Well, if the bikes are current year production bikes check the mfg. web site and see if it's supposed to come with a higher end group. If it is then the LBS switched components, or built the bike up (doubtful), because as was said, the clientele doesn't know the difference. The LBS owner can then either "upgrade" the bike for a nominal fee or sell the stuff on Ebay and maybe make a nice profit. I don't know for sure but if the bike should be production but isn't then there's something creative going on.

I know at the local Specialized shop by my house the dealer is free to swap parts on past years models. Whatever they have to do to move product. It's a volume game and I don't fault them one bit at doing what they have to do. I'd like them to be open when I need some tubes.
