I don't think so.Maybe they changed his cadence and/or pedaling technique due to this injury in spring… I hope he benefits from it
I think it's simply because it was so flat. I also think some of Rog'c critics should re-watch the Olympics TT, specifically the moment Asgreen caught up with Rog & overtook him on the descent & pulled away on the flat - owing simply to the physical differential (bigger = better on that part of the route).
Roglic is a climber & rouleur who excels on mountainous, hilly & rolling ITT's. Ganna was always going to smoke him today, as was WvA.
