    Does anyone know what would be required (or if it's possible) to use a 9sp Ultegra cassette on an
    older Shimano 600 7sp cassette hub? With 7sp spaced at 126mm and 9sp at 130mm, is it possible to
    just buy a 9sp cassette body to use with the 7sp hub? Is the 7sp hub 'wide' enough to support this?
    Also, would the wheel have to be re-dished? Would the 9sp cassette have enough room... ie would be
    the smallest cog be too close to the frame dropout?

    Please cc responses to [email protected], my mail reading doesn't always work. Thanks.

    You can use 8 cogs from a 9 speed cassette on the 7 speed freehub body, or you can replace the
    freehub body with an 8/9 speed freehub (keeping the original hub) in which case you should respace
    to 130mm and redish the wheel. The axle may be long enough to just add a 4mm spacer to the
    non-drive side.

    Oops, make that "the axle may be long enough" and forget adding the spacer. Must have been thinging
    of another problem.

    porbably just swap the freehub body for a 8/9s one-like first gen 8s Ultegra...

    Can onlyu get 8 of the 9 cogs onto the freehub with 9s spacers..
