    Old/New Campagnolo system compatibility

    Hello,

    I'm thinking of building up a new bike to try a different sized frame and to learn some more than rudimentary mechanical skills. For one reason or another, I've got it in my head that I'd like to put together a 10 speed drivetrain using some Super Record/Nuovo Record (derailleurs, cranks, bottom bracket) and some more modern parts (brifters, cassette). I've got a few specific questions, but would love to hear any advice/warnings that you might have:

    1. As I understand it, all of the indexing is in the brifters, so older derailleurs should work fine as long as I don't exceed their capacity. Is this correct?

    2. Can I use a newer bottom bracket with older cranks, or are the square taper dimensions different?

    3. Would it be correct to assume that I can use modern pedals on Super Record cranks?

    I really like the look of some of the Super Record/Nuovo Record components --- particularly the rear derailleurs and the fluted cranks. On the other hand, I also like brifters and the idea of a 10 (or 9, like I ride now) drivetrain. Is this just a silly idea, or is there a chance that I could make it all work?

    Thanks!

    1. No, the geometry of older Campy derailleurs isn't the same as newer ones so you will need a more modern 9 or 10-speed derailleur to index properly. However, 9 and 10-speed Campy derailleurs will work with either 9 or 10-speed Campy brifters and cassettes. (Any Campy experts disagree with the above?) Shimano's rear derailleurs (except Dura Ace) are the ones that will work with anything from 7-speed on up brifters.

    2. Yes, Campy (ISO) tapers are tha same and should work with any of their cranks.

    3. Modern pedals should work fine with your cranks.

    So, the older derailleurs won't work because the derailleur movement is different for a given length of cable pull? In that case, could I still use friction shifters, or is the geometry of the old derailleurs sufficiently different as to rule out even that?

    You can still use friction shifters - though to be fair I've never done it myself, I'm fairly certain that Sheldon Brown has a page on this. And I'm certain people on this forum have done it.

    edit: this might be it. Whatever the case it will have some useful information for you.
