Say hello to XTR Trail brakes, and say goodbye to compromise. The integration of Servo-Wave brake-boosting technology into an XTR-level brake generates gobs of lightweight stopping power (125 percent of the previous XTR benchmark, to be exact) that can be precisely rolled on and off with single-finger effort—leaving a better grip on the bar for charging through the gnarr. With industry-first full ceramic caliper pistons and radiator-fin-backed brake pads to shed performance-sapping heat, these all-new brakes maintain cool, quiet performance under fire. Rotor not included.
