Has anyone come across a hub that allows both fixed and freewheel? From the same side, not a flip flop but something that swaps roles? A mate who had a bike shop for many years reckons he has such a thing. It couldn't be found quickly in his mess and I was in a hurry. And he talks too much. He said it was something to do with Raleigh although I didn't get any more info. Won't see him for a bit so unlikely to se it in the flesh but I wondered if anyone here had heard of such a thing.
