Shimano Dura-Ace R9270 Disc Brake Caliper Front
With a one-piece body, the front Shimano Dura-Ace R9270 Disc Brake Caliper offers exceptional rigidity and braking accuracy while keeping the weight low. Installation is easy thanks to the shimless mounting bracket, and quick wheel swaps are facilitated by the direct flat-mount design. In addition, rotor compatibility is excellent, allowing either 140mm or 160mm sizes to be used.
Opposing oversized ceramic pistons guarantee braking power and consistency, while a 10% increase in pad spacing minimises the occurrence of brake drag, particularly during long descents. Resin compound pads include integrated fins for quicker heat dissipation, further enhancing control during prolonged braking.
A redesigned bleed port, valve screw and hose routing combine with the one-way internal fluid circuit to make bleeding and maintenance faster and easier, helping professional and home mechanics alike.
