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. Semi synchronized shifting means when a front shift is made the rear mech will automatically correct to the appropriate ratio

Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold

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
