Description

The SHIMANO DURA-ACE Di2 R9270 Left Lever and Front Caliper embodies the best of Shimano road technology, with ultra-fast wireless shifting and completely redesigned ergonomics. The lever, made from carbon fibre with titanium hardware, offers a refined grip and enhanced control thanks to SERVOWAVE technology, which improves brake modulation.

The BR-R9270 caliper, with its Mono-Body design, stands out for its exceptional light weight and stiffness. Its 10% wider pad clearance reduces braking noise, while the One Way Bleeding system with a separate bleed screw makes maintenance much easier.

Sold without a rotor, this high-end electronic set is designed for the performance and endurance of demanding cyclists.
