The 120 mm Rockshox 30 Silver Air hydraulic fork is 400g lighter than that of the ST 540 mountain bike. It is conical and offers even more stiffness and precision when steering. Easily adjust the fork's bounce and stiffness. Its quick COMBO LOCK lockout system, which you can control from the handlebar, helps prevent bobbing and loss of speed on faster sections.
The single chainring is easy and efficient to use. 1 chainring and 11 speeds: accelerate on the flat and take on climbs with no compromise. 1 single shifter on the handlebar: adapt your speed instantly like the pros as the terrain changes! In detail:, -SRAM X1000 32-tooth single chainring, -MICROSHIFT M665 11-speed rear derailleur, -MICROSHIFT M8515 right shifter, -MICROSHIFT H113 11-cog 11 to 46 teeth cassette, -KMC X11 chain
No matter what conditions you ride in (dry/wet), the Rockrider by Tektro 180 mm (front) and 160 mm (back) double hydraulic disc brakes will come through for you, even in the mud. Hydraulic braking adds more power and progressive braking and requires less effort applied to the brake levers. The aluminium brake levers are easy to grip, lightweight, and precise.
Our teams designed and created an exclusive ROCKRIDER ERGOFIT Pro saddle. Designed for all hip widths, its hammock shape is very comfortable for long, athletic rides. The aluminium Rockrider Sport seat post is lightweight and has a wide adjustment range, with a 31.6 mm diameter and 400 mm in length. Quick and easy tool-free adjustment of your saddle height using the adjustment lever on the seat post clamp.
