>>1364340>>1364344>>1364348As someone who has a relatively old bike which I've been working on, I personally have mixed Shimano and Campag because the only thing that matters to me is functionality. This is a bike that originally had Campag everything but I've put some Shimano parts on because they were WAY cheaper than the Campag equivalents (Campag retro stuff is absurdly expensive for some reason, I guess it's deemed "collectible" or some shit).
Anyway, why do you want a Campag wheelset? Bear in mind that Campag wheels have different freehubs, assuming that these are freehub wheels. They might be freewheel, which is different - freewheel basically means that the wheel has a thread, and the ratcheting mechanism is actually a part of the cassette, and the whole unit threads onto the wheel. Freehubs are different - the ratcheting mechanism is part of the wheel, and the cassette just slides onto the freehub. But yeah, Campag freehubs are different from Shimano freehubs. So you will have to use a Campag cassette (or Campag-compatible, and the only other Campag-compatible components I know of are made by an Italian company called Miche, and they're definitely not as cheap as Shimano and Shimano-compatible cassettes).
This is something to bear in mind. And it's a problem I'm facing myself at the moment. I have a Campag wheelset but I fucking wish I had a Shimano freehub on my rear wheel because you can get Shimano cassettes for very cheap (or you can even get Shimano-compatible cassettes for even cheaper from, for example, this Taiwanese company called Sunrace - personally I'd probably just go Shimano though because they're still very affordable for brand new Shimano ones).
If you have a Campag freehub then vintage Campag cassettes are expensive, especially if they're in good nick. They can be very expensive. Or you can go for a Miche cassette and they look alright, but they're still more expensive than Shimano parts.
Just something to consider.
