If low Crr really was a benefit, I think we would have seen it by now. But they have to build the air retention into the tire. And if they hold air better than a latex tube, then there is going to be a Crr hit from that.
I'm still waiting for a handmade fabric casing with the tread glued on (like a Vittoria or Veloflex "open tubular") with a coating of latex on the inside for air retention, and a tubeless bead. Could be the best of all worlds.
The Vittoria Corsa Speed says "Hello!" ;-)
edit: Besides, that tire is no lower Crr set up tubeless than if you put a latex tube inside it. So, where's the "theoretical advantage" of lower Crr?
