What Makes the Shimano GRX BL-RX810 the Better Gravel Brake Lever?

The Shimano GRX BL-RX810/BR-RX810 is the front hydraulic disc brake and lever built specifically for gravel and mixed-terrain riding, combining gravel-inspired lever ergonomics with SERVO-WAVE action that compresses brake pads faster in the initial lever travel so more of your lever stroke is left for precise modulation on unpredictable descents. The lever pivot is positioned 18mm higher than standard road levers, improving brake feel and control when hands are in the drops on rough terrain. The BR-RX810 flat-mount caliper uses ICE Technology for excellent heat dissipation during sustained gravel descents where rim brakes or cable disc setups fall short.

Arrives pre-bled with a 1000mm SM-BH90 mineral oil hose and finned resin pads. Adjustable reach accommodates a range of hand sizes. Compatible with Shimano GRX 11-speed drivetrains and works with current Shimano road drop bar control levers. Flat-mount caliper. Mineral oil hydraulic system. Sold as front lever and front caliper. MPN: IRX8104DLF6SC100.

FAQ

Is this compatible with Shimano 1x GRX setups as well as 2x?

Yes. The BL-RX810 is a brake-only lever designed for use with a separate GRX shifter. It works with both 1x and 2x GRX drivetrains. For a combined shift/brake lever, look at the Shimano GRX ST-RX810.

Can I use this with Shimano road disc brake calipers instead of the BR-RX810?

Yes. The BL-RX810 is compatible with other Shimano hydraulic disc road brake calipers using mineral oil, including Ultegra and 105-tier flat-mount calipers.

What rotor sizes work with the BR-RX810 caliper?

The BR-RX810 flat-mount caliper works with 140mm and 160mm rotors using appropriate flat-mount adapters. The GRX RT-CL800 and RT-MT800 rotors are the OEM-matched options for GRX builds.

Best For
