  • 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 programable, Synchro shift compatible meaning a single shifter can control both front and rear shifting which can be fully custom tuned to your riding preferences.

  • 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
