It's close. The Jetstream post is about 11" total (I own one), the one on my Dahon Speed Duo is about 16", and the one is about 14.5". I'm shooting for 420mm, if I can locate it.

OK, I found this on eBay , but it's aftermarket.

Does anyone know where I can get a genuine Dahon Speed/Mu Uno handlepost? I'm looking for the best quality,...
