Have any of you guys not seen the Sbarro hubless wheel? Here, let me fix that.
Expensive as all getout because of the giant bearings involved, and not as much weight savings as you'd think, they are totally impractical and yet almost hypnotically cool. It'd be so awesome to troll slowly down main street on that bike with a brace of trained poodles running alongside and hopping through your wheels. Especially if your wheels were on fire. And there was a midget in a clown suit yelling "Verboten!"
