 Its new frames were based on the Koga Miyata frame on which Peter Winnen won the Alpe d'Huez stage of the 1981 Tour de France.Each custom-ordered frame was to be hand-built and made with Miyata's traditional chromoly steel process, featuring Campagnolo components, at its Chigasaki factory.Although demand for Miyata unicycles outside Japan has diminished in recent years due to a wider range of quality unicycles becoming available, Miyatas were once considered to be a highly desirable unicycle because of their quality of manufacturing and well designed saddle during times when choice was often limited to expensive custom-made unicycles or extremely poor quality products sold in department stores.
