Miches work fine, just not as crisp as campy.. I have bought some 14-23 miche so I could make some custom cassettes using the 18 and 20 cogs which I find I like quite a bit.. If you want real campy, good seller in san diego has Veloce's for 80.00.. I have bought a couple from him and is a good seller.. I like the veloces because they are all individual cogs so you can make your own custom cassettes and they are easier to clean..
