Fascinating. And, though he never mentions it, a really elegant argument for tubulars. Go to 18:00 on the video and look at his advantages for each, hooked and hookless. Tubulars have all of them. Any pressure that tire can handle. Rim simply isn't a factor. Road damage - as long as the rim is still a hoop, tire stays on. Yes, it does require a good glue or tape job, but we are talking a technology worked out completely 125 years ago. There is no flange that needs to stay more or less intact. No flange - easier and cheaper to make. Lighter. Much simpler from the molding, layup and QC angle. Virtually any tire can be run on any rim.

And yes, I know, such an observation is completely unacceptable here.
