You won't find much on this exact wheel. They were custom built for the show. The rims are made by Reynolds Composites as are the Vk51 rims.
They are kind of a niche brand of wheels. Couple guys set out to do something different. They are not mass produced like Zipp or Mavic, another reason you haven't heard much about them. They are more know in the small custom frame builder world.
