SHIMANO Grx Br-Rx810 Flat Mount Disc Brake Caliper Black, Left/Front

Our all-road adventures have us taking on technical single track, gravel logging roads, and even the occasional stretch on blacktop to link it all together, so we need brakes that can handle it all. Utilizing Shimano's time-tested 2-piston hydraulic caliper design, the Shimano GRX BR-RX810 Flat Mount Disc Brake Caliper gives us unreal braking control and power so we can tackle mixed terrain with confidence. Fins on the Ice Tech brake pads dissipate heat, so we don't get into sketchy situations on technical descents, while the one-way bleeding feature makes bleeding our brakes a quick and easy job.
