I've never seen one that didn't have problems; either broken completely, cracked, etc. One of the dumbest ideas ever IMO. But there are defiinitely bikes out there that were designed for these posts.
Maybe Grand Bois will see this thread and post pics of the post he made from a regular post. I remember being impressed by it.
The way this one is designed varies from the angled plug I see on quill stems. On this one, the plug is a round taper and expands a split sleeve against the tapered end of the post such that the sleeve expands evenly. It came out dry, so I need to grease it up and put it back.
