Did some homework on the search engine and will have some good items to check out on the stand but I might have a couple good indicators that could help pinpoint the solution...
I have Record derailer/chain and running a new chorus (consumeable!) 11-25 on a rebuilt mavic hubset (read: zero hub bushing play/slop). I've been swapping wheelsets around and while I didn't have any ghosting on the last set (williams 30/same cassette), it has surfaced in spades on the Mavics.
Adjusted the derailer and noticed that it doesn't settle in the same spot if coming down to, say, the 16 tooth cog than when I come up to it (when coming down/outboard, the derailer settles farther outboard than when I come up from the 15 tooth). I noticed that the attach barrel for the derailer has a bit of 'slop' (i.e. I can grab the body of the derailer and it will ever so slightly rotate or wobble on the 5?mm attach screw to the hanger). Is this normal?
Set has low miles and chain specs as new. Getting an idea that if my derailer is settling at different points when going down vice going up, then I may have a cable restriction issue. Of note- when I rebuilt the mavic hub, the new hub bushing is a POS (sticks to rubber hub seal! Don't buy the rebuild kit from 'bay) and this resulted in one locked derailer (back pedaled, hub didn't move and the result was my bottom chain sucking the derailer into the lower chainstay...#$!%). Don't know if this incident has contributed to my current dilemma or not...hopefully not!
Appreciate your thoughts/comments/smart remarks.
