For gravel, road and cyclocross
A central concern of Gravel riders is a reliable braking system with sufficient power reserves, the Shimano Di2 GRX 2x11-speed ST-RX815 STI for hydraulic disc brake is characterized by excellent deceleration performance to maintain control on steep, demanding or even surprising descents.
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. The STI lineup of the GRX family is complemented by the 1x11-way RX800 and RX600 STIs for the left without switching or DSP functionality, including the 1x11 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.
