    CDI Italian bike

    Got a bike marked "CDI". Its a steel Italian bike with Campy engraved on the cable guides....no other markings. Now the issue. It did not come with a bottom bracket and I have no idea how to measure or order a new one. Also I have the components for Shimano 600 to put on it. Little help please!!!!!

    20:1 it's an Italian 36x24 BB. You can measure with 98% assurance of knowing by measuring the width. 70mm would (most likely) be Italian, 68 (most likely) would be BSC (1.370x24).

    Measuring width isn't 100% reliable because there are always exceptions, so you can gain assurance by measuring the ID of the thread. If you come up with something close to just under 1-3/8" (or 35mm) it's Italian. If it's about 1mm under 1-3/8" or nearer to 34mm, then it's British.

    Another way, if you have good eyes is to look at the thread direction of the right side. (crank side) Italian will have a right thread, BSC will be left hand threaded.

    some combination of the 3 three methods will give you 100% assurance of what you need.
