The mountain bike wasn’t the result of a eureka moment by a brilliant inventor in his basement. It wasn’t developed by a research team at a big corporation. It wasn’t the brainchild of a marketing team. The mountain bike evolved from a group of people doing what they felt like doing. “We were just havin’ fun.” - Joe Breeze
In the mid 1970’s somebody in a group of friends including Joe Breeze, Otis Guy, Charlie Kelly, and Gary Fisher had the idea to ride their bikes down the rutted dirt fire roads on Mount Tamalpais in Marin County California. That proved to be a brilliant idea, but it was hard on equipment. They started raiding the local bike shops for pre World War II single speed junker bikes with stout frames and balloon tires that could stand up to combination of rough roads and speed. The 40 pound bikes became affectionately known as klunkers. Riding one was called klunking.
Before long the friends started racing downhill. More people joined them, and the events became known as the repack races. Riders would have to repack their hubs after every run because the combination of dirt and riding the coaster brake all the way down the mountains broke down the grease.
Unbeknownst to the Klunkers, 75 miles to the south in the hills around Cupertino, Russ Mahon and the Morrow Dirt Club were doing the same thing. The two groups briefly came in contact with each other at a cyclocross event in Mill Vally, CA in 1974. Klunker Gary Fisher was competing with his skinny tired road bike, but Russ Mahon entered with his klunker-like fat tired bike. Fisher was impressed that Mahon had added 10 speed gears allowing him to ride up hills and disk brakes with motorcycle levers to avoid the repack problem with coaster brakes.
After the Mill Valley event the Morrow Dirt Club disbanded when some of it’s members moved away, but in Marin county the evolution of mountain biking carried on. Gary Fisher returned home from Mill Valley and modified his 1930’s Schwinn Excelsior. Similar to Mahon’s bike, Fisher added multiple gears, thumb shifters, drum brakes, and motocross handle bars. They continued to improve components for durability, and in 1977 Joe Breeze welded up the first beefy frame specifically intended downhill racing.
Breeze’s client was Charlie Kelly, Gary Fisher’s roommate, who also coined the term “mountain bike” in 1979. That same year Gary Fisher, Charlie Kelly and Tom Ritchey formed a company called MountainBikes to manufacture and sell them. In 1983 that company dissolved, but that same year Specialized started selling the first mass produced mountain bikes, and Gary Fisher started Fisher Mountain Bikes which was acquired by Trek in 1993.
This is the trailer for Klunkerz - a documentary about the history of the mountain bike. It just came out this month.
