Shimano Dura Ace Di2 FD-R9250 2x12 Speed Front Derailleur

Features and Benefits:

• Elite road racers demand reliable and precise shifting, 12-speed Dura-Ace R9150 delivers with its super-lightweight and compact design
• 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 wireless communication 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 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 to purchase seperatley if required
• 12-speed E-tube SD300 wire compatible
