Shimano Ultegra Di2 RD-6770 Rear Derailleur

Shimano broke the mold with their Dura-Ace Di2 group. Effortless shifting, instant engagement, unparalleled performance. Well, now you can get electronic shifting without shelling out all that dough. The Ultegra Di2 group is a more affordable version of the Dura-Ace Di2 group, so you can enjoy many of the benefits, without the high price tag. This rear derailleur is also equipped with a built-in safety function and recalibration function in the event of impact, which keep your drivetrain working just it was the day it left the bike shop.

  • The integrated CPU keeps track of both front and rear derailleurs to optimize shifting performance
  • Servo motor ensures that every shift is identical, so you get reliable performance
  • Programmed motion speeds up shift times and prevents chain drop
  • Built-in safety function automatically shifts the derailleur inward under impact to prevent damage to the component
  • In the event of impact, the rear derailleur recalibrates for perfect alignment with the cassette
  • Now compatible with up to a 28T rear cog for better functionality with compact cranks than other designs
  • Short cage design is compact
  • Must be used with Shimano Ultegra Di2 Rear Derailleur Wire Kit, Shift Levers and related system components (sold separately)
  • Not compatible with Dura-Ace Di2 7900 levers or wire kits
