obviously wheel aerodynamics are much more complicated than frontal area. obviously nobody runs 20mm tires anymore...
Yes it is, but generally if you have the same shaped object but that object's frontal area increases then so does its drag. Track bikes use 20mm tyres. Another example of where aerodynamics and rolling resistance are very important but since they're not worried about pinch flats, they don't need to widen tyres. Do you see any track teams running 30mm tyres? No, of course not, because they'd be slower. Wider tyres are used to deal with 'terrain' and wider wheels are more aero than skinny wheels with wider tyres, not simply because wider is more aero.
What isn't right about Crr? "Even if you did run them at the adjusted-for-comfort pressure, as you say, the Crr is basically the same, so no advantage in going wider" is literally what you said and everything else I wrote is lifted from the article you linked to.
Maybe. Or maybe he wouldn't have even made it to that point in the race on tubeless.
Slowing down one-handed with a flat front tyre is not the best way to remain upright no matter what your choice of tyre is. When the peloton is racing on tubeless tyres, maybe then I'll believe the hype.

I'm not saying you're wrong about all this - but isn't this a poor metric? Pros will by and large race what they are told to, no?

yea ofc. not disagreeing with bigger is less aero all else equal. i just think it is a relatively small difference outweighed by what it buys you.
maybe i misunderstood you. i was merely disagreeing with the notion that wider means more crr. the advantage is not bottoming out, better traction, less risk of flatting. but you already know all of that.
and sure. we can rehash this in a few years then :D. someone ran the 30mm tubeless s-one at roubaix a few years ago didn't they?

oh are they? you said they were 29mm rims. if that is the case then my point isi more invalid.

and no that isn't right about crr. the link i put in my last post shows this with the gp5000. if you inflate to the same tire drop, or casing tension, and the tires are made of the same compound, the crr is the same.
yea maybe mvdp wouldn't have pinch flatted in the first place, or maybe he'd of retained a more rideable pressure.
i watched the footage a few times and couldn't see really what took him down, and different news outlets have all said different things. his wheel was not in line with his bars when he hit the ground though, so idk what is going on.
