Bottom bracket compatability
#1
Looking at new frames and they all have either BSA or BB68 spec'd for the bottom brackets. Which of these would accomodate an old Shimano UN73 sealed bb unit with English threads? Can't afford new components and a new frame. Thanks.

English threads narrows it down to BSA/ISO - but not say if your UN73 is for 68 or 73 millimeter wide bottom bracket shells.
