an inner tube:

    Inspect the tyres for wearand replace them if necessary. A worn tyre can cause a puncture:check it before each ride.Replace your tyre if it is deformed, cracked or smooth.
    Check the tread and sidewalls.Visually inspect the tyre (cuts, cracks).Change your tyre at the first signs of wear.The lifespan of a tyre varies depending on use.

    How to change an inner tube

    Before you begin, watch our explanatory video.Lightly inflate the inner tube, insert the valve into the valve hole, place the inner tube correctly in the tyre, then into the rim without pinching it.
