From Wikipedia, the free encyclopedia
Russ Mahon is an avid cyclist and founder of a cycling group known as The Morrow Dirt Club. Originally based in Cupertino, California, The Morrow Dirt Club were, arguably, the first to put multiple gears on pre-WWII balloon-tired bicycles for use off-road. These bicycles were the precursor to the modern mountain bike. Russ, along with Tom and Carter Cox, competed in a race in Mill Valley, California in 1974 on these bikes. It was there that Gary Fisher and Joe Breeze, among others, saw the bikes and developed them into the world-wide phenomenon known as mountain biking.
