Shimano Ultegra is known for being light weight, durable, and reliable. This is perfect for racing, or for the rider who wants fast, accurate shifting. Shift under load seamlessly with the Shimano Ultegra Di2 front derailleur. Smooth shifting is ensured due to the microchip communication between the derailleur and the lever. Also, shifting the rear derailleur automatically trims the front derailleur. This ensures that you never have chain rub.

Comments about Shimano Ultegra DI2 FD-6770 F Derailleur:
Consistent shifting in all weather conditions. The motors make a little noise as they shift. That doesn't bother me at all. I'll write a better review in a few months.
