Shimano Dura-Ace R9170 Di2 Hydraulic STI Lever and Flat Mount Brake Set

Not Enough Available

Top of the range, high performance Dura-Ace hydraulic disc brake Di2 STI's give you control, modulation and power with minimal effort in all riding conditions.

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. The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts.

Shifters are lightweight thanks to carbon fibre lever blades, carbon composite bracket body, and a titanium clamp band / fixing bolt. 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 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 and features free stroke adjustment for pad to rotor contact setting.
