The Shimano Dura-Ace Di2 group delivers shifting performance like none other. Seriously, this setup is awesome. With electronic shifting you get smooth, precise shifts with instant engagement, no matter what the riding conditions are like. This front derailleur also has automatic trim for less chain rub.
- The integrated CPU keeps track of both front and rear derailleurs to optimize shifting performance
- Automatic trim function on this front derailleur moves the chain guide to complement the position of the rear derailleur--one less thing for you to concentrate on while riding
- Programmed motion prevents chain drop when shifting down
- Forged aluminum and composite construction is lightweight but strong enough for regular riding
- Must be used with Shimano Dura-Ace Di2 7970 Front Derailleur Wire Kit (sold separately)
