The inaugural USA Pro Cycling Challenge kicked off on Monday with a stacked field composed of some of the biggest international teams and top talent in the sport. Despite the late slot in the calendar, even the Europe-based teams brought over most of their best equipment to tackle the high-altitude mountains of Colorado.
There wasn't much in the way of truly new equipment on tap in the team pits but there was still plenty of eye candy. Sit back and enjoy this image gallery of road and time trial bikes in use at this year's race.
