A life-risking bicycle manga! Ikegami Ryoichi's early masterpiece, which stood out in the golden age of Weekly Shonen Magazine in the 1970s, has been revived after 30 years! Keirin is a sublime sport that tests the athlete's outlook on life because it is so demanding that it fully utilizes all the muscles and motor nerves in the body. Orphan boy Todoroki Rin attends Yokohama Higashi High School thanks to the help of prefectural assemblyman Takahara. There, an unprecedented motorcycle vs. bicycle race awaits him! Rin hates the keirin that drove him to poverty, but his natural leg strength and destiny lead him to challenge the path to becoming the keirin king.
