Specialized Bicycle Components Italian bike components that were difficult to find in the United States, but the company began to produce its own bike parts by 1976, starting with the Specialized Touring Tire. In 1981, the company introduced its first two bikes, the Sequoia, a sport-touring design and the Allez, a road bike. Specialized also introduced the first major production mountain bike in the world, the Stumpjumper, in 1981. Like the Sequoia and Allez, the Stumpjumper was designed by Tim Neenan and based on an early Tom Ritchey design. Specialized continues to produce bikes under the Stumpjumper name, including both hardtail and full-suspension
Trek Bicycle Corporation a few years Trek had outgrown its original "red barn" manufacturing facility—a former carpet warehouse. Recognizing the need for expansion, in 1980 Trek broke ground on a new corporate headquarters on the outskirts of Waterloo. Company co-founder Dick Burke would later recall that "it wasn’t until we built the new factory that we became a business." With more factory space available, Trek expanded its manufacturing to include complete bikes. In 1981 Trek entered the steel road racing bike market, introducing the "Pro" line, including the 750 and 950 models, and in 1983 Trek built its first mountain bike, the 850.
