Hi there! I´m an eager vintage biker and dont mind having my classic bikes on so called "exercise races, amateur races, gran fondos...". Theres no translation for the kind of organized races we got over here in Sweden, so what is a Century? What distance? Is it organized by the cycling authoritys? I do races between 150 and 300 km; is that century length? My two gems; A Crescent -79 all original and my upgraded Monark -75.
