Cassette/Hub compatibility

So I'm collecting parts for a new bike build and find myself short on funds. I'm therefore tempted to stick my current groupset on my new frame as a temporary measure. My issue here is that I'd rather not use my old rear wheel and would like to use the new one. My groupset is 8spd Campag, and the new wheelset is for 10spd Shimano.

Now I know I can get spacers to make an 8spd cassette fit a 10spd hub, however, would a Shimano/SRAM 8spd cassette and chain fit with my Campag chainset and rear mech?

    I think 8 speed were still cross compatible or can be made to be compatible with careful indexing... Chain set is not a problem and you can run any chain brand

    So are you saying my current Campag cassette will fit? Or should I just get a SRAM?Shimano cassette and fiddle with the derailleur a bit?

    No, your Campag cassette won't fit on a Shimano splined freehub.

    what are you trying to do?
    shimano rear bodies are the same siye for 8/9/10 (except for the 10 only) shimano and sram cassettes will also fit (some shimano 10spd cassettes will need a spacer.

    but you dont say, clearly, what you plan on using to shift the chain? Campy 8spd shifter and mech?

    This is exactly what I thought, however the previous post confused me.

    So a Shimano/SRAM Cassette will work with my Campag rear mech?

    Yes

    Providing the above will work (8 speed Shimano cassette on 10 speed Shimano hub), where do the spacers go, wheel-side or frame-side of the hub?

    AFAIK an 8 speed Shimano cassette is the same width as a 10 speed one (new 10 speed Tiagra aside) so the only spacer you'll need is the usual 1.0mm steel one which goes on the freehub before the cassette.

    Ah brilliant! Save some hassle then, cheers.
