Shimano Dura Ace 7970 Di2 10-Speed STI Road Levers - Double

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)
