• 1970’s in Northern California
• Forefathers: Tom Ritchey, Gary Fisher, and Keith Bontrager
• Idea was to create “Cycling’s Jeep”

• Proving Grounds were 3 mile long fire trails that descended over 1600 feet in altitude
• As races increased the popularity, rider’s abilities grew, and what was possible on a bicycle was pushed to the limit

• As riders tackled larger inclines, the requirement for more reliable brakes was realized.

• As riders gained the ability to more readily stop, they wished to start their descent at a higher altitude.
• This lead to the implementation of a Derailleur, a mechanism that shifts the chain to a different size gear, allowing better climbing ability.

• Modern parts essentially perform the same basic functions, but often with a lighter, and more efficient component.

• Mountain vs. Road
• Tires, Wheel Diameter, Fork, Gear Ratio, and even Frame Geometry differ

• Wildlife Disturbance
– Natural Buffer Zone
– “Direct Impact”

• Trampling
– Unintentional Plant Damage

• Erosion
– Less vegetation along trail leads to habitat destruction due to Mechanical Erosion

• Encourages a healthy lifestyle
• Increases Outdoor Advocacy by generating a Connection to Nature

• Further studies Evaluating Trail Characteristics and their monetary value to users.
• Refine erosion prevention
– “Pastry Club”
• Integrate information found to help with the design of construction of future trails worldwide.
