Or like Sachs or Sun Tour Ultra or the majority of 7 speed freewheels. If you are a Campy fan, and also of the opinion that all you need is 7 gears (even if you do mountain riding), but you want an indexed (non friction) system, merge Campy's early 8 speed ergo levers (or even later 8 speed ergos with the group name on the lever) with a Campy 7 speed drive train and employ the flexibilty of Sachs or SunRace or Shimano 7 speed freewheels which might provide anything from a 12-19 rear cassette to a 13-32. You will have one gear on the levers that doesn't do anything, but you will have a solid 7 speed system with the flexibilty to have the cog range you need in the back rather than be limited by Campy's 8-speed offerings (or 9-speed for that matter).
