I have a Dahon 6 speed Boardwalk. I believe it is the 4130 model as it says butted tubing but it really makes no difference. I am looking for a front axle for it. The one in it was bent and I have straightened it in my mini lathe but would really prefer to replace it if I can find one. The hub is an Access SA02 or SAO2 and is a loose bearing hub. Anyone one have details on this axle. Size, threading and where to buy one. Thank you for any help. Roger
