• Here's the rest of the groupset. As far as I'm aware it's all Athena, but not necessarily all from the same year. Forgot to photograph the brakes, but they're not monoplaners. And yes, those are SPDs. What of it, eh?

    I did find a BB - It's Athena, but it's cup and cone, rather than cartridge.

    Looking more closely at this troublesome rear mech, I think I've got a first-gen Athena mech - designed for use with friction shifters or the Campagnolo Synchro system. What I need (and what I thought I had - until this morning) is a "Athena RS RD-01AT"

    Which means that I'm worrying about a washer for a mech that probably won't shift properly anyway.

    Fuuu...
