Proposal 29: Base 28/29" wheel size on rim size [ Revision 2 ]
Committee: Road RacingSubmitted on 2015-03-18
Status: Passed on April 01, 2015
Background
I am in favor of updating the Standard 28/29" definition for Road Races in the rulebook. Instead of basing it on the entirely arbitrary 768mm, we should instead base it on a very standard rim size of 700c rims (622 BSD).
Proposal
Old rule:
3.6.1 Wheel Size and Crank Arm Limit
• For a “Standard 29” Unicycle” the outside diameter of the tire may not be larger than 768mm and there is no minimum crank arm limit. No gearing may be used.
...
New Rule:
3.6.1 Wheel Size and Crank Arm Limit
• For a “Standard 700c Unicycle” the rim may not have a bead seat diameter (BSD) larger than 622mm (700c) and there is no minimum crank arm limit. No gearing may be used.
...
Also replace all references to a 29" unicycle to a 700c unicycle in chapter 3.
Body
I see several advantages here:
- 700c the standard rim size used in road cycling and is currently the rim size that everyone is using for their 28/29" unicycles.
- Riders can choose to use any tire they want without it being unfair. A rider can you a smaller tire which is lighter but doesn't travel as far per revolution, or they can use a bigger tire which goes farther but is heavier.
- We will never have a few rides build a custom 30" super light unicycle that still fits under the 768mm guideline. This is basically what has happened in track racing, and I think it's really silly.
- You don't have multiple definitions of the wheel size. (IUF says 768mm but the Düsseldorf marathon always had a different number.)
I don't see any reasons against this change.
