The Shimano Ultegra RD-R8050 Di2 Rear Derailleur offers clean, crisp, and intuitive shift control, giving you performance akin to the Dura-Ace Di2 series. The low-profile design places the derailleur under the cassette, protecting the derailleur from misalignment. This derailleur has Shimano Synchronized Shifting which in effect synchronizes the front and rear derailleur, and E-tube software which allows customization of shift control. Excellent hardware and software make for a great derailleur with smart precise shifts.
