I just received my new KH26 that I got on a crazy sale and I’m stoked. Got it all put together but still trying to decide on brakes. However I just noticed that the rim and tire spin perfectly smooth but are not centered in the frame. I would guess it is offset around a 1/4" - 5/16". I don’t think it will affect much but it did get me wondering if this is common and whether it is for sure the frame or if it could be the wheel build.
I tried to take a picture of it. Any thoughts? 
Look down the wheel and see if it has somehow been dished. Try and look straight down at the hub, and see if the tire/rim is actually offset to one side, but still straight in the frame.
If it looks straight and centered around your hub, then take your frame off, and place a sliver of pop (or beer) can in the bearing holder of the frame on the left leg according to the picture above. It might take 2 or 3 slivers, but it will shim your wheel back to center.
It seems to be a fairly common problem.
I had this problem with my nimbus oracle. Figures out that the top brackets weren’t fitting on the bearings. I had to pull one of the legs in just a wee bit to fit it correctly. Then it was centered. But if you’re frame is sitting perfectly on the bearings, it might be that the wheel is untrue.
First try installing it backwards to see if it’s the wheel, or the frame that’s suspect. If the offset moves to the other side it’s the wheel, if it stays on the same side it’s the frame.
If it’s the wheel I’d check that the bearings are fully seated on both sides first, and then re-dish (center the rim between bearings).
If it’s a bent frame it should be a warranty replacement, but there’s no good way to straighten it.
Hey thanks guys! I turned the wheel around and it moved the rim and tire to dead on center. I am guessing that since the rim didn’t move to the opposite side(mirror) that the frame must be out of true a fraction and the wheel is out as well.
This may be a stupid question but rather than trying to true the wheel couldn’t I just turn the hub 180 and swap the cranks and tire? I know that the pedals are directional but does the hub have a left and right? I can’t seem to visualize that.
Edit: I think I just found the answer
That is actually a very ingenious way to solve that problem. I’ve just shimmed my frame, but your method is much ‘cleaner’ in my mind.
I’m not sure about warranting a frame that’s only slightly bent like that. I think it’s a fairly common problem with a lot of frames.
I just did some dirty math and if the bearing housings(100mm) are welded on to the frame 1/16" out of true on a 26" wheel plus tire height. It will be out 1/4" at the tread.
You learn something new every day. I think I will flip the hub 
Thanks again
I think any manufacturer selling aluminum frames should replace one even if it’s only a little off. KH frames are supposed to be the height of unicycle equipment, and it doesn’t fair we’ll for them to keep second rate frames in the market. Steel frames can be straightened easily enough.
As for this particular one it’s possible that the wheel wasn’t fully set in the bearing holders the first time.
hm, If it’s straight when oriented one way, but 1/4" off when put on the other way around…I would rather shim/bend my frame and true my wheel to have no dish.
Since, if wheel is merely dished, but bearing mounts result in angled hub, then when the wheel is centered at the top(near the frame), it’d actually be angled…? (not centered if frame imaginarily extends to other side of the wheel)
if that much off, is there warranty??
There we have a nice piece of discussion where both sides are talking about the same thing in the same language and still don’t understand each other.
All in all one can say:
Uni hubs don’t have a left or right side.
There are left and right cranks that you
have to put on the left and right side of the uni.

I think it is probably fine, and there are no problems with the frame, or wheel. I have seen at least a couple of frames that had paint in the holders, and after the wheel was taken out the paint came out too. Result? Wheel went in straight. I think this may be what’s going on here. The likelihood of dish offset perfectly matching frame offset is pretty low.
On the other topics that have come up:
Seriously, how hard can it be to manufacture a straight uni frame? The jig would be far more simple than for a bike frame.
Shimming can be an option especially if it’s because on leg is longer than the other.
“No dish” is not what you want. What you mean is “correctly dished.” Wheel dish refers to the rim being centered between the locknuts, or bearings in the case of uni’s. With the exception of inboard disc wheels uni’s have symmetrical dishing. That just means that when the wheel is dished the spoke bracing angle on both sides is the same. Other wheels have asymmetric dishing meaning that when dished the spoke bracing angle is different on the two sides.
i see, thanks for the clarification!
One of my KH/wheel combinations was slightly off-centered. Turning the wheel around wasn’t an option because it has a Schlumpf hub and it would be odd to swap the shift directions. I used a very thin rubber shim to fix it.
If the frame is off the tiniest amount, and a bearing, and the wheel dish, and even some paint thickness, you might have a perfect storm that makes your wheel off-centered.
Glad you got it sorted.
I know all about the thrill of getting a new ride (I own five), but paying $600 for a new KH unicycle which isn’t straight is complete b******t, in my view.
I also believe that not sending it back immediately only encourages the manufacturers and retailers to keep sending out products with shoddy workmanship; it’s especially galling since the design/construction of a unicycle is so simple.
Obviously there’s almost no competition, so we can’t really take our money
elsewhere; I just wish the manufacturers and retailers cared more about their very tiny/very loyal customer base and took quality control issues seriously.
I have found that the tolerances on KH frames are tight, and you need to put quite a bit of pressure on the bearings to seat them properly. Once you do that you can back off a bit and they run true.
You may want to flip it back, clean out the bearing holders, and apply a bit more torque to see if the off-center conditions fixes itself.
This problem seems more likely than that the wheel dish happens to compensate for the error in the frame manufacturer when the wheel is flipped around.
