### Unmatched Performance & Engineering

Built with Shimano's advanced engineering, the GRX ST-RX810 features a hydraulic brake lever equipped with Shimano ICE technology for exceptional heat dissipation, ensuring consistent braking power even during long descents or aggressive riding. Its dual control shift/brake lever delivers smooth, precise gear shifts with similar operation as top-tier systems, giving you confident control across gravel, mountain, and mixed-surface rides.

### Superior Materials & Durable Components

Constructed from high-quality materials, the GRX ST-RX810 lever assembly boasts a robust yet lightweight design, weighing only 284 grams for the entire unit. The resin pad compound and mineral oil hydraulic system provide reliable stopping power and low maintenance, ensuring consistent performance mile after mile. Its flat mount disc caliper offers excellent multi-surface brake control, suited for all-weather riding conditions and rugged terrains.

### Innovative Features & Easy Maintenance

Designed with versatility in mind, this shifter/hydraulic brake lever features tool-less reach adjustment, allowing riders to personalize lever positioning for optimal comfort and fit-accommodating multiple hand sizes and riding styles. The One Way Bleed System simplifies maintenance and bleeding procedures, reducing downtime and ensuring optimal hydraulic performance. The patented Anti-slip brake lever enhances grip and control, even when conditions are wet or muddy.

### Stylish & Function-Oriented Design

Featuring a sleek black finish, the Shimano GRX ST-RX810 is specifically designed for gravel and adventure bikes, blending style with functionality. Its ergonomic, gravel-inspired dual control handlebar setup promotes a natural grip, reducing fatigue on long rides and technical sections.

### Compatibility & Use Case

The shifter is compatible with Shimano road front derailleurs and 11-speed drivetrains, making it ideal for gravel, cyclocross, and endurance riding. The hydraulic system uses mineral oil, providing clean and environmentally friendly operation. Whether for gravel races, bikepacking, or adventure touring, this shifter offers precise gear control and reliable braking, perfect for demanding riders looking to elevate their bike's performance.
