Hydraulic disc brake lever Shimano GRX BL-RX810 left

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 maximum performance and controllability, the GRX RX810 disc brake lever is equipped with SHIMANO's famous SERVO WAVE technology, long established in mountain biking. For gravel, road and cyclocross use: Shimano GRX BL-RX810 Disc Brake LeverSHIMANO'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.

TECHNOLOGY

SERVOWAVE ACTION - When you pull a SERVOWAVE brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.
