oh are they? you said they were 29mm rims. if that is the case then my point isi more invalid.
obviously wheel aerodynamics are much more complicated than frontal area. obviously nobody runs 20mm tires anymore...
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.
