Looking for a road bike. I live in CO and I'm looking for something in Ti or carbon (but I'd go aluminum if I had to) to do group rides and training rides on. Looking to spend under $500 but could go higher for Ti or other high end frame. I'm thinking something like a Giant OCR Composite, a Litespeed/Merlin, Kestrel Talon, Soloist Team or Specialized Roubaix.
