I am in the market for a road bike and I was wondering if the carbon fiber fork is going to make a huge difference. I am not sure I can really tell that big of a difference actually riding it. I am currently looking at the Trek 1.1 (no carbon fork) and the Giant Defy 3 which has a carbon fork. The Trek is about 599 at my LBS and the Giant is 779. Both are equipped with pretty equal shimano equipment. What do you think?
