campy Nuovo Record derailleur

Hello

At the risk of sounding like an idiot I need to ask you all a question, hopefully there is a simple answer. I am familiar with the high and low adjustments but I'm stumped with this screw/knob. So far the dr works fine so I haven't messed with it. Still I'd like to know what its for.

Hey, It's not an adjustment but a "stop" to prevent the derailleur from "flipping around". You can see the mark on the derailleur body where it makes contact. When you service the derailleur (i.e. take it apart and grease it) i think removing this "pin" or "screw/knob" allows you to put it back together easier as you have to reload the spring which is tensioned. I guess once you have it back together you can wind the spring around and replace the "screw/know". NR RDs are remarkably will made and they come apart and go together beautifully. I was amazed by the simplicity and robustness of design the first time I took one all apart after years of only dealing with shimano stuff which is way less service friendly if at all.

i agree. my thirty plus year old nr rear derailleur shifts as good today as it did new. i often think of it as finely made as a clockworks. nuovo record just possibly may have been campy's finest moment.

Thanks guys, not only for the info but also for letting me know that I have a great dr. I did turn the screw/pin a couple of turns but didn't notice any discernable difference or movement. I kind of suspected it might be some sort of stop but wasn't sure if it had another function also. Thanks once again, mystery solved.

I have the same derailluer on my 1969 Cinelli. It is a stop. I have on the north side of 50K miles on the bike and the only parts I have ever changed on the RD were the brass bushings. Today I ride my other bikes and this one is wall art until I ride with fellow vintage bike owners. The other parts on the bike are still perfect (cleaned and lubed the bike yearly). Friends are amazed when I roll past them down hill to a higher top speed with my old high flange ball and cup hubs. This includes the latest Dura Ace wheels.
