    Shimano Dura Ace WH-7801 Wheelset

    Does anyone know if an American Classic or Wheels Manufacturing conversion cassette (for a Campy drivetrain) will work on these? They are 10 speed (as are the conversion cassettes).

    Thanks

    The 10-speed Dura Ace hubs and complete wheels have aluminum freehub bodies with taller splines than the former 8/9-speed freehubs since the bodies need the extra area to avoid notching by the cogs. They will only accept 10-speed Shimano cassettes. I don't know if the AC or Wheels Manufacturing conversion cassettes have the deeper splines needed to match these hubs but I don't think they do.

    How about using a 10-speed Shimano cassette and a Jtek shiftmate to make your Campy brifters and RD work with the Shimano cassette?
