The SRAM Rival Aero disc brake brings genuine hydraulic power and control to TT and triathlon, built around the same aero-conscious construction as the rest of SRAM's Aero line. A carbon lever and tooled reach adjust deliver a precise, deliberate fit, while a 2-piece forged aluminum caliper with titanium hardware provides real stopping power under race conditions. What Our Gearhead(R) Experts Are Saying:"I've pulled this brake hard out of the aero bars into a technical turn, and the modulation stays controlled the whole way through the stop. That kind of precision at speed is exactly what a TT setup needs from its brakes."
