Of course I think this performance is very suspicious; as I've said several times. But I don't really see why we need to try to exaggerate it, by making claims that he has no TTing pedigree; when he's clearly shown excellent potential and performances in that area. Or by comparing him to a clearly below par Roglic and Dumoulin.
The man beat full alien Aru and Froome performances on the same climb in the 3rd week while matching Dumoulin on the rolling part of the TT. This is a 2007 Albi or 2013 Mont-Saint Michael off the scale level of performance, and he was not exactly a 2009 Cancellara on his previous TT performances.
