I wonder about the order in which they will rotate. Traditionally the small guys have been the worst TT'ers. But here it's almost the opposite with Evenepoel, Van Wilder and Alaphilippe. I would definitely put Van Wilder right behind Evenepoel, as he is the one with a similar build and aero profile, and good TT'er. If you put a big guy behind Evenepoel, he will only get minimal draft and tire himself more. But with Van Wilder and possibly Alaphilippe in between, the bigger guy following will get a bit more drafting. As i'm typing this, the selection is confirmed to be Serry as last piece of the puzzle.
I think it should be something like this: Evenepoel/Van Wilder/Alaphilippe>>>Cavagna/Serry>>>Vervaeke/Devenyns/Masnada
Serry behind Cavagna, and then Vervaeke and Devenyns behind them to get a good draft as i think they are the worst TT'ers. Van Wilder and Alaphilippe could also swap, both small enough and good enough not to suffer behind Evenepoel. Maybe put Masnada behind RE/IVW/JA could also work since he's a decent enough TT'er and a tad taller, so Cavagna gets a bit better draft still. But there are no real weak links (flakey climbers) in this team. I think they will kill it in the TTT.
