Lynskey makes close to 10,000 frames a year, which is low for mass production but very high for hand-built frames. Given the nature of the U.S. economy and the extremely high cost of labor combined with very high costs for EPA compliance with industrial waste mitigation and disposal, I doubt there are many, if any, higher-volume manufacturers here in the states.

BCA puts out 10x that number of bikes per year, and they have an assembly plant in South Carolina, but the bikes they assemble are comprised of frames and components shipped from Asia.

So I guess it depends on what you define as "made."

I doubt it.
