i bought my son (16) a new unicycle sometime back. he is quite an accomplised rider. he learned how an a cheapy i picked up at a garage sale. the new one was around 400 bucks. he also has a garaffe. never had a problem with the cheapy or the garaffe, but the trail cycle has a problem. one of the cranks keeps coming loose. have tried lock tite, but it doesn't hold for very long. any ideas out there will be appretiated.
