I've been spending the last few months going back and forth between purchasing a specialized Stumpy and a Cannondale F600. During the last warm spell I had a chance to check out the Caldera and i was impressed. It's kind of a brick but the geometry was sweet, and I can get one for a bout 300 bones cheaper than the other 2--which the wife kind of digs. I'm kinda torn here, anybody with any advice???
