I don't actually know. A friend met the manufacturer and checked out the hubs. He just said that they're beautiful. Since my hubs are flip-flops (I don't ride on a track ever, and sometimes a freewheel is nice), I've never thought to inquire.

I would note that their company "manifesto" includes the phrase "We work hard to build quality products at a price point that most cyclists can afford." So, perhaps they're not that expensive. who knows though.
