At the Amgen Tour of California , many of the world's very best teams assembled for the start of Wednesday's time trial in a hodge podge of rented vehicles, with follow vehicles ranging from wrapped team cars to pick-up trucks.
The actual cycling gear was mostly straight-forward professional grade, but there was still a fair amount of quirky solutions to be found.
BikeRadar wandered the team pits and loitered behind the starting house for a close look at all the riders' gear.
Suction cups, protruding camera booms, ice vests and plenty of electrical-tape and cardboard solutions were to be found.
