vigilant Kifla - I am indeed running a 102 Campy ISO BB and it would get a 42mm chain line spot on if it wasn't for the clashing. These old Mighty's are definitely ISO - have both JIS and ISO BB's at home and they sit correctly on them. I thought the 102 was short too but if it gets 42mm at the chainring it must be right, right? (you know, other than the gouging out bits of my chainstay…)
