This is something I rescued at Suntour before it went into the dumpster. Both the thing itself and the company.....

I've never been able to figure out if was an internal design exercise, or a submission from an inventor, or what? Looks vaguely Bivalent-ish, but the end of the bushing that fits into the freewheel has an eccentic inner surface. And the qr/skewer thingie's handle kinda looks like somebody just squished some tubing in a vise. The splined section on the drive side of the hub looks homebuilt and pressfit.

Normally this thread would make me want to dig it out and play with it, but I can't remember where it might be hiding these days.
