A beautiful derailleur but performance is marginal, compared to even their French counterparts.
Amazing the time span Campy produced them. Even more amazing they weathered through the Shimano dominance and where the former leading Suntour had collapsed.
And virtually no US made derailleur set. Paul and someone else tried a limited run of rear derailleurs during the MTB hay day. Those purportedly not quite good.
