Its 680 mm width guarantees good stability and optimal comfort when steering.

With a 29.8 mm diameter and 350mm length (S frame size and 400mm in M and L frame size), the B'Twin Comp seat post offers a wide range of adjustments and a raised riding position.
Double hydraulic disc brakes: incisive braking
The exclusive 180mm (front) and 160 mm (rear) TEKTRO TKD 32 double hydraulic disc brakes will stop you in all circumstances. With their 2 pistons, semi-organic pads, and aluminum body, they combine power and lightweight, essential for cross country riding. For even more efficiency, the brake levers have been specially designed to be quickly manipulated with 2 fingers.
