mmmm Roubaix.
+1 to what CJC said. Or buy one on craig's list - tons of people buy bikes and never really ride them.
In other news, you will likely have problems with the stock wheels. See if you can get the shop to RETENSION the wheels before you ride them and then AGAIN after you ride about 200-400 miles. Retensioning is basically the process of ensuring the spoke tension is as close as possible all around (both sides of the front wheel should be the same, but the drive side of the rear will be much higher by design).
When your stock wheels eventually wear out, just plan on replacing them. No big deal.
