He generally does high rpm while climbing, but i've also seen that when he struggles, he keeps pushing a big gear for some reason.There have been multiple times when Remco seems to prefer a high gear where I think he would benefit from a lower gear. That struggle in Valancia was a prime example. He was basically pushing at stall torque for a while. Moving to lower gear would likely result in more overall power and as such a higher average speed, even if he can't react to accelerations of the mountain goats that much. He doesn't need to copy Froome or Armstrong but working a bit more with his cardio-engine would benefit him.
Not only did he start at Burgos and Poland, he also won them. Neither had a TT.I think it's good that Evenepoel also rides smaller stage races that should suit him a little less. Although he always chooses a stage race that includes a time trial. If the intention is to go for a win in Liege, then he should be very close to his top form in the Basque Country. If he does that for the overall victory, his career can still go in all directions. Is he failing again, or is he having a bad day, then we can gradually conclude that Evenepoel will not become a GC rider. Then he has to specialize in stage victories and in one-day races. Let's wait and see Itzulia. But also Liege, because it remains to be seen whether he will perform well there, in a major one-day classic.
Even if he fails at Itzulia, you could not conclude he could not become a GC rider. He finished 11th at TA and was 13th in the queen stage, well ahead of Kelderman, Hart, Lopez, Uran... He's only 22. When any other 22 year old finishes 11th in GC and has a great TT, people would be keeping an eye on him for future GC's. But because it's Evenepoel, finishing 11th should mean he should quit trying. lol
