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.

Technology

Bleeding Edge
The Bleeding Edge Technology allows quick and easy bleeding of the brakes. Thanks to the fluid channel and the specially designed bleed vent, the fluid can be pumped through the calliper more easily. A special adapter can be fitted to the bleed port and seals the system to prevent air ingress and fluid loss.

Stealth-a-majig
With Stealth-a-majig, installing the hydraulic hose during assembly is child’s play. Its smaller size allows for easy cable routing, which gives the bike a tidy look.
