I'd really like to hear about anyone succesfully using that vo bb in a viscount. The id of the bb shell, or the od of the bearings, is right at the limit of what that bb is supposed to work with. There may also be some assymetrical issues for the lengths of the original spindle. Then there are the frame tubes usually intruding into the bb shell that would probably need to be ground out to use that bb. Too bad it's so complicated, those are nice frames. I'd like to hear what happens with this one.
