I am thinking about putting together a bike for the fall and maybe giving it a go. I've got a ton of extra parts laying around from various roadie builds...Ultegra shifters, carbon this, aluminum that, but no frame. Always wanted to build up a CAAD. If I found a CAAD9 (or previous) frame in my size is it a good choice? Any others out there I should be looking for or keeping in mind. Mind you, I'm on a budget and I just want to test the waters before dropping a ton of money.
