I have a set of 06 Ksyrium Elites with a Shimano freehub that I want to use for a Campy setup. I know there are conversion cassettes that allow you to use a Shimano wheel with a Campy drivetrain, but is it possible to change the freehub on the specific model that I have (Elite) so that I can use an actual Campy cassette?

Thanks in advance.
