Sam-
It's all the 2010-2014 era Chorus 11s stuff: shifters, chainset and deraillers
(white stickers, not red stickers, and no little boxed 'A' stamped on the parts)@edscoble (#8162) Other photos show current set-up. It's for a Look KG243, currently has a Veloce 10s groupset, with a 12-29 cassette. Photos show the space left when on big front ring and biggest (29t) rear sprocket. Distance c-c axle to derailler is 28-29mm.
Edit: I found a spare 105 11-30 cassette; the 29t Campag sprocket measures 118mm diameter at widest point (tooth to tooth), and the Shimano 30t sprocket measures 123mm at widest point, so only 2.5mm extra radius, seems small enough to be worth giving it a try.

Re. the Campagnolo Chorus 11 speed groupset cassette compatibility options...
My other other option is to use a an existing Shimano wheelset I have, with a new 11 speed Shimano cassette.
Assuming the Shimano 11 speed cassette works ok with the Chorus 11 speed set-up, two questions :
Shimano cassette with Campag set-up, is it better to use a Campag chain (which I understand are slightly thinner than 11s Shimano ones?) to suit the Campag set-up, or Shimano chain to suit the Shimano cassette ?
The spec for the Chorus RD says max 11-29. I wouldn't want to push to a 32, but Ultegra do an 11-30 cassette (and every little helps with the hills and mountains around here). Anyone tried this, or know if the spec is conservative enough to allow a tiny bit extra like this ?
Thanks.
