Yeah, I've wondered about that, too. I think CrossChecks are made in Taiwan rather than on the mainland. Hmmmm... anyone know who makes Surly's frames?
That said, I like Surly as a company and want to support it. If buying straight from the factory means Surly is left out of the equation, I wouldn't be so keen on this route.
I know there is a bike shop in Hong Kong that sells Surlys, but I've found the people there dismissive of questions and generally unhelpful.
