Engineered for the rugged realities of gravel riding, the Shimano GRX ST-RX810 right-side shift/brake lever represents a bold evolution in cycling control systems — harmonizing crisp 11-speed mechanical shifting with the unflinching power of hydraulic disc braking. Designed not as a reworked road lever but as a purpose-built gravel solution, the ST-RX810 is Shimano’s answer to the complex demands of modern off-road cycling.

This lever is sculpted with gravel-specific ergonomics that instantly distinguish it from traditional road components. The refined hood profile provides a more natural hand position, especially when riding on the tops or in the drops over rough, uneven terrain. A non-slip coating on the lever surface ensures secure grip in all weather conditions — from rain-soaked descents to dry, dusty trails.

Beneath its rugged exterior lies Shimano’s signature mechanical shifting system, delivering sharp, positive gear changes even under load. The short lever throw and tactile click keep your focus on the trail ahead, not on your drivetrain. Whether launching out of the saddle on a steep climb or making quick shifts over mixed surfaces, the ST-RX810's intuitive response and consistent feel inspire confidence with every push.

The hydraulic braking system offers another layer of command. Using Shimano's SERVO WAVE technology, the lever moves quickly through its initial travel to engage the pads sooner, followed by a smooth progression for precise modulation. This means instant stopping power when you need it and feather-light control when you don’t. Long descents, heavy packs, or emergency stops — the ST-RX810 handles them all with minimal hand fatigue and maximum control.

Built for long-term reliability, the lever body is constructed from durable alloy and finished in a sleek, matte black — perfectly suited to the aesthetic of high-performance gravel bikes. Internal cable routing options maintain clean lines and aerodynamic efficiency, while compatibility with Shimano’s 11-speed mechanical drivetrains ensures seamless integration.

Whether you're racing gravel, bikepacking into remote wilderness, or simply exploring the road less traveled, the GRX ST-RX810 right shift/brake lever is your trusted command center — bringing together precision, durability, and terrain-taming confidence in a single, finely tuned component.
