Shimano Dura-Ace FR MECH D/Ace Di2 R9150 11spd braze

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
