Is there a trend of smaller guys/climbers improving their TTs relative to larger guys? Remco, Yateses, Vingeaard, Pidcock. Also, Alaphilipe, Rog and Pog
If so, what doping might explain. I think some people think that larger guys seemed to benefit more from EPO - Mig, LA - and from weight loss - Mig, LA, Froome, Wiggins. Might there be something that helps small guys more than big now? If so, what?
If not, what else might explain it?
It might be as simple as focussing on TTs. Small guys typically see themselves as climbers and larger guys as TT specialists, and so they focus on what they're good at from an early age and get good at that. So there are a lot of gains to be made by actually focussing on TTing. Perhaps Evenepoel's TT-ing has made smaller riders realise they can do more in this respect. Plus general increase in professionalism.
Also, smaller guys might be better at improving their position on the bike once they focus on it. (As relatively physically stronger, less prone to injury)
