So you mean the good/not so good things about it? I own one and have
nothing but good to say. It's very stable and robust due to 48 spokes.
Maybe the wheel set isn't the most strongest one, but it can easily
take up to 1.70m drops at least. I weigh 65 kg. And I'm also sure
that's not the limit. I'd say go for it. It's worth the money! :) Only
little downside might be the weight (6.4kg officially) but mine is more
like 6.1kg... Though it doesn't matter that much, the weight I mean.

I've got the splined yellow hub on my 24" Muni & I havent had any
problems with it... it's very sturdy/solid.
I weigh 72kg and have done many 1 meter still drops without riding out
and it hasn't hurt it at all. (I'm still too chicken to try any higher)

Hi,

I have been riding a qu-ax trial for 8 months now and i am really
satisfied of it.

The only problem is the Q factor of the cranks. It's harder to do all
the moves that involve your weight on the crank/hub. And without
protections for my ankles, i hurt them on this part. These problems
don't exist on a koxx-one devil (there are others...).

I broke the saddle and seat post twice on some bad landed crankflips
and unispins over sets. And one of my pedals has exploted whereas the
other have no pin anymore. But i think this is the normal evolution
which obviously depend on the way you ride.

It's quite cheap for a splined hub so you can save money for the future
parts replacements.

Now it comes with a new extra wide rim, i freaked out when i saw it.

"problem" with Q factor?? IS there a Q factor or are the cranks
straight, like torker?

You are totally right, but a part of the hub go 1cm out off the hub.
The possibility of contact to the ankle is then increased. And as these
ankle biters are quite sharp (when you apply great stress) the
possibility of injury is increased to.
So again you are right the q-factor itself is not the problem for the
ankles injury thing. It's only the shape of the cranks that's not
perfect. The koxx Isis cranks are flat for example.

Nevertheless if you want to do tricks with all your weight on this part
of the uni like Xavier does (
http://unicyclist.com/forums/showthread.php?t=46812 ), it's better to
have space to put your foot on. Generally if there is a q-factor, this
space is reduced and it's far more difficult (i only have tried koxx
and qu-ax cranks though).

But whatever, the qu-ax is worther its price than the devil, especially
if you only start to go big. (Is my sentence right ?)


And i don't know for the rim, i saw one on a uni bought 4 months ago.

Q-factor is the distance between the pedals; all hub/crank/pedal setups
have Q-factor. If the cranks are straight, the Q-factor tends to be
less, but the hub width also plays a role.
