FYI - I was putzing around starting to assemble my 760 tonight. The Campagnolo Chorus RD stop screw doesn't contact the part of the dropout that normally limits rear derailleur movement. I though I had everything I needed, but evidently I'm a part short. Just giving you a heads-up, as this might possibly happen with your new 105 group also.
I was going to upgrade to a 10 speed group, so I'd need the thinner chainrings. Part of me wants to race on this bike, but I figure that's not going to happen so I might end up saving the money and just enjoying the bike. I do want to clean it up and make it look purdy though.
Thanks for the heads up though!
