Rulebook

Proposal 36: Revise/Change 2B.1.2 Unicycles, 2B.1.3 Wheel Size Categories, 2B.6.8 Other Wheel Size Races and 2D.3 Communication [ Revision 2 ]

Committee: Track
Submitted on 2023-08-27
Status: Passed on September 27, 2023

Background

The rule 2B.6.7 (now 2B.6.8) Other Wheel Size Races is a bit strange because it describes primarily other wheel size categories and actually no other races. Therefore the question can arise, if the rule should rally be placed under "Racing Rules" and if it is really needed here. All in all the current Rulebook is not consistent about wheel sizes categories in many places, i.e. under 2B.2 (now 2B.1.2) it says "Only regular unicycles may be used" and regular unicycles are defined in 1D.1 to have no gears. But 2B.2 (now 2B.1.2) goes on with a table for unicycle classes that includes geared unicycles. Then 2B.5 (now 2B.1.3) lists wheel size categories for track racing but unlimited class is absent. All inn all 2B.2 and 2B.5 (now 2B.1.2 and 2B.1.3) should match and be consistent, so it was proposed to make a change here.

Proposal

Revision of the Rule: (As PDF Version with changes highlighted)

OLD Rules:

2B.1.2 Unicycles

1. Only regular unicycles may be used. Riders may use different unicycles for different racing events, as long as all comply with the rules for events in which they are entered.
2. For events divided by wheel size, there is a allowable tire diameter range and minimum crank arm length for each Unicycle Class:

[Table]

3. Any unicycles in question must be checked for compliance within their wheel class (wheel diameter, crank length and transmission), with the tire pressure that will be used in the race. Preferably, this check is carried out immediately before the race. Crank arm length is measured from the center of the wheel axle to the center of the pedal axle. Longer sizes may be used.
4. In all track racing events on regular unicycles, shoes must not be fixed to the pedals in any way (no click-in pedals, toe clips, tape, magnets or similar).

2B.1.3 Wheel Size Categories

1. Wheel sizes for track racing are 20 Class, 24 Class and 29 Class. Additional groups for 16 Class or other wheels can be added. When not otherwise specified, 24 Class is the maximum wheel size above age 10. For age groups with a maximum age of 10 or younger, the maximum wheel size is 20 Class (or smaller, if smaller sizes are also used).
2. The youngest age group for 24 Class wheels should have a minimum age of 0, so riders 10 and younger have the option of racing on 24 Class with those groups (e.g. 0-8 on 20 Class, 9-10 on 20 Class, 0-13 on 24 Class).
3. Unless otherwise specified, it is allowed to ride in any particular Class with a unicycle that fully conforms to a smaller Class (e.g. a 20 Class unicycle is allowed in a 24 Class race).

2B.6.7 Other Wheel Size Races

1. The host can choose to other additional track events based upon other wheel size requirements. Two examples include 700c racing and Unlimited. Exclusive of unicycle requirements, all other track racing rules apply.
1.1 In the 700c wheel category, unicycle wheels must be larger than 618mm in diameter, have a maximum bead seat diameter (BSD) of 622 mm, and there are no restrictions on crank length.
1.2 An unlimited race is one in which there are no unicycle size restrictions. Any size wheels, any length crank arms, giraffes or any types of unicycles (see definition in chapter 1D.1) are allowed.

2D.3 Communication

A Host is allowed to make helmets and/or knee pads mandatory for track races but it must be announced when registration is opened and must appear as an extra point to check for each discipline the competitor registers for.
If a large convention advertises events with the names of the ones detailed in this chapter, they must use the rules provided here. If hosts desire to do variations on these rules, the events must be labeled accordingly. Example: Track Coasting; Modified. In cases such as this, hosts must remember to provide detailed rules for these events at the same time the events are announced.

NEW Rules:

2B.1.2 Unicycles

1. Only regular unicycles may be used. Riders may use different unicycles for different track events, as long as all comply with the rules for events in which they are entered.
2. When not otherwise specified, 24 Class is the maximum Unicycle Class above age 10. For age groups with a maximum age of 10 or younger, the maximum Unicycle Class is 20 Class. It is allowed to ride in any particular Class with a unicycle that fully conforms to a smaller Class (e.g. a 20 Class unicycle is allowed in a 24 Class race).
3. The youngest age group for 24 Class wheels should have a minimum age of 0, so riders 10 and younger have the option of racing on 24 Class with those groups (e.g. 0-8 on 20 Class, 9-10 on 20 Class, 0-13 on 24 Class).
4. There is an allowable tire diameter range and minimum crank arm length for each Unicycle Class:

[Table] – only up to 24 Class!
Change: Diameter Range to "Outer Wheel Diameter"; delete "more than"

5. Any unicycles in question must be checked for compliance within their wheel class (wheel diameter, crank length and transmission), with the tire pressure that will be used in the race. Preferably, this check is carried out immediately before the race. Crank arm length is measured from the center of the wheel axle to the center of the pedal axle. Longer sizes may be used.
6. In all track racing events , shoes must not be fixed to the pedals in any way (no click-in pedals, toe clips, tape, magnets or similar).

~~2B.1.3 Wheel Size Categories~~ - this subsection will be deleted as it is fully integrated into 2B.1.2

~~2B.6.8 Other Wheel Size Races~~ - this subsection will be deleted as it is fully integrated into 2D.3

2D.3 Communication:

1. If a convention host advertises events for disciplines with the names of the ones detailed in this chapter, they must use the rules provided here. If hosts desire to do variations on these rules, for example by offering other unicycle classes or wheel sizes, the events must be labeled accordingly, i.e. "100m Unlimited" or "Track Coasting; Modified". The host can also offer events for additional disciplines. In both cases, the events for modified disciplines and the additional disciplines, they cannot be considered official IUF disciplines. In cases such as this, hosts must remember to provide detailed rules for these events at the same time the events are announced.
Note: Examples of modified discipline events would be Unlimited races, where races can be run on unicycles without any restrictions. An example of another wheel size category would be the 700c wheel category, where unicycle wheels must be greater than 618mm in diameter, have a maximum bead seat diameter (BSD) of 622 mm, and there are no restrictions on crank length.
2. A Host is allowed to make helmets and/or other safety equipment mandatory for the competition or individual disciplines but it must be announced when registration is opened and must appear as an extra point to check when the competitor registers.

In the linked PDF version hopefully all changes are highlighted: red and crossed out means this part is omitted, blue and italic is new, orange is moved.
In the proposal everything of the new rule which is new/changed is italic.
