Mark, you have the concept of the wheels correct. I watched Pino cut up a set of wheels just like those once when he was mad. The spokes were titanium and he gave them to Jim Reese, to use as welding rod. He was upset about his design got gaining commercial acceptance and told me "If they're not going to pay, no one will get them!" Then grabbed my diagonal cutters and destroyed the wheels.... This was again at Kinetics back in the '80's
Mark, I have to wonder if we've ever met?
