If they can fake a Rolex, right down to the details and engraving on the mechanism (and they do), faking bicycle components is no big deal. Easy stuff.
Our company produces cutting-edge waste-to-energy equipment. Dozens of patents. Huge, complex, expensive equipment -- our smallest machine requires a one-acre building to house it. And we could sell $10 million worth of equipment into China in a heartbeat -- just make a phone call. But we refuse all offers from China. Why? Because we know that, the minute our engineering drawings or a piece of equipment makes it into the country, there will be people at work duplicating our machines. And, at a minimum wage of $3 per day (which many companies violate by paying even less) and free of the kinds of labor, health care, safety and environmental regs that American companies have to deal with, they can produce stuff a whole lot cheaper than anyone else.
