Shimano Dura-Ace R9270 Di2 12 Speed Disc BrakeThe Dura-Ace R9270 Di2 12 Speed Disc Brake from Shimano features Servo Wave technology and is compatible with Shimano Di2 electronic drivetrain systems. Plus, it guarantees powerful all-weather stopping power and flex-free lightweight braking performance thanks to its carbon fibre brake lever and titanium hardware.All-new lever ergonomics on the Dura-Ace ST-R9270 dual control levers bring new levels of comfort and control to road cycling. With the fastest wireless shifting available and even more precise brake modulation, Dura-Ace redefines performance. Now featuring Servo Wave Action brake technology, the new Dura-Ace ST-R9270 brake lever delivers modulation and control like never before. Wireless shifting keeps your bike looking clean while offering the fastest, most precise gear changes available. All of this resides in a Dual Control Lever to employs the most advanced materials to offer lightweight and refined ergonomics that provide comfort and control for the most demanding conditions. Servo Wave Precise Braking ControlWhen you pull a Servo Wave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control. Shimano DCL Dual Control LeverDCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is as critical to higher standard performance as the added gearing. The shift internals borrows the robustness from Shimano's MTB technology and is so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration and simply has to be experienced to be understood.
