Nathan Riddle



A professor at the United Bicycle Institute in Ashland, Oregon, Nathan has played an integral role in the landscape of American mountain biking. With a youth spent cross-country running, Nathan would find his true calling in 1996 upon discovering the world of mountain bike racing.

Nathan immediately immersed himself in the NORBAs, travelling in a converted school bus and racing DH, XC and dual slalom. He would later immerse himself in the Super D scene, the forerunner of enduro. Nathan still slays the races of his native North West, has reoccurring dreams of one-on-one combat with mountain lions and even has a tire named after him.
