Shimano Ultegra R8170 Di2 12 Speed Disc Brake - Black - Left Rear}, Black
  • £449.99

Shimano Ultegra R8170 Di2 12 Speed Disc BrakeThe Ultegra R8170 Di2 12 Speed Disc Brake from Shimano is compatible Shimano Di2 electronic drivetrain systems and Servo Wave hydraulic disc brakes. This brake system offers exceptional comfort and easy-to-use ergonomics with lighter and smoother brake lever action and exceptional gear shifting accuracy in all weather conditions.Road riding has never been this much fun. That's because the redesigned Ultegra ST-R8170 Dual Control Levers have all-new ergonomics, even more precise brake modulation, and wireless electronic shifting. 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. Features: Clean Cockpit: Electronic connection enhances the aerodynamic effect and ensures easy maintenance Unparalleled ergonomics engineering refined with pros' feedback Raised hood peak improves ergonomics Optimised brake control Lighter, smoother lever action Enhanced modulation thanks to an expanded braking control area Compatible with wired and wireless connection Available for use with additional satellite shifters High electronic energy efficiency 1.5 to 2 years of battery life with easy-to-change CR1632 shifter batteriesA 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
