Trek is one of the only bicycle companies that don't have weight limits on there frames. As far as not stiff enough the 2008 Madone's (5 and up) are probably right up there with the stiffest on the market. I think it sounds like cross chaining, but you would think any bike shop would know this, and one of their first suggestions would be not to do it.
