For double cranksets
Forget about chain-rub; the Shimano Ultegra 6870 braze-on front derailleur is wired in sync with the rear derailleur and automatically trims the front when you shift in the cassette. When cresting a hill, the derailleur shifts effortlessly under load from the little chainring to the big, with a light tap of the shift lever.
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.
