Fork
The hydraulic fork, with 120 mm travel, allows you to easily ride over more obstacles (roots, pebbles, stones, mud). Steer a precise path with the higher diameter dampers (32 mm). The fork's built-in lockout system helps to prevent bobbing and loss of speed on faster terrain.

Brakes

Brakes
No matter what conditions you ride in (dry/wet), the dual hydraulic disc brakes at the front and back will come through for you, even in the mud. Hydraulic brakes deliver more powerful and progressive braking and require less effort applied to the brake levers. The aluminium brake levers are easy to grip and precise.

Understanding sizes and measurements
Height ranges are reported by the manufacturer. A matching range is a starting point, not a guarantee of fit. Your proportions and bike setup also matter.
Reach is the horizontal distance from the bottom bracket to the top of the head tube; stack is the vertical distance.
Positive values mean more reach or stack than the reference size; zero means the same measurement. Missing values are not estimated.
Enter your height to highlight matching ranges.
