I see RHD borrowed the idea from my post in the other topic. Cool. Came across the topic by chance.
Anyway, some names i've not seen mentioned yet, and deserved a shout, are Andreas Leknessund and Ilan Van Wilder. I think both will become outstanding riders in a few years. Both tempo climbers with a great ITT (both made the top 10 at the Euro's ITT for U23). Van Wilder was second best in the Juniors (and quite easily better than Evenepoel in their first year as junior... but ofcourse, Remco had only just started riding at the time). And he also made quite a splash when he came into the U23 as a first year espoir in 2019, winning the Queen's Stage in Course de la Paix and podium at l'Avenir, as well as a bunch of other 3rd-7th places in stage race GC. The only one where he finished outside the top 10 was Valle d'Aosta/Mont Blanc, where he finished 14th due to illness and a complete fckup by the organizer.
Leknessund is a year older, but was one of the most dominating forces in every GC he rode, overall probably the strongest in the races he entered, winning Course de la Paix and runner up in l'Isard. Both riders have signed for Sunweb, though Leknessund will turn pro at his old team first, before joining Sunweb in 2021. Also Thymen Arensman is one to watch (also joining Sunweb in July i think), but i feel he first first needs to confirm his amazing 2nd place at l'Avenir 2018, behind Pogacar. He's also still in college and focusing on his education... first. So difficult to tell. He's a skinny guy already, but very tall (i think he's over 1m90) so losing weight for him won't be so easy (compared to shrimps like Evenepoel and Van Wilder, who are both strong boys, at 1m71). He's had some bad luck in 2019 and never got around to showing his 2018 form.
I also can't remember the name of Thomas Pidcock being mentioned. Hyped as the heir to the CX throne for years, he's proving to become a very good CX rider, but at already 20 years old, he hasn't quite reached the level that van Aert or van der Poel had at that age. Not to fear, turns out little Tom is also quite the climber, winning Tour Alsace 2019, ahead of guys like Inkelaar, Valter, Verschaeve, Arensman, Kron, Champoussin... some of which were the better U23 GC riders. We also shouldn't forget, wee Thomas also packs some punch when it comes to time trialing, being the junior's world champ ITT in 2017 (the year before Remco). He also won Paris Roubaix for U23. I could see him become a contender in many different races. He can do cobbled classics, but his weight and size (he's tiny) might also help in hilly classics, and even the high mountains. Definitely one to watch. He's quite easily more versatile than van der Poel, but i fear he also might turn out to be a jack of all trades, master of none. We'll see.
Talking about CX, there is a kid who turned 17 last month, who's mopping the floor with the competition in his age bracket, winning 5 out of 5 world cup races so far. Goes by the name of Nys. His father also used to do some mild dominating in the sport.
I can't quite get behind Remco, because I just don't think he'll ever win a GT, which I think in the next decade will be dominated by South American climbers. MVDP will burn out, I'm afraid. I'd be surprised if he races 5-6 more years.
Strange statements. Remco has already made an impression, even without winning a GT. Even if he nevers wins one, there is still plenty of damage for him to do. He could win one week stage races, LBL, Lombardia, or become a De Gendt 2.0 turning into the ultimate stage hunter and become a dominant force as an ITT specialist.
I also don't know why all of a sudden South American climbers (plural) would start to dominate. Or are you talking about just Bernal, or just in the mountains? Or also about other riders as GT winners? They won't all be able to TT or survive windey planes.
And as long as van der Poel continues to have fun, he'll continue to race i think. His schedule is still neately balanced, so as long as they can keep it that way, i don't see a problem. Ofcourse, he turns 25 in a few weeks, so he'll be 30 before you know it but i don't know why he would be more susceptible to burning out.
