I actually am not even sure what brand/model of rims these are. They're the ones that Dahon put on the bicycle. I tried to change the title of this thread to reflect this but that attempt apparently failed.
ThorUSA says that their Dahon Speed 9 bicycles come with CNC machined rims. So people in the USA should order the bicycle directly from them, not from Dahon.
I'm off, to buy new wheels so that my new bicycle can properly function.
