In 1997 the NBL joined USA Cycling, a sanctioning body that has long supported road race, mountain biking and other cycling disciplines in the United States, tracing its roots back to 1920. The resulting organization is the National Federated body that represents cycling in the United States. USA Cycling is part of the Union Cycliste Internationale (UCI) also known as UCI Cycling, the Switzerland-based international governing body that oversees virtually all aspects of cycling around the world (see International Sanctioning bodies below).
