They call them Gang Makers... why you ask? I don't know why but its pretty bad ass title if you ask me. Gang makers are the drivers who pace the racers in the Derney and Keirin events. They hit speeds over 45 mph and they're essentially the drafting partner for the each racer in a Derney race, and the entire field in a Keirin.
Here's a rare close up of these home made customized speed machines.
