Thanks for posting your experience.

That really stinks. I have not been a carbon person (for a lot of reasons), but I'm now starting to consider a tri bike in a few years (and once I feel like I've earned it). It will likely be carbon. I can guarantee it won't be Trek. That is not IMO an appropriate way to treat a customer (cause more damage to see if they will cover it). I would love to know what percent they actually decide to warranty....

FWIW I think you're making a wise decision. However, I hope that your LBS will share your dissatisfaction with trek and steer their customers towards other lines.
