After reading numerous posts about how one can use a 28T cog with a SR or NR derailleur, I decided to try it on my Mondonico with an NR. After numerous variations of chain length and wheel position in the dropout, I gave up and put on a higher capacity (not on topic) derailleur. Every step forward had a price. Perhaps Campy had accurate part ratings, and perhaps a good shop (are you referring to Assenmacher's?) has some more tricks, but I didn't see where they are. Anyway, it's back in riding condition, so I'm happy.

I did have some chain skip issues on 7-speed freewheels, but I think my chains have been too wide, and the derailleur feathering was too sensitive. Narrower (unmentionable!) chains have helped a lot.

Consult the masters! Go for a bike ride.

I hate to jump in here, not being the most mechanical guy on the list...I would say I'm somewhere near the 1475th least mechanical, in fact. However, if you are running a large cog with an older derailleur (say a 28 tooth with a Super Record) and your skipping is on the smallest cog it may just be that you have had to run so much chain on that larger cog that all you need to do is move your wheel more to the rear. Simple fix if it works...if one really wants to get into the more complex stuff like experimenting with grinding on the teeth on the freewheel I have an even simpler fix...this involves taking the dratted thing to my buddy's bike shop and letting his 40 years of experience come to the fore while I drink coffee and shoot the bull with the guys there...a lot less frustrating to me and often even cheaper than me getting in over my head. I sure am lucky to have such a resource! I realize that there are folks who really enjoy knotty mechanical problems...I sure am not among them. :^) Guys like Dennis Young (who pours his own Babbitt Bearings!) really fill me with awe.
