Shimano Ultegra ST-R8170 Hydraulic Di2 STI Lever

  • High performance Ultegra Wireless hydraulic Servo Wave disc brake Di2 STI's give you control, modulation and power with minimal effort in all riding conditions
  • Wireless connectivity to the front and rear derailleurs for effortless trouble free gear shifts
  • With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear
  • Full and semi synchronized shifting programmable, Synchro shift compatible meaning a single shifter can control both front and rear shifting which can be fully custom tuned to your riding preferences. Semi synchronized shifting means when a front shift is made the rear mech will automatically correct to the appropriate ratio

  • Drop bar STI with shift buttons located in a near identical place to the positions you'd assume shifting using a mechanical Shimano STI
  • Hydraulic brake lever with Servo Wave provides excellent stopping power with less effort especially from the hood position
  • Hydraulic reservoir tank provides pad to rotor clearance auto-adjust maintaining braking performance during pad wear
  • Finely tuneable reach adjusters for the levers enable custom fitment for all hands
  • Levers use CR1632 batteries which last for approximately 1.5-2 years
  • Available as a left hand or right hand STI lever (does not include E-tube wires or hydraulic hoses)
  • Average weight: 391g (for the pair)
Road riding has never been this much fun.

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.
