SRAM Red Rear Rim Brake Caliper B2: Security at your fingertips with a fresh look to compliment SRAM RED eTap componentry. SRAM RED brakes wonÕt slow you down. Until youÕre ready. ThatÕs why the SRAM RED brakeset has been created with a host of wind cheating features to make the brake body more aerodynamic, helping you keep your speed until the moment you're ready. The patented AeroLink arm reduces frontal area while improving braking performance and modulation. The brake body, with updated graphics, has been sculpted to provide a sleek aerodynamic profile to the wind. Even the smallest details, like the barrel adjuster, point away from the wind. And to finish off the package, SwissStop Flash Pro pads come standard with the brake. ItÕs a better brake in every way.
