SHIMANO GRX 前碟式煞車組-ST-RX810

Shimano asked gravel riders what they wanted from their off-road experiences rather than telling them what they needed. The end product is the Shimano GRX components, which are the first series specifically designed for riding through gravel and on rough roads. With its optimized gearing options, rugged dependability, quiet and stable drivetrain, and gravel-specific ergonomics, the Shimano GRX distinguishes itself from the rest of the component industry.

The ST-RX810 STI lever with SERVOWAVE technology and the hydraulic BR-RX810 calliper with ceramic pistons for superior braking performance make up the Shimano GRX shift/brake set.
