I have an italian treaded bb, campy. Spindle is 113mm...to narrow for any double. Want 49d so i will try to see what combo works. I will let you know what i come up with. Btw, tried to unscrew campy fixed cup and could not get it out so will leave it and try a stronglight spindle with a) the campy adj cup or b) stronglight adj cup. Thank you for your info...purchased italian stronglight in 118mm size which is what i have in a 68mm shell w/stronglight 49d and that works with maybe 1mm bolt clearence at chainstay. Will let you know.
