    Using 9-Speed Cassette Wheels on a 10-Speed Cassette Road Bike

    Please forgive me if this question has been asked - I didn't see anything using search function......

    I'd like to use my flat-bar bike wheels between a new road-bike.

    I have an '03 Trek 7700FX w/Deore XT components and a 9 speed rear cassette.
    My bike came with Bontrager Select 700cm Paired spoke wheels. Being a bigger guy, I picked up a set of Mavic Open Pro wheels (700x?) that I interchange with my Bontrager's.
    I have put 700x23 through 700x35 size tires on both wheel-sets over the years without any problems.

    Now, I am looking at a new road or CX bike which both have a 10 speed rear cassette.
    Before I lay out $$$, I want to make sure I don't have to spring for a second set of wheels.

    I am assuming I can simply remove the 9 speed cassette from the Open Pros' and slide on the 10 speed cassette and put the wheels on the new road bike? or do the wheels vary due to the cassette width?

    Thanks in advance

    The present generation of Shimano-compatible freehubs are made for eight, nine and ten-speed cassettes.

    Ten-speed cassettes generally come with a spacer ring that goes on first. Less often, but more convenient, the largest cog will have a thicker area on the back in place of a spacer ring. I have cassettes of both designs.
    My two favorite things in life are libraries and bicycles. They both move people forward without wasting anything.

    There are 10speed hubs that will only take 10speed cassettes and I have a set of these wheels. You cannot retro fit a 9 speed on some of these 10 speed hubs.

    And Mavic Open Pro's are just the rim. They are normally used for home/custom wheel building and are not a complete wheel. The hub will be something different. But like tsl- I would say that a 9 speed freehub will take a 10speed cassette.- If it doesn't -----let us know.

    What hubs are on your Open Pros?

    The reason I ask is that recent FX models have 135mm rear spacing. I'd think that your '03 FX also has 135mm spacing. Conversely, almost all road and CX frames use 130mm spacing.

    If your wheels currently use road hubs with an extra 5mm spacer, you should be able to have the spacer removed and the wheel redished. If the wheel uses a MTB hub (eg., Deore XT) that can't be changed to 130mm, then I believe your current rear wheel would be incompatible with almost all of the carbon and aluminum road and CX frames available today.

    Yikes never even thought about the hubs.
    They are Shimano Ultegra FH 6600's. In fact, the only reason I bought these wheels were that they were on closeout and deeply discounted 3 years ago at Performance - Even cxheaper than the Fortes. I have been very, very pleased with them to say the least.

    Ultegra hubs laced to open pro rims are one of the best Training wheels you can build. These hubs will be 130mm spacing so should fit a CX or road frame.
