Campagnolo Croce d'Aune lasted as a complete ensemble from 1988 until 1991. The defining rear derailleur with its external rod and complex mechanics was replaced by a slant parallelogram in 1991. By 1992 it was all over and CdA was absorbed into the Chorus group (abandoning its forgettable deltas for Chorus monoplanar calipers).
