Product Details

• Synchronized Shift designed, developed to choose the next biggest or lowest gear ratio irrespective of whether a gear change needs to be made by the front or rear derailleur
• The Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur
• 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 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
• Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available
• 11-speed E-tube Di2 compatible
• Compatible with 50-55 tooth chainrings
• Total capacity 16T
• Front derailleur weight is 104 grams
