Hi Guys,
Probably been asked 1000 times before, but I've been away from the scene a few years - can I upgrade my 9 speed wheels (Campag Chorus) to 10 or 11 speed?
Thanks for any responses

Phil

    Yes, your new cassette will fit straight on.

    The campag freehub is a standard width. I have just changed the freehub on my Mavic Carbon Cosmics from Shimano to Campag which originally ran 9 speed now I am running Chorus 11 speed. The new freehub body only comes in one width to suit 9, 10 and 11 speed. Essentally that is why the increase in numbers of ratios has been a steady increase from 9, to 10 and now 11, because the width of the freehub is the same, but they have crammed more cogs into the same space. generally by making the cogs narrower, having them hang over the edge of the freehub body slightly and running a narrower chain.

    I ran it with a spacer on 9 speed and with 11 speed the spacer is removed and there is about half a mil clearance!
