Pearl Izumi developed a cooling vest (co-developed with Allen Lim) with pockets to contain either ice or crystal-filled packets for the Garmin-Chipotle riders to keep them cool before the start of time trials. You probably saw this on the coverage. The idea is that it keeps the body core temperature cool while the rider gets the legs ready for the race. (Why did it take this long to have one of these?) Also seen are the new Campagnolo Super Record 11-speed and new Shimano Dura-Ace group.
