Everything is made in a few factories. But not really important
. Guy made reference to" Amerca" manufacturing. It's not a thing, hasn't been for decades. Treks are made in Taiwan. There is no team being supplied with US made bikes, don't, doesn't, has not existed for decades. If nationalism is your thing, bikes, bike racing is a hard pass,, if you dig down for product origins... You are going to be crushed.
Everything about bikes, bike racing is non national. All about commodities, whoever, wherever is cheapest.. Stories about carbon layups are folklore
