  1. I just realized (because my wheel builder pointed it out) that my N36
    frame seems to be bent. The left fork has about a cm more room between
    it and the tire than the right fork.
    No picture as of yet, but I know this is not from riding because i
    noticed it the day I got the unicycle, however, at the time it seemed
    like it wasn't the frame but the T7 that was mounted crooked.
    Now i realize i must have just failed to look at the horizontal
    clearance between the tire and fork.

    It doesn't seem to alter my riding.. does anyone else have a bent N36
    frame?

    And how come everyone keeps getting faulty items from UDC!? This is my
    second in one shipment!

  2. I thought that my frame was bent when I got it but it turned out to be a
    really crappy wheel build. Try putting the wheel on backwards and see
    if that changes the clearances at all. If it does your wheel is dished
    to the side but I am guessing this is not the case since you mentioned
    talking to your wheel builder.

    The Nimbus frame is really quite flimsy side to side and should be
    fairly easy to bend back.

  3. Yeah good call but its def not the dishing. He even mentioned that he
    tried to switch it around. I have also noticed the flex in the frame.
    How would you suggest bending it? Flat surface and standing on it?

    PS I will review Pete's drilled airfoil with pics in my RTL qualifier
    write up this weekend. But that's another reason I know the frame is
    bent. It has been like this for both builds.

  4. The frame manufacturing process has tolerances on the specs. The welding
    can alter the dimensions, even in a jig. There are many reasons why a
    frame is not exactly square.

    I find that the slightest side-to-side frame differences definitely
    alter the feel and the way a uni rides. Most will suggest shims in the
    bearing holders to compensate. But that can result in a wheel not being
    vertical.

    In this case, it sounds like the legs need to be re-bent, and, once
    properly aligned, the bearing holders need to be fine-tuned to be
    perpendicular to the axle.

    A padded vice and a good eye are sufficient tools. Don't know if this
    will help you, but if you want it fixed, manual bending is in order.
