  1. Im thinking of building a carbon fiber trials frame. I would like to
    know where people have had thier frames break other than the seat post.
    What where you doing when your frame broke?

    thanks

  2. The biggest stress on a unicycle frame is the side-to-side twisting you
    do whenever you pedal hard, especially if you're holding the front of
    the seat or a handle. The second biggest stress is probably shocks and
    pushes-pulls in the up and down direction, also from the front of the
    seat. Where that stresses the frame will depend on how much post is
    inside it...

  3. zoharj, you're gonna have to take into account the peripheral
    polypropylene extensive forces that exert a reverse spherical
    influential pull on the inside of the tubular K-Bend. Maybe put a
    waffle plate titanium alloy plate in there. let me know what you end up
    going with.

  7. ROLF!, I didn't even realize that was a joke! a Ti plate to reinforce it
    is actually a good idea though.
