So I have heard of English 68, and Italian 70, and English oversized?
What exactly is meant by Italian, oversized.

as a follow up: I have a crankset that currently sits on a 68 mm, 103mm spindle, JIS taper bottom bracket. Is there a bottom bracket that will fit that frame (70 mm italian, oversized) and my crankset? I found a 102mm Campagnolo Chorus Bottom Brackets, but it is expensive!!
