Kevin,
I have two NR crank sets, one with, and the other without the "pip" I was told that this was a requirement when the distance between the ring and the crank was increased to accommodate the CSPC lip on the NR front derailleur.

Seems everyone is absorbed in the topic of 'spokes with a S on the head' to respond to my quirey regarding chain catchers on Campag outer chainwheels!.........or maybe I've got everybody stumped?
I know several of you have the older 151 bcd Campag chainsets..... looking resplendant on Bianchi's, Cinelli's and the like.........if you could just check your chainset to see if your's has the chain catching pip on the inside of the outer chainwheel........or have I got something unusual [there is always the possibility that someone went to the trouble of drilling, tapping and fitting such a pip.....but I think not] My other 151 bcd outer chainwheel on my Bianchi does not have the pip..........
