USA Nationals

I’m planning to attend the USA Nationals in Salt Lake City in July with my five kids, aged 10-15, and have a few questions.

Will there be beginners categories?

What kind of unicycles should I bring? I’m thinking at least a few of them will want to race. Is there a standard type, crank length, wheel diam. etc?

We own mostly trials and muni rigs. Will we need others with plastic pedals etc.?

How about freestyle clinics? We’re excited but a little nervous about how we’ll fit in. Moab has been our only organized event thus far!


You should go to the Web site for the 2004 North American Unicycling Championships and Convention at to download the registration form. The registration form shows the events that will be run along with the age / skill categories available for each event. For more details on the age / skill categories and the events, you should follow the provided links to the USA, Inc.'s Competition Rule Book.


  • From the Competition Rule Book:

2.3 UNICYCLES FOR RACING (TRACK: Only standard unicycles may be used. A standard unicycle has only one wheel, is driven by crank arms directly attached to the axle, and is propelled only by human force. Riders may use any number of unicycles, as long as all fit within the applicable restrictions for events in which they are entered.

2.3.1 WHEEL SIZE: This is the maximum allowable tire diameter. Smaller sizes may be used. Some manufactured tires are marked with sizes larger than they actually are, but may be within the allowable size limit and vice versa.

For 24" wheels, the outside diameter of the tire may not be larger than 24.333" (61.8 cm).

For 20" wheels, the outside diameter of the tire may not be larger than 20.333" (51.6 cm).

For 16" wheels, the outside diameter of the tire may not be larger than 16.333" (41.5 cm).

If a tire is in question, or has no size marked by its manufacturer, its outside diameter must be accurately measured.

2.3.2 CRANK ARM LENGTH: This is the minimum allowable length, measured from the center of the wheel axle to the center of the pedal axle. Longer sizes may be used.

  • For 24” wheels, crank arms may be no shorter than 5” (125mm).

  • For 20” and 16” wheels, crank arms may be no shorter than 4½” (114mm).

  • For 16” wheels, crank arms may be no shorter than 100 mm (4”).

2.4 CLOTHING AND SAFETY EQUIPMENT: Riders are required to wear the clothing and equipment below for participation in all events of track and field, plus events that may be named elsewhere. This applies to all outdoor competition events, including Slow races, with no exceptions. The referee has final say on whether a rider’s safety equipment meets definitions. Starters will alert, or remove from the starting line, riders not properly equipped to compete, including riders with dangerously loose shoelaces. Riders completing events with insufficient equipment on will be disqualified. Though not mandatory in all events, helmets, elbow pads, shirts and other safety equipment are recommended.

2.4.1 BASIC SET: This applies to all track events, plus any other track or field event not requiring the full set below. The basic set consists of shoes, kneepads, and wristguards or gloves meeting the definitions in section 1.28.

2.4.2 FULL SET: This applies to all MUni, Trials, downhill racing (gliding), any event that goes backward at speed, plus events that may be named elsewhere. The full set consists of the basic set, with the additional requirement of a helmet. See definitions in section 1.28.

From Section 1.28:

FOOTWEAR FOR RACING: Shoes with full uppers are required. This means the shoe must cover the entire top of the foot. Sandals or thongs are not acceptable. Shoelaces must not dangle where they can catch in crank arms.

GLOVES: (For racing) Any glove with thick material covering the palms (Leather is acceptable, thin nylon is not). Gloves may be fingerless, such as bicycling gloves, provided the palm of the hand is completely covered. Wrist guards, such as those used with in-line skates, are an acceptable alternative to gloves.

HELMET: Helmets are recommended for all races, and are mandatory for some. Helmets must be of bicycle quality (or stronger), meeting ANSI, SNELL or ASTM standards for safety. No leather “hair nets” or helmets designed for low speed sports (football, hockey, etc.) are allowed.

KNEEPADS: (For racing) Any commercially made, thick version is acceptable, such as those used for basketball and volleyball, or any with hard plastic caps. Kneepads must cover the entire knee and stay on during racing. Long pants, ace bandages, patches on knees and band-aids are not acceptable.

  • Unicycles need to have non-metal pedals and non-marking tires if you wish to use them on the track or in any of the indoor venues.

  • We hope to have many different workshops / clinics. Please be sure to indicate your ideas on the spaces provided on the registration form.

May I suggest that you use the exact conversion factor (1" = 25.4 mm)
in your official rules. Am I nitpicking? The difference is more than
1.5% and that may be significant in the end result.
