    Fork

    The 80 mm front suspension helps you overcome your first obstacles on slightly uneven trails with no worries. Its mechanical spring is a stamp of reliability. And the fork is particularly easy to maintain. To adjust the stiffness? It's very easy using a single dial.

    Saddle

    The saddle of the ST 100 is welded to prevent any movement of the saddle. And because your comfort is our next priority after safety, we've added an exclusive wider Ergofit saddle with a hammock shape. Easily adjust the height of your saddle with the Flex steel seat post, either 350mm or 400mm long (according to the bike size). Its reduced diameter of 27.2mm provides your seat with natural flexibility, 30% more than a standard solution.

    Brakes

    Two V-Brake pads for effective braking. These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels. Thanks to the special design of the ST 100's aluminium brake levers, you only need two fingers to brake.

    Wheels
    Tires

    The wheels of the ST 100 are tolerant and robust, with 27.5" double-walled 28-spoke rims (26" for the XS size). Slow down without worrying about obstacles: small rocks, cracks, holes and bumps! Because your first rides will be on dry ground, this mountain bike is equipped with DRY 27.5 x 2.0 tyres. Their performance has been optimised thanks to a faster central section, while their side lugs offer excellent traction in turns.
