So I took the Sirrus Sport, Cannondale Quick Disc 5 and Giant Escape 1 (all with disc brakes) for a quick spin today. I rode the Trek FX 2 and 4...they didn't have the 3 in stock. The only thing I am sure of is that I did not like the Cannondale. Just felt funny and shifting wasn't as smooth as the others. I think I like the Giant the best, but frankly it is pretty tough to distinguish. Would the Giant be a solid bike/decent value at $700? Thanks for all the help!
