I have that same bike (2010 CAAD9-5) and love it. I have Williams System 30 wheels on it and went with a black saddle and black bar tape after the original white became, well, black. I like the red accents on yours - looks totally different than mine. I'll see if I can post pics.

How are you liking the 105 drivetrain? I have 6000 miles on mine and I'm done with it. It's had all of its tune-ups and cables replaced and I'm still not stoked about the shifting - especially the compact double front chainring. I throw my chain about every other ride if I am not careful moving from the large to small chainring.
