Aerodynamically shaped and featuring a dual-pivot design, the Shimano Ultegra R8000 Brake Caliper will enhance the looks and braking performance of any road bike. It's responsive, powerful and reliable in all weather conditions. The wider clearance of the Shimano Ultegra R8000 brake makes it compatible with larger tyre sizes such as 700x28C. The stabilizer between the axles reduces deformation and improves the braking efficiency, offering a clear contact feeling with balanced rigidity, weight and stopping power.
