- 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
