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.


This is what Easton have to say about it (after I got myself a pair of
Orion II's and asked them about 10sp issues) :

Carl,

Excellent information. You are correct that Shimano 9spd bodies
will have some "gouging" when running a 10spd cassette. We have see
this (not to the extent you are having with your Bontrager) in the past
but never so sever that it requires more that a light tap with a
plastic mallet to free the cassette. Lightly greasing the cassette body
will help reduce wear.

We do plan on making a 10spd only body but that is still a long way
off. The reason American classic make that "shim" is because they don't
have the "thick" splines on their shimano bodies. They try to save
weight by making each spline the same width as the index spline
(smallest spline), this makes it possible to tear all the way through
the American Classic body.

I hope this information helps. Please feel free to ask any more
question.

Holy crap! That would be one exciting sprint when that happened!


One vendor bagging another, I suspect it's something of an
overstatement

a shim won't do it - it doesn't bear the torque load.


A steel shim might. I'm going to see if it'll work on my bontrager
wheel before I risk it on my good wheels


Or just make a steel freehub body???

Why not try it on a set of wheels based around a shimano or Campag or
even DT hubset, instead of wheels outta boxes..like AC, Bontrager,
etc.....
