Shimano FD-R9150 Dura-Ace Di2 11 Speed Braze On Front Derailleur

Elite road racers demand reliable and precise shifting, 11-speed Dura-Ace R9150 delivers with its super-lightweight yet durable 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 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
