After 10 years of experience of producing and refining the C-40, Ernesto Colnago introduces his all new C-50. The carbon fiber tubes are all new, with a larger, stiffer profiled center section to better absorb road shock. C-50 also features Colnago?s new carbon fiber rear triangle with B-Stay, a more rounded version of Colnago?s High Power chainstays and new rear dropouts. C-50?s new 1? 1/8 headtube is coupled with a new lighter version of Colnago?s Carbon Star fork. The Colnago C-50 is available in 18 sizes, including 4 sloping.
