While most of your statement is correct, Trek does build their top two models in Waterloo, WI. The rest are designed here and made in Taiwan. The same holds true for most of the big companies you mentioned. They manufacture their top end bikes in their factory and outsource the rest of the bike. Up until a few years ago, the European bike makers were still making their bikes in their factories but now they are following the American trend. However, some of the Italian and other European makes, like Colnago, that still make steel bikes are still made in their respective factories.
