I remember back a few years Leif Valin saying he had modified a cassette hub to work like a freecoaster. Apparently you would back pedal and the pawls would disengage... I wonder if this is similar... Must have some sort of cam to disengage the pawls.
I love the look of this hub. About the size of a regular cassette hub. Hopefully it works well!
If anyone finds any more pics post them up! Pics of internals would be awesome too though not likely...
