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 our fastest, most reliable wireless shifting. Your time on the bike is precious, let Shimano make it even better. To the delight of riders and mechanics alike, the new ULTEGRA BR-R8170 caliper delivers enhanced modulation, a quieter brake system, and an easier than ever bleed process. The ULTEGRA R8170 disc brake caliper brings a new level of control to the road cycling world with enhanced modulation and a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain.Hydraulic disc brakeBrake fluid: SHIMANO Mineral OilBrake hose (Kit): SM-BH90-JK-SSRHose joint: StraightFunnel bleeding (Shimano One Way)SHIFTER INFORMATIONClean Cockpit: Wireless connection enhances the aerodynamic effect and easy maintenanceUnparalleled ergonomics engineering refined with pros' feedback: raised hood peak improves ergonomicsOptimized brake control: lighter, smoother lever action and enhanced modulation thanks to an expanded braking control areaCompatible with wired and wireless connectionAvailable to additional satellite shiftersHigh electronic energy efficiency: 1.5 to 2 years of battery life with easy-to-change CR1632 shifter batteriesWeight: 196 gFirmware update by E-TUBE PROJECTRemote switchClamp band (mm): 23.8-24.2Reach adjustFree stroke adjustSERVO WAVEDUAL CONTROL LEVERBatteryWired Di2 shiftingWireless Di2 shiftingPort for remote sprinter shifter: Not availablePort for SD300 satellite shifter (pcs): 1SD300 connector (pcs): Not availableSD300 port (pcs): 1SD50 connector (pcs): Not availableSD50 port (pcs): 0CALIPER INFORMATION10% wider pad clearance decreases brake noiseMaintenance-friendly bleeding processWeight: 136 gICE TECHNOLOGIES pad compatible caliperCaliper fixing bolt Anti loosen method: Bolt fix pin, snap ringCaliper fixing bolt tool size: 4 mmFixing screw spec for rear mount: 10/15/20/25/30/35 mm mountFlat mountPad mount: Pad axlePistons: 2Includes brake pads: L03A ResinOPTIONAL compatible brake pads (not included): L04C Metal, K03S Resin
