From Wikipedia...

Faliero Masi commenced making bicycle frames at the Velodromo Vigorelli in Milan in the 1950s, after a career as a professional racer and team mechanic. In 1973 his son Alberto took over the Vigorelli shop. Faliero and two assistants went to the US and began production at a new facility in Carlsbad, California after selling the "Cicli Masi" name and trademark to an American businessman, Roland Sahm.[1]

Many well-known and successful professional cyclists rode Masi bikes, such as Antonio Maspes,[5] Fausto Coppi,[6] Felice Gimondi, Jacques Anquetil [7] and Eddy Merckx.[8]
