  12. wow, that broke when the pedal hit the ground. I wonder if pedal
    protectors could have prolonged the life of your frame.

    Perhaps it is time for a Triton? And a cheep Nimbus frame while you
    wait for the Triton.

    What is weird about that? Flatland puts alot fo stress on the frame.

    I'm not an expert but it looked like all he did was drop it? It snapped
    so easily!

  16. **My speculation bellow, feel free to correct me**
    This picture shows how all of his weight is on that crank and frame leg
    and he is trying to hold all that weight up by holding/pulling on the
    seat. It created enough pressure to slip out of his hand. Thats a lot
    of pressure on that one weld. Seeing as this a a pretty common flat
    move, you have to assume that the weld is stressed quite a bit. More
    so then with big drops which are usually landed on the pedals and
    cranks with very little weight on the frame. When there is its on the
    front of the seat (most times) so the seat and seatpost take alot of
    the stress before the frame. With flatland a lot of the stress is
    sideways, so there is nothing to take the edge off that stress. Its all
    goes to that weld at the crown.

    Aluminum is pretty weak where its been welded. ... what are ya gonna
    do?

    I am sure it was cracked before he dropped it, haha.

  17. Aluminum is plenty strong when it is welded properly BUT is does not
    take repeated stresses very well. That frame has probably been stressed
    many many times and the shock from the pedal hitting the ground just
    finished it off.

    This is why I would not buy a used aluminum frame.

    If you go frame by frame you can see it breaks when the pedal strikes
    the ground.

    $50?

  19. I dont think it had anything to do with the pedal hitting the ground,
    other than thats when the rest of the unicycle stopped and the top
    broken off seat tube kept going.

    Yes aluminum can be strong, when welded properly(which is considered an
    art). But even good aluminum welders are often times far from that
    artist status. Even a true artist can not keep aluminum from failing.
    There is a reason why Thomson posts are so strong.... anyone? ...No
    welds.

    It wasnt just that drop that did the everything. It took, what, 6 or 8
    months of riding to weaken it at that point, and all that combined is
    what allowed it to snap from that trick.

    Flatland, from the foot, body, and unicycle positions, puts tons of
    stress onto the frame. Way more than trials, and a bit more than street
    does.

    The KH frame isnt reinforced at that area either. And thats already
    been covered. I think the best frames would be the Qu-Ax steel or alum
    frame, the Triton frame, then the Nimbus II frame.
