Hi Kevin, I didn't respond, because I have never seen or heard of such a thing, as my understanding is (was) the same as yours. Figured someone more in the know would have chimed in on the subject. Have you closely compared the look and execution to other 144bcd era rings with pins, to see if it looks original or not? Of course, if it is original and from the 60s, it could very well look different than the method they landed on when the pins became commonplace in the 70s.

To: <classicrendezvous@bikelist.org> 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..........
