    I'd be interested in this. Would you include parcel motel delivery? It's about 4.50 I think?

    I'm assuming I might a) get it fixed or b) pick up a 7970 rear mech somewhere!

    Are any of the bits compatible with other versions, do you know? For example would the shifters work with a 6770 (original 10sp Ultegra DI2) setup?

    Hi Paul Sorry but not moving on price ive already lost €45 as i paid €200 plus €15 registered post

    Very good possibility an older bike shop might have the Diagnostics tool specifically for 7970 Di2 /Also slim off chance of picking up one on Ebay /elsewhere like i said gold dust

    This is 100% not cross compatible its a stand alone one off di2 7970 ,Shimano changed the cabling and Diagnostics tools thereafter

    "Because the first generation 7970 used completely different technologies than the newer 2-wire systems, none of the components are cross-compatible."


    Many Thanks

    OK. I'll go 170 plus the parcel motel charge. I really wanted to confirm that you were happy to send it by parcel motel. You just have to drop it into a locker at your nearest PM location.
