Old man needs new bike. The daughter liked my road bike a lot. I haven't seen it lately. So I'm looking for a new one. I had a Giant Defy Alliance, it is a very confortable and fast bike. I've narrowed it down to the Giant Defy Advanced 2 or Specialized Roubaix Comp Rival. Anyone own these bikes or have some input on them. I know I really can't miss with the Giant, but before I pull the trigger, I'm wanting some knowledgable input.
