I came across a vintage Sugino Mighty Compe crankset in near perfect condition, probably from the late 70's. Crankarm says 171 and 46.11, and the rings are 54 and 48. I don't know much about this set but from what little research I've done it seems they were comparable to Campy Record at their time. I'm building a bike for a friend of mine and was wondering if I should toss these on and what gear ratio to run for him? What rear cog size, etc. running the 48 up front.

Any advice would be greatly appreciated.

Thanks,

Steve

EDIT: Also, they're going on an italian frame, what BB would I need for them to be compatible?
