The entire RD assembly no longer swings all the way rearward to take up the chain slack when I shift towards smaller cogs.

I have a 6700 RD I'll send you, gratis. A very nice forum-pal sent it to me for free (thanks Augi) to harvest the long cage to graft onto a 6770 Di2 for more chain wrap. I bolted the short Di2 cage back to the analogue mech and am happy to pass it on.

FYI, the disassembly, clean, lube, reassembly of the B-axle is a 15 minute job requiring nothing beyond basic tools (3mm, 5mm, Philips).

I had no idea what you were going to do with it... very cool!

That's a good read. Maybe a little over the top, but in the realm of reality. Equipment choices were very few back then, but we made do. It definitely required more commitment to ride.
