• An 8 speed cassette does fit the splines of the modern freehub. You will get some gouging of the splines but it will work. You will however need a 1mm spacer behind the cassette for a campagnolo freehub, don't know where you will get one of those unless a standard freehub spacer fits and you know what I have never tried.

    Those wheels manufacturing kits are no longer available finding one is not easy. Luck is required.

    No spacer on the one I had in, which would explain why the shifting was so poor and the freehub trashed.

    If my maths is right, an 8 speed cassette is 36.9mm in total and 9 speed 38.2mm. If you add a 1mm spacer, that leaves 0.3mm unaccounted for: what happens to that?
