Shimano
Dura Ace Di2 10sp Electronic Front Derailleur - Braze

• The biggest difference provided by the Di2 system is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load
• 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
• The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts
• 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
• 10-speed Dura-Ace Di2 compatible
• Weight - 124g
