get some chain,jockey,sprocket noise goin up slight incline in saddle at 29/39 ( 10s) - anybody have any thoughts - don't get it at 21/39 - is there too little tolerance between jockey,chain,& sprocket at the extreme 29/39 combo ? campy design flaw when they went to 10s cluster ? and now there's an 11s - Shimano has a screw I believe that allows you to back of the rear deraileur -not so with Campy !

any experience or thoughts appreciated !!!!!!!!

Does your rear derailleur have 11t or 10t pulley wheels?
 
I know I need a medium size RD - it's Campy Chorus - how do I tell what I've got - would the pulley wheel tooth count tell me this ?

A picture will speak volumes.

A short Campy cage is 55mm long(pulley center to pulley center), while a medium Campy RD cage is 72.5mm long (pulley center to pulley center).
