The GRX ST-RX810 Dual Control Lever was developed for mechanical shift/hydraulic disc brake use with the GRX 11-speed system. The Right set is for the rear derailleur and rear disc brake. It can be used for both 1x and 2x GRX drivetrains. The Left set is for the front derailleur and front disc brake when using the 2x drivetrain. Each side is sold here as a lever-only. Shift wise, you get the premium Polymer-coated stainless steel shift cable and OT-SP41 pre-lubed housing. The Right set also includes the required, more flexible OT-RS900 loop that must be used with the rear derailleur for proper rear shift action.

Shimano developed GRX components for the rough terrain and mixed surfaces that make gravel riding so challenging, fatiguing and fun. The shift/brake lever ergonomics make for easier leverage, hand positions, comfort and tactile use despite the constant vibration and small impacts of gravel riding. The lever blades feel correct and proper with a standard road drop bar shape, as well as the flared drop bars popular for gravel. Admittedly, they appear larger than Ultegra R8020 levers, but the increased size and variable shape of the levers definitely afford a real advantage on rough terrain, and deliver light, yet precise and positive shift action.
