Aero bars create a problem for hydraulic braking: traditional hoods don't fit the position, and running cables defeats the purpose of slippery time trial cockpits. The S900 Aero lever mounts directly to clip-on extensions or base bars, putting hydraulic stopping power where you actually need it during a TT effort. The lever body uses a low-profile design that tucks into the aerodynamic envelope rather than disrupting it.

SRAM pairs the lever with their S900 flat mount caliper, which uses a single-piece monoblock construction machined from aluminum. The caliper accepts standard SRAM and Avid disc brake pads and works with 140mm or 160mm rotors depending on your frame's mounting provisions and braking needs. Hydraulic actuation delivers consistent lever feel regardless of heat buildup during long descents or repeated hard braking.

The system ships as a complete front or rear unit with lever, caliper, and pre-bled hose. You're getting a matched system rather than piecing together components, which eliminates compatibility questions and means the brakes are ready to install without bleeding. Hose length accommodates most TT and triathlon setups, though you may need to shorten for cleaner routing on compact frames.... Read More
