This, he was also clearly the 2nd strongest behind Fuglsang in lbl on the climbs, short hills are great for him.I never looked at him this way but after checking his results I gotta admit there's some truth in your statement: he tends to struggle in hard mountain stages (although there are exceptions).
On the other hand his recovery (let's call it consistency if you wish) looks questionable too. He never managed to contend even in short and relatively easy short stage races like TA.
He's much better on hills than long climbs, that's for sure. Which brings us to the point I was trying to make: he's a good enough climber to make the cut on Sormano, Civiglio and so on. We're not talking about a multimountain Giro stage in the Dolomiti.
