Drive train
The XC50 uses a completely new SRAM single-plate transmission system. SRAM SX 1x12 shifting ensures mountain bike resistance, precision and better control. The SX integrated crank pressure plate and DUB bottom bracket ensure efficient and stable pedaling force transmission.
HANDLEBAR / STEM / STEERING / GRIPS
Stability helps you find an attacking position. Rockrider Comp Flat handlebar width is 680 mm, which is in line with Asian shoulder width and increases control stability. The headset system uses press-fit sealed bearings, which is flexible and efficient. -17° 80mm stem provides an attack angle more suitable for XC
SADDLE / SEAT POST
The ROCKRIDER XC/AM cushion weighs 265 grams. The aluminum alloy seat post is height-adjustable. Seat post measures 31.6 x 400.
BRAKES
Customized 180/160 mm TEKTRO TKD 32 dual hydraulic disc brakes are customized and debugged for advanced users. The operation feels smooth and the braking effect is moderate, which can prevent users from causing accidents due to direct lockup in case of sudden danger
