Shimano BR-R8070+ ST-R8020 Disc Brake

BR-R8070 + ST-R8020 by Shimano - Ultegra label for a disc brake

The Shimano Ultegra BR-R8070 + ST-R8020 disc brake stands for the highest possible level of control and strong Ice-Technologies braking performance in all conditions. Due to its elegant flat mount design, the hydraulic brake caliper (2 ceramic pistons) does not affect the look of your bike in the least, but integrates seamlessly into the overall appearance. It can be easily bled via the One Way Bleeding System. On the other hand, the STI shift/brake lever features fast, intuitive shifting and extended reach adjustment. There is also the bonus of excellent brake control, which is further enhanced by the Servo Wave construction. Thanks to its reduced circumference, the Shimano Ultegra Dual Control grip fits well in the hand and contributes to more ergonomics while riding.

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.
