Our local American Classic rep came in to the LBS on Wednesday, and

*but*
He also showed us some shims for their 9sp alloy freehub to make it
work properly with 10sp casettes to avoid dig in like this :

We pressed him to see if AC would sell the shims as spare parts, and
he'll get back to us on it. But, it may be a hack to get around the
current problem with 10sp Ultegra & Dura-Ace cassettes on 9sp alloy
freehubs.
a shim won't do it - it doesn't bear the torque load. they need to
address the problem properly like shimano did - make the teeth deeper
or use a steel/ti cassette body. have them do the math on the
loading per unit area of the cog splines on the aluminum cassette
body. aluminum's just not strong enough - as if that's not already
evident.
Not a radial shim... an axial shim.
