Shimano XTR M9100 Hydraulic Disc Brake

Shimano's XTR M9100 is the flagship hydraulic disc brake for cross-country and enduro mountain bikes. Its 4-piston caliper with Servo Wave lever action provides progressive modulation from the first finger contact through to full lock, and the IceTech metallic pads dissipate heat across the rotor's finned aluminium core. Trek, Specialized, Scott, Orbea, Santa Cruz, Cannondale, and BMC all specify XTR M9100 on their S-Works and top-specification trail builds.
