This trifecta lets you focus on the next sprint, the next descent, or the next joke from your riding partner. Shimano's new Ultegra ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven Servo Wave technology. The all-new Di2 platform, used on both Dura-Ace and Ultegra, untethers the shifters while delivering the world's fastest, most reliable wireless shifting. Your time on the bike is precious, let Shimano make it even better. 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.
