The Shimano Ultegra BR-R8010-R is a rear direct-mount caliper brake designed for road bikes with compatible frame mounts. It uses Shimano’s SLR-EV dual-pivot mechanism to provide consistent, responsive braking performance. The caliper supports wider tires up to 28 mm and includes Shimano R55C4 brake shoes, which are optimized for aluminum braking surfaces. Its compact, aerodynamic design integrates cleanly into the rear triangle or under the bottom bracket, depending on frame layout.
