Which riders have a path to a future Tour de France victory besides Vingegaard and Pogacar?
Bear in mind that these predictions will almost certainly be wrong. Because you all would have predicted Roglic would have the juice 3 years ago.
While Roglic was favourite in 2020 he also has a reputation of being accident prone prior to that Tour. So people half expect something will happen to him. Podium or crash no in-between. Like G Thomas of Ineos has the same reputation.
To beat Pogacar and Vinegegaard you have to be a very strong climber and TTer and even then that's not a given because of their physiological alien make up those 2 have. Basically you have to an alien yourself to really compete vs them.
As of today there are only 2 real contenders who can compete with those 2. Juan Ayuso who is Pogacar teammate. He can climb TT and is an engine. The other is Remco Evenepoel he isn't the climber of the other 3 (hes more Thomas and Wiggins ride to tempo and numbers) but has the biggest engine and best TT. As it stands Remco doesn't have the team to compete vs UAE or Jumbo.
Joao Almeida is another who has the climbing TT and engine profile but like Ayuso he's a teammate of Pogacar.
If you aren't an alien or have an engine who can TT and climb your chances of winning the Tour are slim.
