Product Details
The Shimano Ultegra BR-R8170 Hydraulic Disc Brake Caliper offers riders and mechanics improved performance with its advanced modulation and quieter braking system. This new caliper provides a more responsive braking feel and a quicker initial bite, enhancing control on the road. Despite its compact design, it operates with less noise and is easier to maintain. The 10% wider pad clearance reduces brake noise, while the user-friendly bleeding process simplifies maintenance.
