Cannondale's SuperSix frames are also USA made, according to their '09 press kit. I'm guessing that their other hi-mod carbon frames are as well, but they like to keep that information hard to find. Like the hi-mod Trek carbon, a considerably higher price range, but it's there.

I didn't know where Trek's frames came from, is all. For the '07 model year, all Cannondale's frames except the Synapse were said to be USA made.

I don't question the quality so much as the environmental regulation. Carbon fiber is an extremely toxic business.
