Shimano Dura-Ace Di2 7970 Front Derailleur - 10 Speed

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, for all riding styles and terrain.

Key Features:

• Dura-Ace Di2 7970 Front Derailleur - Double - Braze on.
• The difference in the effort and time taken for front shifts between Dura-Ace mechanical and Di2 is truly staggering.
• The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load.
• Removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminants, corrosion and stretching, but provides effortless gear shifts.
• The front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road ahead.
• High tolerance cold forged aluminium and composite construction.
• Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available.
• High tolerance cold forged aluminium link plates and body construction is extremely light and durable.
• Weight: 124g (Manufacturer claimed).
