High end Dual-Pivot Caliper front brake ULTEGRA BR-R8000 from SHIMANO Stabilizer between axles reduces deformation and improves braking efficiency More predictable, linear braking curve Narrower gap between arms Compatible with wider 28C tire size Clear contact feeling with balanced rigidity, weight and stopping power Sleek design Wider clearance with larger tire sizes Weight: 182 g SLR-EV is SLR with a dual symmetric pivot brake caliper. The short-arm brake design employs two bearings and a roller to realize greater efficiency in the pivot area and deliver superior modulation and power for braking. Together with the BC-9000 brake cable, the latest calipers deliver 36% more braking power than SHIMANO’s previous brake model.
