I bought a used Campy Titanium Cassette on ebay. The guy claimed 200 miles on this cassette. In fact it shows very little wear and works fine as long as the bike are on the stand. As soon as I ride on them, they skip no matter on which cog I am. I tried installing this cassette twice (two different mechnics) but the results were the same. Any idea what going on?
