I don't Know .... but based on @

Hmmmmm ..... who knows pros? Guessing has pretty much reached its limit I think.
I was watching a replay of the last monument race of the year and Phillipo Ganna flatted with his tubeless and had to stop and take a neutral service vehicle wheel rather than continue until the team car could get to him. Moments later, another rider flatted with his tubeless and it appeared one of the beads had come off the rear rim and he almost went down while trying to ride it. The commentator, Brian Smith I think, was saying "just stop! Please stop!" He did. Not being a star, the camera cut away and we didn't see how his situation played out. There was no mention of sealant. Of course, what went through my mind was "I thought tubeless wasn't supposed to flat??"
