I've been shopping around for a new bike for quite awhile. And I have set aside a sum slightly in excess of $1000. As of right now I am looking at either a Trek 2.1, or a Giant Defy 1. Both are similarly equip, so the question comes down to the frame, obviously personal fit is the first question but I have test ridden each bike to a limited extent and find them both the be a good fit so far. I'm just wondering if anyone one has any experience with either of these bikes, or anyone has any opinion on which bike will be a better investment when I upgrade parts.
