WTB: 10 speed di2 rear derailleur

Classifieds

It looks like my rear derailleur is toast, and in an effort to keep things simple I’m looking to replace it with another 10 speed derailleur. These seem hard to find, but there’s gotta be a few sitting around after upgrading to 11 speed. I’ll take ultegra or dura ace, whatever you have. Let me know here or via PM.
Thanks

Ultegra and Dura Ace are not compatible for 10-speed Di2 (different cables).

Thanks, I just figured that out. It looks like the first gen Dura Ace won’t work, you are right.
