Shimano Dura-Ace Di2 ST-R9180 + BR-R9270 Disc Brake Set Front+Rear

The Shimano Dura-Ace Di2 ST-R9180 + BR-R9270 set offers ultimate control for time trialists and triathletes who demand uncompromising braking power and aerodynamics. The ST-R9180 levers are specifically designed for mounting on the ends of base bars, allowing you to maintain a streamlined position while braking. Thanks to the electronic Di2 technology, you can shift lightning-fast and with minimal effort, which is crucial during intense efforts against the clock.

This set combines proven TT ergonomics with the latest BR-R9270 calipers from the 12-speed series. These calipers offer 10% more pad clearance, eliminating annoying disc rub. Furthermore, Shimano Servo Wave technology provides a shorter free stroke and improved modulation, resulting in superior braking performance in both dry and wet conditions.

Installation and maintenance are significantly simplified by using a user-friendly bleed process. The robust construction of high-quality carbon and aluminum guarantees low weight without sacrificing stiffness. Whether you're riding a technical, winding course or descending at high speed, this Dura-Ace combination offers the reliability and precision that professional athletes demand.
