What's his best quality? He got a lot of top 5 places this year already. He's fast also, but didn't know he could do this on the Mur. How is he as a climber or TT'er?
He's pretty much a complete rider, except for one thing.
He climbs well, both steep punchy gradients and long climbs.
He's a very good TT rider (bronze at last years Danish Championships albeit without Vingegaard, Asgreen, Bjerg & Kragh competing).
He is fast enough on the line to hang with the fast puncheurs in a flat sprint, and beat them on a punchy uphill finish.
He's good on positioning and riding cross winds, and generally quite adept tactically.
However, which is the big unknown in terms of what kind of career he will get, he has appeared to struggle with recovery in stage races, where he tends to fade, even in some 1 week races.
He's still relatively green though and just 22, so that is an area he can possibly still improve upon (Vingegaard had those isuees at the same age as well).
TdF this year will be a big test for him, it's his second GT and the first one as a protected rider.
If it turns out he's not GT material, he will still be a candidate in the Ardennes, Strade, M-SR, Il Lombardia and hilly 1-week races in years to come.
As for Flanders, we don't know, I don't think he's ever been on cobbles.
