AFAIK, the Sugino Mighty was a pretty faithful clone of the Campy NR, except maybe Sugino might have switched the track crank from 151 to 144 a couple of years later than Campy. So I'd expect Sugino to use the same BB as Campy for a track crank and a given frame. One of the Campy-specific sites, or an old Sutherland's should list the axle length for NR track.

I have a nice Sugino Mighty Competition track crank (on-topic I think) that I want to put on it, but need to find a suitable BB. I don't know what length I would need for the spindle. I suspect it is similar to what a NR pista would have used (the cranks look similar), but I am not certain. I did a search of the archives with no clear results.
Would a NR bb work? What lenght spindle (for a BSC 68 mm bb) would an NR have used? If I buy a more mondern BB, does it have to be track specific, and what length BB should I be looking for? I really want to use a classic cup/cone BB, the cartridges just don't look right to me.
Any hints are welcome. Thanks, Dan Kasha Seattle, Wa PS Mercer Island loop is really fun on a track bike.
