1979 Charlie Cunningham CCPROTO
Built in Fairfax, California from 6061 Aluminum “Cunningham, with a background in mechanical and aeronautical engineering, built his first mountain bike in 1979. He favored large-diameter aluminum tubing, steep angles, and low bottom brackets for stability. Fitted with wide rims, fat tires, and bars, the CCPROTO featured many innovations; purpose built forks, chainstay-mounted brakes, and wide-spaced hubs. Cunningham built just 178 frames before ending production in 1993.”
