Schwinn? Schwinn has been chinese-made bikes since the 90's.
Trek makes most of its over $800 bikes in the US (so I've read) and Cannondale makes I think the majority of their bikes in the US. Beyond that I don't know of major manufacturers that make their bikes here.
Most bikes are made in taiwan or china.
