SRAM S-900 Aero HRD Disc Brake

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.
