They have a nice big drum which allows them to make the derailleur walk nicely across an 8-speed Campy Exa-Drive cassette freehub, in retrofriction mode. (I love Ergo shifting on the handlebars but I don't really see the value of indexing downtube shifters.) So, the other day, just to see what would happen, I yielded to temptation and, like a first-time visitor to Las Vegas nervously depositing a quarter into a slot machine, I moved the little dial to "7-index". And you know what? It indexed perfectly on that 8-speed cassette. Not just OK, but perfectly. (Sure, you get 7 gears indexed and the eighth goes beyond the detents and "indexes" against the limit screw, but it really does work.)

Fearing the risk of addiction, I quickly moved it back to friction and regained my virtue, but I still think, "My my my.... Whoo'd a thunk it?"
