Hi sorry only just seen these messages later today.I also have BB and cassettes as well.
Technically I have a couple of other options, though taking near nos condition cranks and in one case a whole nos set of rings, nos BB too. Have been keeping these for a project or two, but I'd never say never.
Potentially interested in the shiftersI’ve a complete M952 build kit from my former KK - cranks were sold however I think from memory. Get in touch if interested in a cassette, BB, shifters, mechs etc.
