All-new forged aluminum calipers and lever bodies deliver robust power at a fraction of the weight, while tool-free contact point adjustment puts you just a few clicks away from your perfect ride.

The SRAM XX Disc Brake uses an all-new, two-piece forged magnesium caliper for greater stiffness and performance in a lighter-weight package. Oversized pistons give you more stopping power with less lever pull for easy one-finger braking. An updated TaperBore design incorporates a new air-trap feature, which prevents potentially trapped air from entering the system, resulting in ridiculously smooth control you can count on. Super light XX carbon fiber lever blade, two-piece rotor construction, titanium hardware, pad contact and reach adjustments. Front and rear sold separately.
