    Italian vs English thread?

    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.

    Thanks,

    Steve

    axle length and type is determined by your crankset... if your drive side cup loosens toward the front (i.e. "is reverse threaded") then it's likely english thread, if it is not reverse threaded then it is likely italian. there are other, rather rare, threadings like swiss and french, but i'd almost guarantee that your ciocc is not one or the other. my guess would be italian.

    Italian also has 70mm wide bottom-bracket shell, English is 68mm.

    Look at the fixed cup. Often the size is stamped on the outer face.
    Today, I believe my jurisdiction ends here...
