A frame designed to combine fun and performance
For the XC100, our teams have specifically designed the frame in T4 & T6 6061 aluminium (only 1.8kg in size M).

Handlebar, stem, grips: keep control
Since cross country requires good control of your steering position, we equipped this mountain bike with an oversize low rise Rockrider XC100 Series handlebar (slightly curved). Its 680 mm width guarantees good stability and optimal comfort when steering. The ROCKRIDER XC stem is adapted to each size (80mm in size M, 90mm in size L) Semi-integrated headset with sealed bearings. ROCKRIDER 900 light lock on grips.

For even more efficiency, the brake levers have been specially designed to be quickly manipulated with 2 fingers.
