Count on precise and reliable shifting on every ride, every day with the Shimano Ultegra RD-6870SS electric 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.
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.
