Pinot is pretty explosive, whereas Remco can't sprint to save his life. However, it seems very obvious to me that his CdA is much lower than Pinot's, based on their heights alone.But then what separates him from Pinot? Right now, I'd say it's that, first, he's more explosive.
It's surprising to me that their listed weights are so close when Pinot is 4" taller. We have no way of verifying Remco's weight, but I suspect it's lower than listed.about the same weight, maybe Pinot is slightly heavier
Although your conclusion is correct, I have to pick a nit here: power doesn't increase with mass. If it did, climbing wouldn't favor smaller (shorter) riders. Power clearly increases sublinearly with mass. And it's not as simple as "taller means better at time trialing", because most of the recent TT world champs are about 6' tall or just over. Even though it's easy to find humans who are substantially taller than that, none of them are very good at TTs.This is the key to why larger riders are generally better TTers than climbers--power increases with mass, or the cube of body height, whereas surface area increases only with the square.
