I do think Vingegaard will be the only one that'll be able to stay with Poggy on longer climbs whereas Roglic seems more likely to get dropped.Yeah. Pretty much everybody said Pogi is unbeatable. Vingegaard is the only one that can beat him. Nobody even mentioned Rogla.
Now lets see if that is reality or not.
But, on shorter climbs Vingegaard will lose (boni?)seconds. In the crosswinds he might lose time (same can be true for Poggy considering his team), but especially the cobbles will be the death of Vingegaard's GC ambitions.
Eventhough he has a good team, his 60 kg's will have him bouncing all over the place whereas Poggy will follow the likes of MVP, WVA, Kristoff and so on and he might end up gaining minutes on Vingegaard.
