    Wow
    Looks like the wheel itself failed, never seen that before.

    If the wheel itself failed, can anyone say whether it was one of the new 6-spoked ones?

    If you look at the next pic they seem to be the six spoke wheels, they must have hit an impressive pothole to get that.

    @DeVos: you can get a pretty decent look at the hub <a href="http://cmubuggy.org/forum/v/2010-2011/2011-02-27/DSC_7864.JPG.html?g2_imageViewsIndex=1">here</a>

    Spirit buggy: Redefining catastrophic wheel failure with every roll...

    Anyone remember the picture from 2000 of the Spirit A driver holding the Ukai with all the spokes on one side snapped?

    We killed a few red 12-inch sbd wheels back in the mid 80s during spins. When you get sideways, and scrub speed quickly, the side loads are BIG. Huge on the leading wheel in this case. Much bigger than one would see in a non-sideways turn.

    Despite the extra spoke, these puppies look to be < durable than a xootr hub.

    busting up a wheel really isn't all that rare. spokers exploded with some regularity in thier day, mostly due to poor maintenance or wheel building. plastic SBD wheels got themselves banned for exploding. read lead sbd wheels could fail especially when 80% of the mass was removed by a rank amatuer with a jigsaw and lots of blades. that steel was freakin hard. I'm pretty sure one of our winning wheels in 85 was inverted and smashed flat against the bales in '84, then artfully beat back into shape with a ball peen hammer.

    we also destroyed one of beta's nice aluminum 12" race wheels in push practice with a head-on buggy collision, then flipped our buggy back over and finished practice without unloading.
