What do I need fixed?

The other day I went out for a muni ride and everywhere I rode my
unicycle was wobbly, I didn't know what it was until I stopped riding
and dropped my unicycle, when I dropped it I saw that the cranks were
nothing near parallel. I really enjoy muni riding so I'd like to get it
fixed, but I don't know what needs to be fixed.
Could anyone help me out. Here's a picture.

Edit, the cranks are square tapered, not isis

Looks like you've rounded off the squre part of the hub... so you'll
need a new hub and probably cranks.

either that or he's twisted the axle. Take off the cranks and check the
crank and ends of the hub, if they're rounded off then you need a new
hub and cranks, if they're not rounded then you'll just need a new hub.

no, thats probably bent. you'lll probably need a new wheelset, and if
you like muni , i would suggest a whole new unicycle (24")

a hub will be expensive to replace, i think you can find wheelsets for
$35-40, so that would be the cheapest option, just do a little
research.

I'm going to suggest hub + cranks replacement. But the truth is the
next guy is going to say for muni get a new rim and tyre. Then the
next guy will say frame and so on.... Upgrade, I don't think it is
worth it to stay w/ the torker.

So here's the deal:

If it's only the crank that is bent, and not the hub, then you need to
replace the crank and that won't be too expensive...

If the hub is bent, then it is probably not worth it to you to replace
that. You should just think about getting a new unicycle. It's cheaper
then upgrading piece by piece like that.

Forrest is on track. Check the cheap component first. The angular
displacement of the cranks in the photo is dramatic. You should be able
to take both cranks off and then put them on one side of the axle, one
crank at a time. You don't need to tighten them to do this. Don't allow
the axle to rotate when you do this. Look at each crank when it is
attached to the axle. If they look like they are at very different
angles, then AT LEAST ONE crank is CERTAINLY bent and you MAY have a
cheap fix. This does NOT indicate that the axle is OK.

If the cranks are bent, it is somewhat more difficult to check to see
if the axle is twisted or rounded because the cranks can't be used as a
reference. Try this. Anchor the wheel vertically with the axle flats on
top as horizontal as possible and the axis of the axle also horizontal.
It may already be obvious that the axle is twisted and you can't do this
on both sides. Balance a straight edge on one side and observe the angle
at which it rests. Now balance it on the other side and compare. For a
direct comparison, balance a straight edge on both sides
simultaneously. If the straight edges don't line up...



...buy a new unicycle.
