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:
- 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 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.
- Shift switches to be used in conjunction with ST-7971 TT aero levers which can be located on the aero extensions as a replacement for traditional mechanical bar end shifters.
- These switches now give the added option of being able to operate the gears from either the aero extension or the aero ST-7971 brake lever previously not possible on a TT set up.
- Brake levers are lightweight thanks to aero carbon fibre lever blades, carbon composite bracket body, and alloy fixings.
- Brake lever pivot is positioned to increase power in combination with BR-7900 brake callipers.
- The Di2 switches are also compatible with the FlightDeck computer (SC-7900), measuring important data such as heart rate, altitude, cadence, gear position, battery indicator and more.
- Switches are supplied without electrical cables, as these need to be ordered separately to suit.
