I’m selling the 105 Di2 grouppo that’s on my aero bike (frameset ALSO for sale, incidentally) because, well, I have 1.5 bike’s worth of 12sp Di2 parts and don’t need them all. Levers, calipers, cranks (175mm) with factory-installed left arm 4iiii power meter, chainrings (50-34), cassette (11-34), chain has only ever been waxed in MSW. Battery and wires long enough for a 58cm frame included as well. It’s currently mounted to a frame so when I take it off I’ll have to open up the brake lines but I’ll try to keep them as filled with oil as possible.
