The Shimano GRX ST-RX810 shift/brake lever – with Servo Wave
The Shimano GRX ST-RX810 shift/brake lever features Servo Wave technology – a novelty in the Road bike sector. This ensures more bike control on changing surfaces. Its lever and grip ergonomics were developed in collaboration with Gravel specialists from all over the world; a texturing of the brake lever helps to increase grip. The smooth-running function of the shifter is well-known from the Shimano top-level groupsets.

Shimano Total Integration (STI) means the combination of braking and shifting functions in one lever, which increases safety when riding. By refining the technology, it became possible to make shifting so smooth at the front and rear that they can be triggered with just one finger. Shimano calls such levers Dual Control Levers (DCL).

Servo Wave
Shimano Servo Wave technology optimises the travel of your brake levers. During the braking process, the brake pads are guided quickly to the brake rotor with very short lever travel. The greater part of the lever travel is reserved for the actual braking force. In this way, you can apply your braking power in a more targeted manner and use it more effectively.
