Shimano GRX STI ST-RX810 2-/11-speed Shift/Brake Lever

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.

Technology:

STI Dual Control (DCL)
DCL stands for Dual Control Lever. It has braking and shift functions and allows easy operation. The improved ergonomics is probably even more important for the high standard than more range. The shift levers bring the stability of Shimano MTB technology and work so precisely and smoothly that it is possible to shift gears both front and rear with just one finger. This is a highlight of Shimano's " Total Integration" (STI). You have to experience it for yourself to believe it.

Servo Wave
The Servo Wave brake lever takes up a lot of braking distance at the beginning of its movement so that the pads can be guided to the brake rotor with short lever travel. After the brake pads have been applied, the power transmission factor increases rapidly. The greater part of the lever travel is thus still available to increase the braking force and to modulated it more precisely.
