Your time on the bike is precious, let Shimano make it even better. Ultegra ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven SERVO-WAVE technology. The Di2 platform untethers 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.

  • The wireless connection provides a clean cockpit, enhancing the aerodynamic effect and easy maintenance
  • Wider pad clearance decreases brake noise
  • Maintenance-friendly bleeding process
  • Unparalelled ergonomic features, such as raised hood peaks on levers
  • Brake control is optimized with light and smooth lever action
  • Enhanced modulation thanks to an expanded braking control area
  • Compatible with wireless or wired connection
  • Includes L03A pads
