the Shimano 10sp/9sp alloy freehub problem again - a solution!
Our local American Classic rep came in to the LBS on Wednesday, and showed us some new lightweight clinchers, which in itself was of no particular interest. *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 : http://www.aboc.com.au/images/galler.../DSCF6994.html 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. |

I'm going to see if it'll work on my bontrager wheel before I risk it on my good wheels :) |

They're not very thick, but not foil. When I get some, I'll photograph them and put them up for you to see. |

Dear Bleve, Are these "shims" that you saw the "clips" shown in this pdf? http://www.amclassic.com/tech/pdf/10...psDura-Ace.pdf Cheers, Carl Fogel |

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. Adam Marriott Easton Sports Inc. |

That would be one exciting sprint when that happened! One vendor bagging another, I suspect it's something of an overstatement :) |
