Front suspension
The 80 mm front suspension helps you overcome your first obstacles on slightly uneven trails with no worries.
V-brakes with pads
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. One a year, check how the pads are wearing. If the grooves are disappearing, take your bike to your local store's workshop.
