Shimano GRX BR-RX810 + ST-RX810 disc brake set - designed for Gravel riders

The Shimano GRX BR-RX810 BR + Di2 ST-RX810 disc brake set (front + rear) helps to get more brake control on mixed terrain. The BR-RX810 GRX brake calipers with Ice Technology ensure perfect heat distribution. In addition, there is the simple one-way bleeding and the uncomplicated hose connection system. The design of the brake calipers is based on the flat-mount construction, which has proven itself in the Road cycling world over the last few years.
The Shimano GRX ST-RX810 brake lever also stands for more control on various terrain. Its lever and grip ergonomics were inspired by Gravel specialists from all over the world; the smooth shifts corresponds to that of previous Shimano top-level groupsets. A texturing of the brake lever helps for more grip. The Shimano Servo Wave technology known from the MTB sector is also used.

STI Dual Control
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
Servo Wave optimises the leverage 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. This technology allows you to control your braking force more precisely and to apply it more effectively.

One Way Bleeding is a technique used on the brake calliper that makes it easier to bleed the brake. The hose routing has been optimised so that no air bubbles remain in the brake calliper. In combination with the funnel, the brake can be bled cleanly and easily.
