I have a road frame/fork (plus a few other odd parts to work with) that I wish to build up. That was just a question I thought I should know the answer to before I started sourcing any wheelset/shifters/derailleurs/crankset/cassette for it.

Particularly with the hubs and cranks, it seems like there are several other choices out there, and I honestly don't know what issues might arise if say I used a Truvativ crankset with a group that was otherwise Campy Mirage. I was thinking that as long as the derailleurs-shifters and hub-cassette were compatible, there shouldn't be much of an issue putting it all together, but I just wanted to double check.
