Thanks guys. Wish I could justify the cost of a Sutherlands but it isn't in the cards. So, if I understand correctly, a BB that currently uses thin cups and a 68 spindle, would take something like a 64 mm spindle to use a set of thick cups? Or, maybe thick cups are not useable with a 68 BB. Did Campy make a NR spindle that short? If there is a web site that has all this data I'd appreciate a link. Didn't find what I was looking for but my search criteria may have lad me astray. Thx.
