Fork
Ride over obstacles with the hydraulic fork. Its 100 mm travel allows you to calmly overcome more obstacles (roots, pebbles, stones, mud). Its built-in lockout system helps to prevent bobbing and loss of speed on faster terrain.

Rear shock
This mountain bike has no rear suspension. This is a "semi-rigid" mountain bike. Compared to a full suspension mountain bike (with rear suspension), the advantages are clear: this mountain bike is lighter; less energy is lost on flatter ground. If however your primary concern is comfort and manoeuvrability, the ST 540 is available in a full suspension version with suspension at the rear.

No matter what conditions you ride in (dry/wet), the Rockrider by Tektro 160mm double hydraulic disc brakes will come through for you, even in the mud. Hydraulic braking adds more power and progressive braking and requires less powerful use of the brake levers. The aluminium brake levers are easy to grip and precise.
The aluminium wheels are effective and sturdy: 27.5" diameter and double-walled rims. Their diameter is the perfect balance of comfort and performance. With their 28 spokes, they are lightweight, stiff, and durable. The wide, ROCKRIDER ALL CONDITIONS (60 TPI) 27.5" x 2.1 tyres have side knobs designed for riding on all types of terrain (dry, wet, etc.). Tubeless Ready 23 mm rims: SCHRADER valves, TUBELESS rim tape, TUBELESS tyres, and puncture-proof liquid to be added.

Our teams designed and created an exclusive ROCKRIDER ERGOFIT saddle. Designed for all hip widths, its hammock shape is very comfortable for long, athletic rides. The Flex 27.2mm diameter aluminium seatpost also contributes to its increased level of comfort. Quick and easy tool-free adjustment of your saddle height using the adjustment lever on the seat post clamp.

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.
