Roller racing (think stationary bikes), pits two racers against each other while they race as hard as they can for about 20 seconds. A projector screen charts their blistering progress and lets the crowd cheer (or heckle) their favorite racers. Fast or slow, it's a blast for people of any skill level on a bike, and brings together commuters, racers, bike punks, fixie kids, and even the anti-hill, summer weather types.
