Campy doesn't make any cassette with large jumps, particularly 11 speed. They are all straight block up to the 17, at the minimum, then it goes 19-21-23-25-27 or 19-21-23-26-29 (when the 12-29 comes out).

Of course a 50/12 is about the same a 53/13, so if more top gear is needed, you can't have that too.
