How do I know if I need an Italian or English threaded BB. I have a Designer '84 Ciocc Microf.c.40 that I got at Goodwill for $25. I want to upgrade to a triple 9 speed. I think I need a new BB, but I don't know how long the axle should be, or if it is Italian or English. Any help would be appreciated.
