Shimano GRX RX810 Hydraulic Disc Brake Lever Left Front Flat Mount

Shimano GRX RX810 Hydraulic Brake Lever – Mastering Mixed Terrain Braking
Engineered specifically for gravel cyclists navigating unpredictable paths and varied terrains, Shimano’s GRX RX810 hydraulic brake lever delivers unmatched precision and reliability. Whether you’re tackling steep descents or uneven trails, this lever combines advanced technology with intuitive design to keep you in control from start to finish.

Key Innovations for Gravel Performance
The GRX RX810 lever boasts ergonomically shaped grips tailored for long-distance comfort during off-road rides while maintaining seamless integration into your bike’s setup. Its flat-mount disc caliper uses Shimano’s ICE Technology—a proprietary cooling system—to dissipate heat efficiently during extended braking sessions on rough terrain or high-speed descents. Pre-bled straight out of the box ensures immediate readiness for your next adventure without post-installation adjustments.

Tailored Control & Compatibility
With adjustable lever reach options available on both left and right sides (this listing is for left-hand units), riders of all sizes can customize fit for optimal grip and responsiveness during technical sections or extended rides. Designed for mineral oil hydraulic systems, these brakes prioritize smooth modulation while resisting corrosion over time—a critical advantage when riding through wet conditions or dusty trails common in gravel cycling environments.
