The Cunningham CC Proto is a mountain bike built by Charlie Cunningham in 1978-79 known for including many of the features seen in modern mountain bikes long before they were popularized. These innovations included oversized aluminum tubing, sloping top tubes, a single front chainring, a clutch derailleur, wide-range gearing, and "toggle linkage" brakes.^[1] ^[2] He also widened axle spacing and introduced grease-injection hubs to enhance durability and serviceability.^[3]

The CC Proto's unique dropped handlebars and high-rise stems influenced later mountain bike designs, while its tubular fork crown design paved the way for the widespread adoption of unicrown forks. Cunningham would later co-founded Wilderness Trail Bikes (WTB) to sell the components proven by the CC Proto.

The Cunningham CC Proto is currently on display in the Mountain Bike Hall of Fame at the Marin Museum of Bicycling.^[4]
