In addition to well developed thighs, keirin cyclists need to have powerful upper bodies.
While leg power is needed to move the bicycle, cyclists also need considerable upper body strength to control the handlebars. Upper bodies need to be as well developed as legs.
Keirin cyclists' thighs are extremely important since thigh diameter is equated with cyclist ability. Keirin cyclists take great pride in their thighs.
Uniforms and helmets are color coded to help identify each cyclist.
Keirin SS rank cyclists have special uniforms!
The color of the shorts worn by each keirin competitor indicates rank.
Keirin is a sport based solely on ability, with no consideration given to seniority. After completing keirin school, new graduates can register as competitors by passing a national qualification exam. All newly qualified keirin cyclists begin their careers with an A3 rank, and work their way toward the top rank by competing in events.
