My buddy is racing Ironman Chattanooga on 9.30 and his rear derailleur on his Di2 is shot. He needs one but since it's a gen1, the LBS can't seem to locate one. The part number is RD-7970 would be willing to buy either the rear derailleur or even the entire system if it's reasonably priced.
I have a 7970 Di2 aero/tt set. Let me know if other poster option here doesn’t work out. I think you posted 6770 earlier so not sure which he replied regarding.
Shimano actually made a warranty replacement RD for the 7970 system using a newer E-TUBE RD combined with a wiring converter SM-RD79-A (looks and mounts like original D-Fly). RD is labeled 7970-A. I’ve only seen it mentioned from European forum posters so not sure on availability. The one online shop listing I’ve seen had it priced at over $500.
