Shimano Ultegra Di2 offers the most precise and reliable shifting imaginable, at the push of a button. Adjust the derailleurs once, and the intelligent, auto-trimming system returns derailleurs to the same position every time. The intuitive and user-friendly design can be set up at home and accommodates any frame; new or old.

Count on precise and reliable shifting on every ride, every day with the Shimano Ultegra electric RD-6770 rear derailleur. Adjust your derailleur once at installation and never worry about it coming out of adjustment; no cable stretch, no barrel adjusters. The completely sealed and waterproof system makes dirt and grit a non-issue. The clever crash-saver function automatically moves the cage all the way inward at the moment of impact, in an effort to save it from destruction.
