So yeah my initial excitement as a noob is off a bit. I now get that a fixie sprocket would probably not handle well even with a lock nut. But, what if I added some kind of bearing sleeve between the lock nut and the inside stay axel plate? wouldn't that stop the nut and sprocket from going anywhere? It would have no where to go and wouldn't affect the outside axel nut? Couldn't you even use large washers as spacers?
