Number-crumpling
 
I have read a few threads where people advocate crumpling/wrinkling up your race number prior to attaching it to your jersey. Allegedly the crumpling gives it more flexibility, allows you to get it nice and tight onto your jersey and reduces wind noise and such.

At a practice race yesterday, we got scolded for doing that, as it's apparently a rules violation (couple of years old rule?) and you can get DQ'd for crumpled numbers.

So, how are people handling this? Leave it uncrumpled and use more safety pins? Crumple anyway and risk being relegated? If you were a former crumpler-turned-uncrumpled racer, how have you handled the increase in apparent Fredosity levels in your own body? Or is it now that uncrumpled=cool and crumpled=Fred? It's hard to keep track of what's Fred and not these days...

Can you get practice DQ'd at a practice race??

Ooh, good one :rolleyes:

Again?? I say crumple away.

If it's a training series, I'm guessing they want to reuse the numbers. That's the only reason I can think of.

I use grizzy tape and never A) crumple my numbers and B) pin them. This stuff works great on jerseys but won't stick to a skin suit.

No. It's actually a rule. From the USCF Rulebook:

1K4. Racing numbers.
(a) Racing numbers are provided by the organizer, who may
require a deposit that shall be refunded on return of the
numbers in good order. The figures should be black, and be
12 to 14 cm high on a light colored background 20 cm or less
in height and 20 cm wide. The figures shall not be
handwritten, but printed in block letters using waterproof ink.
Numbers shall be constructed from materials sufficiently
durable to last the race without tearing or disintegrating,
even in adverse weather. The name of the race or race
sponsor may appear on a competitor's number. [Promoters
who fail to provide numbers meeting the above requirements
to all riders shall be fined as specified in the Schedule of
Fees.]
(b) Riders shall place their numbers as prescribed by the
officials and in such a way that they are visible when the rider
is in a racing position. Hip numbers shall be attached securely
at least at the four corners and no accessory may cover them.
If shoulder or frame numbers are provided, they too shall be
placed as prescribed. Numbers may not be folded, trimmed,
crumpled, or otherwise defaced
. [Replacement of the
numbers at riders' expense if noted before the start,
otherwise warning or relegation.]
The guy told us some refs are more sticklers about it than others and that he'd been warned. I suspect that didn't stop him from doing it again :) . There's no effect for us in the practice series (that is to say, no, we do not get "practice DQ's", as cute as that sounds), other than learning this stuff.

At one of the three crits I've entered I actually saw an official telling the riders to quit crumpling their numbers. Nobody was booted but the guy was obviously sick and tired of it. Apparently the idea is to be able to actually READ the number as you go flying by.

Gotta keep the material fresh, folks!

Number crumpling has to do with cameras and the judges eye. I don't know how many times we've stared at a monitor trying to figure out who the guy with the blue jersey was, 'cause his number looked like Montgomery Burns. Keep it pressed, clean, and in the perfect spot for viewing from the stage. If you are never in the results, then disregard my post.

Here in FL, we have a new rule for '07. We are going 25 deep in FPS races and 35 deep in Championship and Cup races. Might want to keep those numbers clean for us if you want in on that action!

Wow, if that actually gets enforced sometime I might just win one! :D

So, you're an admitted non-crumpler?

timmhaan 01-08-07 04:42 PM

i use 5 pins. 4 on the edges and 1 in the middle. the key is to insert the safety pins so that they're fairly flat with the jersey. that'll keep it nice and snug against the jersey and shouldn't 'parachute' in the wind at all.

I was until I gave in to peer pressure. :o

I tried that but it left residue, did you have that problem? The Grizzy tape left no residue.

bitingduck 01-08-07 05:21 PM

The kit I race in pretty much always has a number, and always in the same place, so it never bothered me.

I always wonder why teams don't design their kit with little markings where the numbers will go and don't put sponser names there (or discount the space).

And I race in a skinsuit a lot more often than I race in a jersey.

EdZ 01-08-07 05:25 PM

I usually do it, but I recently picked up a better practice when the South African national team was in town. They would fold the leading and trailing edge of their numbers underneath. Now instead of getting yelled at for illegible numbers you can get yelled at for hiding the names of the race sponsors. :)

this is what I did yesterday, and I didn't notice my number flapping about at all. I used one on each corner, and a 5th in the "leading" edge of the number. I also noticed that most folks had attached the number sort of under the armpit, so that's where I put mine.

DrPete 01-08-07 06:33 PM

I will be esctatic if I ever reach a level of racing where the aerodynamics of my race number make an appreciable difference. :D

The_Convert 01-08-07 06:39 PM

Crumple... they probably will never dq you and most done care at all.
Non-crumple is (still) very fred.
6 pins minimum.

platypus 01-08-07 06:41 PM

Oh noes! I am t3h fred for not crumpling my numb3r!!!

Ha ha, yeah, I think the aerodynamic gain of a crumpled number is roughly equivalent to that of a shaved leg, perhaps even less :D . But crumpling does seem to allow you to attach it to your jersey a little better (basically it's just making it more flexible), and that in turn seems to reduce flapping and wind noise quite a bit.

Hm Grizzly Tape eh... this stuff? Might have to try it! If it can hold the entire number down securely in a crit it must be darn strong.

'nother 01-08-07 07:05 PM

Hey toshi you were there in the mentoring when the other AV guy was saying that, right?
