For reference, this bike has 420mm chainstays and the chain length is 112 links. Eagle-eye members will see a Shimano quick link in the first photo - this was done by a pro bike shop here in NYC (I had asked for them to install a Campy chain pin but this got lost in translation). I plan on correcting this.
Photos are taken with the chain shifted onto the small chainring.
Any thoughts would be most appreciated
Thanks!
For reference, here is my Chorus setup - 406mm chain stays, 108 link chain per Campag recommendation, 48-32 crankset, 11-29 cassette. Rear derailleur as it came out of the box (ie, I haven't touched the "B screw" - is there even a B screw?). Can confirm that, while the upper wheel looks awfully close to the sprocket in the first pic, it shifts cleanly and doesn't make any obvious noise (I don't use this small/small combination except when running through the gears on the stand). The crap all over the derailleur is wax flakes from the chain - it sheds bits everywhere when I run the freshly waxed chain through the gears - the wax is harmless, so I don't worry about it between bike washes.
Pix are (chainring/sprocket): small/small, small/large. large/large
