As its name implies, this is SRAM's Ultimate brake design for cross-country and light trail use. They took the same technology used in the brake that Loic Bruni rode to a Downhill World Championship and packed it into smaller, sleeker, lighter-weight and XC-optimized package. The carbon-fiber lever blade pulls crisp and clean thanks to pivot bearings and SRAM's DirectLink design. And it maintains that feel throughout the ride because it is matched to their monoblock, two-piston caliper. This caliper’s superior heat management and smooth piston actuation give you braking power exactly when and how you need it. And the BLEEDING EDGE design significantly simplifies fluid maintenance.
