For aero disciplines, hydraulic disc brakes can reveal a whole new world of speed savings.

Less time slowing down means more time going fast. Better brakes mean faster splits, thanks to confidence-inspiring brake performance. Hydraulic aero brakes also allow for more aerodynamic frame designs, lower hand effort, shorter braking distances, and easier changes between wheelsets. SRAM Aero HRD is unconditional braking for unconditional riders.

Technologies

Bleeding Edge - Bleeding Edge technology makes bleeding brakes quick and simple. An updated fluid path and bleed porting make it easier to push fluid through the caliper. A dedicated bleed adapter plugs into the bleed port and seals the system to minimize air contamination and fluid loss.

Reach Adjust - Brake lever fit and feel is a personal thing. Riders have individual positioning preferences, as well as unique hand sizes and finger lengths. Reach Adjust makes it easy to adjust your lever for maximum one-finger control for everyone.

Stealth-a-majig - Stealth-a-majig is the coupling that makes initial setup of hydraulic systems fast and convenient. Its smaller size allows for easier internal cable routing, giving bikes a clean look.
