Shimano R8170 Ultegra Di2 Shifter and Brake - Left

Shimano R8170 Ultegra Di2 Shifter and Brake levers bring enhanced modulation and control to every ride by employing Shimano's proven SERVO-WAVE technology. The Di2 platform untethered the shifters while delivering fast and reliable wireless shifting. The BR-R8170 hydraulic 2-piston disc brake caliper brings a new level of control to the road cycling world with improved modulation and a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain. Your time on the bike is precious, let Shimano make it even better.
