I came across this today while browsing Zipp's site. Zipp has released 25 and 28mm tubeless tires. I actually do think these could find a spot on my Zipp 30 Course rims for my CX bike during the summer. I did find a few things interesting in the marketing material:
"Zipp’s Tangente Speed RT25 and Tangente Speed RT28 tubeless tires deliver the lowest rolling resistance, best dry and best overall corning grip among major brands, according to testing at an independent lab."
"No tire levers needed or recommended for installation."
