The Stumpjumper was one of the earliest bona fide production mountain bikes —- a fact Specialized is trumpeting as the Stumpjumper turns 25 years old in 2006. The first two mass produced mountain bikes were sold in 1982: the Specialized Stumpjumper and Univega Alpina Pro. The word is actually "stumpjumper" instead of "stump jumper."
