Shimano GRX ST-RX810/BR-RX810 Shifter/Hydraulic Brake Lever Set

The Shimano GRX ST-RX810/BR-RX810 Shifter/Hydraulic Brake Lever Set pairs an 11-speed mechanical shift lever with a hydraulic disc brake caliper built specifically for gravel riding — sold as a single side, so you can spec front or rear independently. The shift lever features anti-slip textured grips designed to keep your hands secure on rough, unpredictable terrain, while the hydraulic caliper delivers modulated stopping power across all surfaces with flat-mount compatibility.

The BR-RX810 caliper is built with anti-mud properties to resist clogging in off-road conditions, and the system is designed for straightforward maintenance — tool access, wheel removal, and bleeding are all laid out with minimal hassle in mind. At 284g (left) or 286g (right) for the lever and 140g for the caliper, the pairing keeps weight in check without compromising the control and confidence you need when the road turns to gravel.

Note: This product includes one shifter, brake caliper, and hose — front/left or rear/right. Select your variant above.
