Channel Wasson is a USA Brompton dealer in Palo Alto, California. His website is
www.foldabike.com. I went to his home business about a year ago, and when the dust settled, I departed with a yellow and black T6 in my trunk.
Mr. Wasson had a personal Rohloff equipped Brompton, and he had extra Rohloff hubs and rear triangles that he had locally brazed with Rohloff specific dropouts. At that time, however, he was personally walking the path of the Schlumpf Swiss Mountain Drive convert after his journey to the mountain (Switzerland)!
I enjoyed interacting with Mr. Wasson. He is an upfront and straight ahead kind of guy.
