do you think that will be thick enough to hold out the polo crashes?
Somebody uses it?
thanks
Double butted spokes are also arguably the strongest.
?!? how is a spoke with less material stronger than a straight gauge spoke?
butted
non-butted (straight gauge)
If a bitch's 99Mph shot hits the top spoke, I'd be willing to bet it would break well before the bottom spoke.
An I-beam is stronger than a solid piece of steel. Just sayin'.
false equivalence is false.
x2. I-beam analogy doesn't really come into play here.
All he is saying is that in engineering applications, sometimes your intuition regarding the optimal solution is proven to be false, so you should present evidence to support your claim.
He's not saying that you should make your spokes out of I-beams.
Try to keep up.
Edit: 1 month late.
I'm no engineer, but I couldn't believe that the I-beam thing was true when I first heard it in the exact same way that I couldn't believe that straight gauged was weaker.
Jobst Brandt and Gerd Schraner have a lot to say about how wheels work and why, at least theoretically, double butted spokes are stronger than straight gauge. It all seems to hold true under conditions where spoke failure is from fatigue. In the real world where spokes fail from chains jumping into them, sticks getting caught or spectacular crashes, straight gauge seems to be stronger. In polo, bigger is better.
I'd suggest anyone interested in building wheels and how they actually work read Brandt and Schraner's books.
That's why I said "arguably"
if a "bitch" can even shoot the ball 99mph, I would think we have more to worry about than our spokes...
(edit) also, this is a good benefit of shields, keeping the "weaker" section of a double butted spoke from direct harm (i.e. shots, pedals, etc). that's also a major point to having 32h rims...having the shields to keep them at least a bit protected.
?!? how is a spoke with less material stronger than a straight gauge spoke?
Butts make the spoke more flexible, which increases strength by spreading the load over a larger area. Not sure in how it'll work in practice what with the bitches and all, but I'm still going to use them to build my next polo wheel.
EDIT: What everyone else said, more or less. x2 on wheel covers rocking out as usual.
debating over straight and DB spokes on a polo wheel is like comparing apples and oranges. I've been running DB spokes for one reason and one reason only. They are lighter. I've broke a fairly equal amount of straight and DB spokes. The variables that come into play with polo don't apply to the same as a wheel in the normal world, of say street riding or MTBing. In a normal cycling world, DB spokes are traditionally stronger though.
Thanks to everyone.
I am thinking about setting a wheel cover,to fortify the wheel,will be useful?
the thing about 32h wheels is that they still have gaps in the wheel that the spokes don't fill in... so the ball can pass through without a shield... but in a polo crash, there are too many variables to say whether a 32h would fail quickly. weight, speed, angle of crash, etc. (edit) generally speaking a 32h will probably fail compared to spoke counts higher, and will probably hold out a bit better compared to lower spoke counts....
since you ask if a 32h will be "thick enough to hold out", you should probably understand that spokes come in different thickness, as do rims. Triple walled rims, such as the velocity b43 or the rhyno lite from sun rims, are arguably the strongest. Double butted spokes are also arguably the strongest. I can't say if the julian is a triple wall, but it does have teh same profile as the b43.
I know a player here in Denver who has them and they seem to be quite strong.
there's a lot you need to understand about rims still friendo....especially polo rims...(edit) you should probably just search for the threads on rims beforehand...
