Great ride. On Versus TV Cyclism yesterday, the second to last stage of the Giro d'Italia had a climb that was 20% stated as the most difficult of the race. The pros used 39/29 to climb it. It looked to me that they were spinning at rates similar to other climbs all be it with more pronounced body movement.
