I'll sure be interested in your findings.

I've just gone the other way, with a Stronglight 93 onto a classic 70's Campy BB. That was a standard 68-120-SS.

This was after I'd tried to run the same crank with the original cyclo-cross/bash-guard. That required a triple axle. I used an equally old-skool Campy triple with thin cups.

In both cases, the fit was/is perfect. You can see my two steps forward, one step back progress in the thread on the "1963 Hetchins Mountain King - a progress report" to see photos.

For my next project, I'm thinking of a compact double, which would be JIS. But I have a stash of ISO bottom brackets. That nice V-O compact double looks good, but the V-O people just say, it works for some people and less so for others. Hmm. Thanks. I think?

Anyway, do please keep us posted.
