Shimano GRX BL-RX810/BR-RX810 Left Side Hydraulic Brake Lever/Caliper Info
The Shimano GRX BL-RX810/BR-RX810 Left Side Hydraulic Brake Lever/Caliper is sold as a single-side kit — one lever, one caliper, and hose — designed specifically for mechanically shifting gravel bikes that run 11-speed drivetrains. The lever's ergonomics are shaped for the varied hand positions that gravel riding demands, giving you confident reach whether you're upright on a fire road or tucked in on pavement.
The BR-RX810 caliper is flat-mount and built with anti-mud properties to keep the hydraulic system functioning when conditions turn dirty. Heat dissipation is handled well enough for extended descents, and the bleeding system is straightforward — tool access and wheel removal are designed to stay clean and simple. Hydraulic modulation here gives you more control over braking power than a cable system would, which matters most when surfaces are loose or wet.
