I dunno, but Campagnolo seems to have had a sort of identity crisis right after the Victory group was issued. It was so much easier when it was just GS, NR and SR we had to deal with. After the Victory, Delta/C groups, there seems to be less of a signature look to the Campagnolo components that would have made it easier to identify which was which Didn't help that some of them had printed on logoes that wore off, specially at the cranks. I myself have a couple 90's Campagnolo components that I'm not quite sure what they really are even after doing all sorts of searches and posts on the net to try and pin them down. I was hopng to use them and start a first for me, Italian bike project, but the confusion and uber high pricing that comes with dealing with 90's Campagnolo components dampened my enthusiasm that they will most likely be sitting for a while till after a few more French projects uses up all my French stash. Maybe I'll just find/build up myself an easier to figure out full SR or NR group instead to start an 80's Italian bike project.....anyway, indexing,.....I never really had a need for them......
