I was watching some highlights from the Vuelta Stage 4 - which was one stage featuring both long flats and some substantial climbs... very dynamic. I tried to take a good look at the cranks of some riders while the camera focused on them, but it was hard to ascertain what set up most riders had running. That being said, I'm wondering - Do the Pros, on courses such as Stage 4, use compact cranksets? Or simply standard double gearing?
Does anyone race with compacts... and do well?
