Good to see him improve. Last year really was a bit of a turnaround for him. Personally, i had my doubts after the immense hype and not really showing the same level in the following Vuelta or Giro. But he proved himself in a big way. I'm still not sure he's going to be a constant performer, and how he will cope with really hard stages leading up to a MTF (it seemed that most of his best performances, weren't on the hardest of stages). But his ceiling seems to be very high and the raw numbers were never an issue for him to begin with.
He seems lighter than 64kg, though he is 1m80, so not really small. But he's very skinny. I would assume the Strava data would be accurate if he wants to get the correct calculations based on weight. Unless he's trying to throw lurkers off.
