Recommended caliperBR-S7000
Hydraulic disc brakes can provide strong, controllable braking, especially in rain and descents. Rim brakes require a suitable frame and braking surface. For loads and long descents, consider the complete brake, rotor, mounting and heat-management combination.
Gear range307%
A wider gear range can combine climbing or carrying loads with speed on flats. Range percentage does not specify gear steps or the absolute lowest gear. Compare chainring and cassette or hub ratios as well.
ColorsBlack, Silver
Colour and origin are mainly personal preferences; they do not automatically make a part faster or more suitable. Choose the finish matching your bike and maintenance preferences after checking fit and function.
