Shimano GRX BR-RX810/810 Rear Brake 11s 1700

Instead of telling cyclists what they need, Shimano asked them what they want for their Offroad adventures. The result is the Shimano GRX components, which represent the first series specially designed for riding on uneven roads and through gravel. Shimano GRX stands out from the rest of the component world with gravel-specific ergonomics, optimized gearing options, solid reliability, as well as quiet and steady drive.
