There is a discussion going on in the German part of this forum, about the rules for the standard wheel setup at the Düsseldorf Unicycle Marathon.
I’d like to ask everybody who has already participated or who plans to participate in the future, to vote for the preferred setup rules.
Please do not vote if you are not interested in the marathon because I want to have a clear picture of the situation and “fun votes” would really spoil the poll.
[THREAD=91371]Here is the link to the poll[/THREAD].
Option 1: Stay with the current rules. Wheel diameter limited to 72.5 cm with a minimum crank lengh of 114 mm
Option 2: Adopt the IUF rules. Wheel diameter is limited to 76.8 cm (29") with no restrictions on the crank length.
Option 3: “Don’t know/not sure”
How permanent are the IUF rules for 29" class? I had the impression they were formulated specifically for Unicon16. That would imply that it wouldn’t make sense to try and enforce those rules onto other events.
Regardless, personally I like the “German standard class” as it is, so I’m gonna vote for that. I didn’t even know the max diameter was 72.5 cm, I thought the diameter was defined as 28 x 1.75" (Reifenprägung entscheidend). Anyone wanting to race a faster setup can revert to the Unlimited class, where everything is allowed in wheelsize, crank length and gears. So no-one has a reason to complain about ridiculous wheelsize or anything.
Hugo points to sections 2.2 and 2.20.13 of the IUF rulebook. I also point to section 22.214.171.124, where a maximum wheelsize of 750 mm is prescribed, not 768 mm as elsewhere. Moreover, in that section of the IUR rules, the 700c class is called a “special introductory category”. I think the IUF rules for 700c wheels are by no means final yet, and hence I think one should not change the Dusseldorf rules that have been in existence for so many years to something that is clearly preliminary.
28x1.75" is a crazy number to choose. It should be based on effective rim diameter (700c, 622mm) rather than nominal tire size, and if you’re going to base it on nominal tire size, why choose an odd size that no one uses?
A special introductory racing category for larger wheels. Riders may enter these races in addition to their regular track racing participation. The introductory races will be 100m and 1500m. Hosts may add additional 700c races.
• Tire diameter must be larger than 618mm (24”) but no larger than 75cm.
• No restrictions on crank length.
• Aside from this, 700c unicycles must comply with all other requirements for racing unicycles.
• Age groups for 700c events will be determined by the convention host, based on the number and age of participants.[/I]
I think this is a completely different thing. “The introductory races will be 100m and 1500m. Hosts may add additional 700c races.” This does not talk about marathon distance. But also here, there is no restriction on the crank length.
