A central concern of Gravel riders is a reliable braking system with sufficient power reserves to maintain control on steep, demanding or even surprising descents. For a streamlined cockpit and easy access to the seat dropper post lever, SHIMANO’s GRX RX810-LA dual control lever integrates the brake lever and dropper lever for fast and effortless operation.
For gravel, road and cyclocross: the GRX ST-RX810-LA lever for disc brake and adjustable seat post from Shimano
All STI Dual Controler feature an 18mm higher brake lever pivot axis, a curved lever shape and non-slip textures on the contact surfaces for optimum grip even in the roughest terrain.
For the integration of drop seat posts in the Gravel segment, SHIMANO specially developed the hydraulic STI lever ST-RX810-LA, which, mounted on the left-hand side, uses the sideways movement of the lever not required for shifting in 1-speed systems to operate the seat post. The integrated traction system is designed for a 9 mm stroke and therefore works with most common dropper posts. The STI lineup of the GRX family is complemented by the 1×11-speed RX800 and RX600 STIs for the left without switching or DSP functionality, including the 1×11 Di2 version (ST-RX815), whose three switches (two on the side and one on the top of the cap) can be used to operate 3rd devices such as compatible lights or computers.
SHIMANO’s GRX, the first Gravel-specific component family designed for both fast progress and safe bike handling on loose surfaces, is the result of an intensive and extensive research, testing and development process that incorporates information and feedback from countless riders on trails, forest tracks, gravel tracks and asphalt all over the world.
