They told me they take it all apart and assemble it and tune the derailleurs. That's the "pro build" they normally charge $100 for.
I guess if somehow the derailleur got crushed on during shipping then it could mess things up.
I am going to ask if the LBS will price match to save some trouble though.
I'd forgo the $100 pro build from Jenson and save it for when you take it to your LBS after you receive the bike.
