Off and on, Campy made half hearted efforts at covering the touring market. Their Grand Tourismo rear derailleur, for example, could theoretically handle practically any gear range.

Campy's Rally could handle wide ranges and actually worked. The Super Record could handle 50/36 x 14/26 (that's enough for almost everything but loaded touring).

As the Triomphe/Victory/Gran Sport proved, Campy could make competent touring equipment if they wanted to. Why they didn't is a mystery.
