Selling a brand new Shimano Dura Ace Di2 group. Includes the shifters, front derailleur, rear derailleur, battery, charger and power cord, bottle cage adapter mount, front wiring harness, and then the medium wiring harness also. This is everything you need to upgrade your current Dura Ace drivetrain to electric. Does not include cranks, brakes, cassette, or chain. First 1900 takes it.
