Masi Bicycles is a manufacturer of road, track, cyclocross and commuter bicycles based in Vista, California, United States. Historically, the Masi story began in the 1950s with Faliero Masi building bicycle frames at the Vigorelli Velodrome in Milan following his career as a racer and team mechanic. Masi then migrated to the US and set up shop in California. The Masi name is now owned by Haro Bikes. Masi have a strong racing pedigree and have been ridden by the likes of Eddy Merckx.
