I was lucky enough (right place, right time) to pick up a NOS set of those laced to Campy C-record hubs a few years ago. Haven't tried them out yet since I haven't found a special enough occasion...but I would think that they are fine for road use since the triangular cross-section of the rim is stronger than the usual box cross-section. Having said that, I think that mine were also intended for time trials since there was a SunTour Winner Pro 5 speed straight block on it.
