Im using campy hubs on my cyclocross bike that I want to convert to ss for the fall/winter. this is my first set of campagnolo wheels so forgive me if Im obtuse but looking around on the web it looks like the single cog kits like the kingkog from chris king only fit shimano freehubs. Im not sure if I want to break my cassette apart, is there anywhere that I can get a single campy cog?
