View Full Version : Spoke Tension


Unicorn
February 25th 07, 06:57 AM
Does anyone know what the spoke tension is suposed to be for the
Following Wheels?

24" Alex DX32 with 13 Guage spokes.
KH24 2007 with 13 Guage spokes.
KH29 2005 with 13 Guage spokes.

Recently I brought the 24" Alex DX32 wheel into a well know bicycle
shop to be trued. The mechanic measure the spoke tension and was in
shock he said that the spokes had about twice as much tension as any
bycicle wheel that he ever worked on. Does this seem logical?

well uni wheels should have more tension than a bike wheel cause it
takes all of your weight as opposed to a bike wheel that takes half

That doesn't make sense. For a unicycle wheel you want it to be built
as strong as it can be with the components available, but the same is
true of a bike wheel.

i guarantee you theres more tension in the spokes of my trials uni than
any bike i own.

I couldn't with you more there iride. I also think the spokes of a
unicycle are more stronger than a bike for some reason. Cause in
comparison to a bike, wouldn't unicycle spokes have to be built to the
point of breaking because of people trying bunny hops and whatnot???

Yea, but none or your bikes are too crash hot. As Danny said, a rider
generally will want the strongest wheel build he/she can get with the
components they have no matter if its a bike or a uni.

Trials bikers and downhill mtber's probaly put a lot more pressure on
their wheel sets than we do. Either way bikers and unicyclists can both
use the same spokes and rims so the wheels we build cant be much
stronger than the other.

my bikes are alright, theyre not kmart material but there not worth

and generally unicycle spokes do have more tension than bicycle spokes.

I think because sometimes there are more spokes on a unicycle than a
MTB/BMX That's what i think. :D :D

If most unicycle wheels have double skinned rims then that would be a
relatively recent development, probably related to the rise of trials
unicycles in recent years. Bear in mind, though, that those rims were
made for *bike* wheels. What that means is that *bike* wheels often
have double skinned rims.

As it happens, all of my bike wheels have double skinned rims. None of
my unicycle wheels has a double skinned rim (I don't possess a trials
unicycle). There is no reason why a unicycle wheel should be any
stronger than a bike wheel, assuming the same (or equivalent)
components are used in its build.

I suspect that may say more about the build quality of your bike wheels
than about general differences between spoke tension for different
purposes?

Can I assume that your bike and unicycle wheels were not built by the
same person using matching components?

nope, they werent, but theyve been trued and tensioned by the same guy
at stages in their life.

i think we have to seperate between theory here and reality. in theory
yes they should be the same tension because of the components, in
reality, they are not the same tension, and that's just how it is.

In reality a wheel should be made to be as strong as possible with the
components you have. In theory wheels will have different components
and wheel builders so they wont always be the same. Therefore depending
on what components you use bike wheels can be stronger and uni wheels
can be stronger.

Thats true, but it probably has better components than my shark uni
did. An average bike and an average uni will probably have the same
tension as they would probably use similar components. A top of the
line bike will probably have around the same tension as a top of the
line uni, maybe more considering bikes have a lot more variety in their
components.

OK, in reality I've just been round all my machines and compared the
wheel tension. In reality the spokes on my 20" unicycle have
noticeably lower tension than those on the 20" front wheel of my
recumbent. The spokes on my 26" Muni have lower tension than those on
my 26" bike wheels.

There are two particular reasons for this. One is that I make a point
of tensioning my bike wheels a couple of times a year, while the
unicycle wheels might go two or three years between checks (I think I
last did the Muni about 18 months ago and the 20" about 8 years ago).
The other is that the bike wheels have better quality components,
allowing me to get the spokes tighter.

Assuming equivalent components, I would, in reality as well as in
theory, tension the spokes on bike and unicycle wheels by the same
amount.

(The Coker spokes have the lowest tension of the lot, natch).

I have 2 unis a trials uni and a cheap uni that i bought to learn on and
me and the rest of my family have about six good mountain bikes mine
being a fairly top of the range one, the spoke tention of the cheap one
was realy high and you could barly move them. my trials uni did have
loose spokes but it twanged realy badly so when we rebuilt the wheel
after breaking the hub we did them up to a tention that stopped them
twanging wich was not far off what my other uni was and they are now
alot higher than any of are bikes. i would of liked to of compared it
to my brothers trials bike but unfortionatly he has it with him at
university about 100 miles away i would guess though that his spoke
would be about the same tention as those on a uni as they need to take
a huge force, possibly more than a trials uni tire at times.
