    Fork

    Take on new challenging terrain (roots, stones, gravel, etc.) with ease thanks to the travel of the front suspension fork.

    Groupset
    Crank

    The new chainset has a 140 mm crank that is designed for a child's leg length. This chainset allows you to start pedalling more easily. The crank is covered to prevent the child from coming into contact with the metal part. The double chain guard prevents the chain from derailing.

    Tires

    The tyres are designed for mountain biking. The lateral lugs provide good grip on turns. The tyres use SkinWall technology. This process reduces their weight and makes them more flexible, which increases performance, grip and comfort. The recommended tyre pressure is indicated on the side of the tyre (2 to 3.5 bars). 20" inner tube, 1.7" to 2.2" Schrader valve.
