Specialized is an American bicycle brand founded in 1974 by Mike Sinyard in California. It first made a name for itself by importing Italian components before launching its own bike, the Stumpjumper, in 1981 - the very first mass-produced mountain bike. Specialized has become a world reference in mountain bikes, road bikes and cycling equipment. The brand has often innovated, notably with its carbon frames and Body Geometry technology. Today, it sponsors pro teams and remains a leader in the high-end bike market.
