The SRAM RED Brake Caliper Set's braking power and modulation are maximized thanks to the cleverly designed AeroLink arms. Those arms amplify braking power and the aggressive, precision shaping of the caliper body and arms maintain stiffness while REDucing weight and yielding a smaller, more aerodynamic profile. Even minute details, such as the quick-release and barrel adjuster are designed to optimize aerodynamic performance so when you want to go fast, you fly! And wide profile, aero wheels fit perfectly thanks to independent spring tension adjustments and increased wheel and tire clearance. To finish these fantastic brakes, SwissStop Flash Pro brake pads are mounted to SRAM lightweight, aerodynamic pad retainers.
