Shimano GRX BR-RX810 + ST-RX810 Disc Brake

Shimano GRX BR-RX810 + ST-RX810 disc brake - inspired by Gravel specialists

The Shimano GRX BR-RX810 + ST-RX810 disc brake gives you more brake control on mixed terrain. The GRX BR-RX810 brake caliper with Ice Technology ensures perfect heat distribution. In addition, there is the simple one-way bleeding and the uncomplicated hose connection system. The design of the brake caliper is based on the flat-mount construction, which has established itself in the Road bike sector over the past few years

The Shimano GRX ST-RX810 shift/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. The texture of the brake lever helps for more grip. In addition the Shimano Servo Wave technology, mostly known from MTB, is used.

Technology:

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
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.

One Way Bleeding
One Way Bleeding is a technique used on Shimano calipers that facilitates brake bleeding. 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.
