With Dahon being such a bit player in the greater bike sales market and these bikes are mostly on line purchased we don't see many for service these days. So please explain the problems. Even better will be photos of the specific aspects for those of us who won't follow the text descriptions well.

Lots of us here could likely make a fork for a folder as long as any specific to that design elements can be fabricated or found already manufactured. Of course this would be rather expensive as making a fork needs all the skills of a frame build and perhaps more given the liability if done poorly. Andy
