I was watching yesterday's giro and Formolo was going up the last climb in big-big. Of course the angle of the derailleur was a lot less extreme. Always wondered if using the two biggest cogs with the chain at an stupid angle is faster than using the small ring with the chain straight, pro cyclists seem to do it all time.
Guessing if he doesn't need another gear past that it'll be easier than shifting at the front then back again once he gets to the top, he probably knows what he's doing. Racing is a bit different than normal use and things like excessive wear don't really matter.
