Strangly, even though I have a Trek 4500 Disc, It looks like the Iguana is the better buy component wise. So as far as value, the Giant wins. But in the end, it matters a bit more how they ride for you. So for all I know the Trek may feel like the best bike ever, but the Giant might feel like junk, or vice-versa. If you like the way both ride, than the Giant seems to win this battle
