Overview
Rear Disc Brake Caliper Shimano GRX BR-RX810 Flat Mount
The Shimano GRX BR-RX810 is a hydraulic 2-piston rear disc brake caliper with Flat Mount design, developed for gravel, road and cyclocross bikes. It delivers powerful and precisely controlled braking performance on both paved and loose surfaces.
Based on Shimano’s road Flat Mount platform, the GRX caliper provides the same high braking performance. ICE TECHNOLOGIES heat management with finned L03A brake pads ensures efficient heat dissipation and consistent braking on long descents. Shimano’s One-Way Bleeding system makes maintenance simple and clean.
The aluminium caliper with ceramic pistons reduces heat transfer to the brake fluid, enhancing reliability in demanding conditions. A straight hose connection and compact design simplify installation and wheel changes.
