    Do I need to adjust (bend) my cheap uni's frame to
    accomodate a Unicycle.com hub which is wider than the
    original? I had to gently pry the frame apart (~1cm) to get
    the hub to fit, and want to know how much the pressure is
    hurting the bearing.

    In case you're interested, this is on my 5 month old Sun
    which - now that the hub has broken - is down to only four
    original parts: the frame, seatpost, clamp, and tube. OK,
    five if you count the valve cap.

    Bend the frame so that, when you let go, it remains at the
    proper position to put no side pressure on the bearings. To
    do this, you have to bend it a little further than the new
    bearing spacing. Do the bending without the wheel installed.

    If you can, have a bike shop do the bending with
    frame/fork alignment tools. Otherwise, foot and hand work
    pretty well, especially for the lower quality frames that
    have softer metal.

    Roger Davies has a 'frame bending FAQ'
    (unicycle.uk.combend.asp). That FAQ will explain
    how to bend a frame so it will fit a wider hub.
