That's the old British SA you're talking about I think. The SRF3 and new AW types don't do that. I think it is a physical impossibility on the current ones, though the early Bromptons might have that problem. The new designs came in about the year 2000 when production and design moved to Taiwan. I've riddin a fair way on my SRF3 and never had any such tendency, however out of adjustment it has been. The worst result has been a kind of grinding sound as it tries to be in two gears at once. Nobody would continue to ride it like that unless they were mad, and even out of adjustment, a slight twitch on the twistgrip solves it temporarily until you can find time to make the required adjustment.



Lovely mods by the way Biekerouac, though my eyebrows did rise at the size of those scooter wheels. I got heal strike with small ones and took them off to avoid it. That brake noodle is a great idea.
