Shimano GRX ST-RX610 Hydraulic Brake/Shift Lever 12spd

The Shimano GRX ST-RX610 dual control lever delivers light, responsive shifting for mixed-terrain gravel riding, integrating a shifter with a hydraulic brake lever optimized for GRX RX610 systems. Available in right (rear shifting, 12-speed) and left (front shifting, 2-speed) variants.

Gravel-specific lever body ergonomics enhance control on varied surfaces. The textured hood and anti-slip brake lever surface maintain grip in wet or muddy conditions. A reach adjust mechanism allows customization to suit different hand sizes and rider preferences.
