"Does the New UCI President Really Care About MTB?" Clearly not, and why would they? As rad as downhill is, it's a tiny fraction of road. More than a billion people watched Le Tour alone last year. If FIFA also ran the downhill World Cup on the side, how much would they care? None. None caring.
I think it's a good thing... Transition is also making their new bikes stronger/heavier. People are riding trail bikes harder because the geometry and suspension is allowing it.
The post-race photo of the Hannah siblings is one of the great downhill race pics of all time. It will get better with age, like Lemond after the '85 Paris Roubaix.
Gwin was also running the harder dual compound up front over the super soft 40a Aquila. I think that sort of compound is useful on super slick flat surfaces like slab rock and roots, but I would guess is damn squirmy on hardpack and under big g-forces.
