Description
- 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 favor of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts
- Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold
- 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
