Description

The SHIMANO DURA-ACE Di2 R9270 Right Lever and Rear Caliper completes the DURA-ACE electronic cockpit, with ultra-fast wireless shifting and completely redesigned lever ergonomics. Made from carbon fibre with titanium hardware, it provides light weight and precision, while SERVOWAVE technology refines brake modulation.

The BR-R9270 rear caliper, with a Mono-Body design, combines stiffness and compactness. Its increased pad clearance reduces brake noise, while its One Way Bleeding system with an independent bleed screw simplifies maintenance without removing the frame.

Sold without a rotor, this set ideally complements the left-hand side for a complete performance-focused DURA-ACE Di2 groupset.
