What is the problem... Are there No USA made cranks sold at all? Or is the problem that are there no $75 USA made cranks?

The whole re-branding thing wont last. HTC (Taiwan) used to sub-contract for other manufacturers, but now makes their own, awesome phones. So don't despair: iust give them time and there will be Taiwan firm branded pedals, cranks, headsets, etc. They need time to own the technology
