SRAM S-900 Aero HRD Flat Mount Rear Disc Brake

Introducing the SRAM S-900 Aero HRD, unconditional braking for time trial (TT) and triathlon riders who are looking to improve their performance.

For aero disciplines, hydraulic disc brakes can reveal a whole new world of speed savings. Cut precious seconds by spending less time slowing down. More powerful brakes mean faster splits, thanks to confidence-inspiring brake performance. Disc brakes enable aerodynamic optimization of the most important leading edge of the bike frame - the fork crown/head tube/down tube. Hydraulic road disc brakes (HRD) also require less hand effort to actuate and provide shorter braking distances and easier changes between wheelsets.

Reach AdjustT
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.
Bleeding EdgeT
This 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.
Stealth-a-majigT
This 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.
