Magura Race Pro Hydraulic Disc Brake Set Four Pistons. Cross-Country Weight. Riders who want 4-piston braking on a race build usually trade weight for power. The Race Pro skips that trade. Built entirely from forged and CNC-machined aluminum, it's Magura's most powerful brake yet at 310 grams per brake. A radial master piston and ball-bearing lever pivot cut friction out of the system so nothing gets lost between your fingers and the rotor.
