Shimano Disc brake GRX Di2 ST-RX815/BR-RX810, rear, FM (Flat-Mount)

Instead of dictating to gravel bikers what they should use for their tours, Shimano considered what cyclists need for their adventures off paved roads. The result is the Shimano GRX components, which together form the first group specifically developed for use on rough tracks and gravel. The Shimano GRX stands out from the rest of the component world with its gravel-specific ergonomics, optimized gear options, proven robustness, and a quiet and stable drive.
