Keirin is the spirit of Japanese professional cycling. Dating back to the 1940’s, Keirin began as a betting track race in which six to nine riders go head to head in a timed sprint. Like a horserace, each contender is assigned a number and a color; giving each race a unique color palate. in the Keirin tradition, DVS produced a line of convicts in 9 exclusive colors— mimicking those used on the tracks of Japan.
