Hmm, if I read this right I think you're referring to a system that Gabe Konrad pointed out in OTW and BikeLore. Seems to me Velocio was associated with it (don't have the OTW or BikeLore handy to verify).

> I've been searching the archives in vain for my favorite weirdness in which the chain goes through a convoluted wrap that engages both sprockets of a two speed freewheel enabling a forward pedal action for one speed , and a backward pedaling for the other, , both freewheels are always moving, one to

drive and the other in freewheel , I think it is a very old idea, and some list member has built one with great web pics , , I think this definitely needs to be on the list, someone help out, , , , , , regards, ,Tom Roberson
