That sounds like a really good idea that I'd be interested in. Honestly, I am very uneducated about components of bikes, so I may have to do some research. Are 105 set components much better then what is on the stock CAAD8?
Thanks again for all the great advice.
Edit: Also, I've been looking at the Trek 1 series. I like the 1.2 and the 1.5. Both are aesthetically pleasing to me, and it appears that they try to at least use common component...
