I've ridden both, both carbon. My view on the Trek was, nice frame and finish. Unfortunately, the chain-stays came away and the frame was replaced under warranty (a 1996 model). I now ride a Giant Carbon. This frame I really like. Unfortunately, on this one, the forks came away at the crown, luckily the whole thing was held together by the front-brake bolt and I managed to finish the stage I was riding, and change out the forks for the next stage !!
