As of 2021, the 2020 USA Rulebook Amendments is the most up-to-date set of rules that describe rules for North American Unicycling Competitions. The 2020 Rulebook Amendments cannot be used as an independent document; they must be used in conjunction with the 2019 IUF Rulebook. This document describes where the Unicycling Society of America chooses to differ from the IUF Rulebook for their competitions.
In particular, the rulebook outlines rules for the NAUCC.
