Digital Integrated Intelligence. The eagerly awaited Shimano Di2 (Digital Integrated Intelligence) is here. Evolution never stops. This new technology brings shifting to a new level. It gives you a swift, definite shift every time and in every situation. Rigorously tested to perform in all weather conditions, for all riding styles and terrain. Key Features: Dura-Ace Di2 10-Speed Road STI Levers - Double. The most advanced level of shifting technology: at the touch of a switch Dura-Ace Di2 is quick shifting, smooth, and effortless. The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminants, corrosion and stretching, and also provides effortless gear shifts. Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold. Buttons are located in a near identical place to the positions you'd assume for shifting using a mechanical Shimano STI. Shifters are lightweight thanks to carbon fibre lever blades, carbon composite bracket body, and a titanium clamp band / fixing bolt. Brake lever pivot is positioned to increase power providing excellent ergonomics when riding on the hoods. - Finely tunable reach adjusters for the levers enable custom fitments for all hands. The Di2 STIs are also compatible with the FlightDeck computer (SC-7900), measuring important data such as heart rate, altitude, cadence, gear position, battery indicator and more. Levers are supplied without electrical cables, as these need to be ordered separately to suit. Weight: 255g a pair (Manufacturer claimed)
