Cam u put a 10spd cassette on a 9spd wheel.

Usually. Try it - you'll soon know if it's worked or not!

You might need an extra spacer because I think the 10spd cassettes are a fraction narrower than the 9spd ones (contrary to what intuition might suggest). You'll soon know - if you can't tighten up the lockring enough to stop the sprockets from rattling.

Good point - and I had some difficulty finding a bike shop that could sell me one on the basis that "they only come with new cassettes"...

Wiggle came good in the end: http://www.wiggle.co.uk/?s=cassette+spacer

Surely the answer depends on the make of cassette?
