Shimano Dura-Ace FD7970 Di2 Braze-on Double Front Mech

The difference in the effort and time taken for front shifts between Dura-Ace mechanical and Di2 is truly staggering: with programmed automatic motion at the touch of a switch the Dura-Ace Di2 front derailleur is quick, smooth and effortless, making for unmatched drivetrain efficiency.

The Features of the Shimano Dura-Ace Di2 Braze-on Double Front Mech FD7970 are:

• The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load
  
  
• The difference in the effort and time to actuate the shift between mechanical and Di2 is truly staggering
  
  
• The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but gives 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
  
  
• 10-speed Dura-Ace Di2 compatible
  
  
• Front derailleur weight is 124 grams
