The Ultegra Di2 R8050 11-Speed Rear Mech will help you maintain race-pace and concentration via smooth and crisp shift control. Updated with the new low-profile design of Shimano's innovative Shadow RD technology to increase shift stability, this rear mech now has sleek and integrated aesthetics.

Compact Rear Mech Design

The optimised slant angle of this Ultegra Di2 R8050 11-Speed Rear Mech guarantees race endurance and, being more compact in design, the closer fit to the frame ensures less damage in the event of a spill.

Features:

  • Shadow RD Technology
  • Precise and accurate shifting
  • Optimised slant angle
  • Low-profile design
  • Weight: 242g (Short cage)

Technologies:

  • Shadow RD: Traditional derailleurs extend wider than the profile of your bike. With its low-profile design, Shadow RD is a more compact derailleur that fits closer to the frame, with more direct cable routing. Shadow RD maintains a consistent distance to the cassette for increased shift stability. The reduced body width creates a sleek and smooth appearance, ensuring less damage in a crash.
  • Di2: The power and precision of Di2 is unmatched. It enables beautifully smooth shifting both front and rear. The lack of maintenance and adjustment is impressive: once you’ve customised your Di2 to shift to your preferences, it will continue to do so endlessly.
