what exactly are the technical differences in terms of taper angle etc.?

what kinds of cranks/bb's are which and where does campy fit in?

any and all info would be appreciated. i got a couple sets of Sugino 75's and couple BB's, one FSA ultimax and one cartridge bearing campy road BB, and i shimano 68x107mm (UN???).

i'm just trying to be a little more informed about what works with what. so please drop all that obscure knowledge on me that's just been collecting dust in your mind.
