Cycling requires a lot of skill. Ever seen Pidcock descend? How about the difference between Andy Schleck and Pogacar on the cobbles?
Also, didn't we have a thread on this board for many years called "Should triathletes be allowed on bikes?"
(Edit, sorry if the above comment was made in jest, sometimes my sarcasm meter blinks off.)
We have skill in cycling but it's not like Pidcock can win a GT just because he is 10 seconds faster on a descent.
The large majority of GT wins is conquered by a rider who dominates (or don't lose time) the mountain stages. Let's see the Tour:
2025 - Best climber won the race
2024 - same
2023 - same
2022 - same
2021 - same
2020 - same
2019 - same (mediocre time triallist)
2018 - same
2017 - same
2016 - same
In the last 10 years, the best climber (or close to be) won the Tour. Was Froome or Thomas very skillful? No.
Bernal? No. Pogacar? Above average but not MVP's level. Vingo the same.
To win a GT, a rider just needs to be average when we talk about skills.
But to win GTs, you can't be an average climber or even a good climber. You need to be close to the best at least. You need to be the rider who pushes the highest W/Kg on climbs.
