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.

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 some of the gear in use at this year's race.
