out. I tried tightening it, and bought a new nut to see if it would work
better, but it still came loose. I finally sent it back to the vendor
(the Unicycle Factory), and Tom Miller put on a new crank, and I've no
problems since. Two things could have happened:
The crank arm wasn't tight enough, and it got damaged when loose, which is
why I couldn't tighten it enough.
The crank arm was off spec, and things were hopeless.
I don't know which was the case. Miller made it right, though.
To get to the point, you might try taking it back to the store and see what
they can do for you.
