When I watch Quintana "the rouleur"on stages like this, I think about how he would fare much better in TTs if they had to do them on road bikes (obviously not going to happen). What I mean is he seems to get the least advantage from the TT bike of any top-tier guy. Now obviously that must have to do with him not dedicating enough time to that. But on the flats without the TT bike, he is small, looks very compact, but still produces lots of power (for his size). His success on days like today and Formigal (and Stage 2 of this Vuelta) are definitely due to his race-sense about being at the front at key junctures, but must also have something to do with be able to put out the watts on the flat so as to stay with these groups once he has made the split. Not that I know any of this for sure, just my observation from these past several years.
