Nitto is a small family owned maunfacterer for Keirin racers. Keirin is a track racing circuit regulated by the Japanese government to the highest quality standards. Only the finest components from the finest manufacturers ever get the coveted NJS stamp approving them for use in Keirin events (Campagnolo's Record Pista group came short. They didn't get approval until the Keirin Pista group came out). Nitto is a Keirin approved component builder of stems, seatposts, and handlebars. Regardless of Keirin approval (some components cannot be approved because of materials/technologies/design), Nitto manufactures each one of their components with unmatched quality and attention to detail.
