the biggest frame builder in the world is in Taiwan and they make good frames according to the bike builders specifications. It's more frame geometry that you should be concerned with. if your gonna jump your bike or do serious "bombing" on your bike (as in professional racing) a Taiwan bike isn't the best choice. their matalurgical processes are less than American or certain other countries. The ultimate materials would surely come from the U.S.A., but your gonna pay for it. Even titanium bikes come in two different grades pushing a high end frame to around three thousand dollars. Otherwise a 6061 or 7000 series aluminum bike frame can cost about a grand. And then the components are gonna get expensive (who wants to put cheap components on a good frame) you could easily spend a thousand dollars on the drivetrain.
