    Where can I find one of these layback seatposts? In the BMX world I'm pretty sure this design is called a Zip style seatpost.


    I can find 7/8" ones on ebay, but they are not the required 1" size and the layback part doesn't look long enough. I think these were offered for new Whizzers at one time.

    Anyone know a source?

    When converting your new edition Whizzer to the "layback" seat post, it is wise to consider the stress. I know of several frames that had to be welded and re-enforced where the seat post connects to the frame. The Whizzers were sporting average weight riders [175 lbs to 225 lbs]

    Have fun,

    Yes, I read your prior warning. I am wondering if a beefier clamp might help distribute some of the stress?

    It breaks right in front of the seat down post. It crack across the large top frame tube [sam bar tank sits on.

    have fun,
