  1. I am working right now at a Unicycle Camp in California, alot of my
    students have the nimbus trials uni.

    The problem is that on the right hand crank the pedal is stripping the
    threads from the crank. All of these unicycles are less than 4 months
    old and have not been ridden hard at all. They all have qu-ax cranks on
    the uni.com cromo hub. It has crossed my mind that perhaps the pedals
    may have been cross threaded and that riding on them for a while may
    have caused the crank to strip out all the way.

    Is this a major problem for other people too?

    Is there a bunch of defective cranks out on the market that have been
    recalled?

    You can probably imagine that these students are very dissapointed in
    their new unicycles, I would like to try and help sort out the problem
    if it is possible, but I'm not sure that just putting re-tapping the
    crank will help. Should I contact unicycle dot com and see if they can
    do anything, or should I just tell my students to buy a new set of
    cranks.

    Thanks for your help guys

    No one said it was gonna be easy and I'm not afraid to try, with the
    odds stacked up against me I will have to fight, One Life One Wheel got
    to do it right. H2O

    unicycle dot com and they said they would send me replacment cranks.

  3. If the pedal has stripped the thread out of the crank 999,999 times out
    of a 1,000,000 the wheel has been put into the frame the wrong way
    round. So as you ride along the pedal can loosen and if you ride with a
    loose pedal it will strip the thread out of the crank.

    Aluminium cranks will strip faster than steel cranks because they are a
    softer metal so you need to be more careful about putting the wheel in
    the correct way round.

    To make it easier to see which way round to put the wheel in, both the
    cranks and pedals should be stamped with an R or an L to signify
    whether they should be on the right or lefthand side.

    If you explain this to your students hopefully they will stop
    destroying cranks, because if they buy new cranks and put them back on
    the wrong side again they will just strip the thread again.

  4. same thing happened to me, the right crank stripped when I was just
    starting a ride but I'd had it for about 8 or 9 months then.
