I'm trying to locate a Dahon Mu Uno handlepost (or Speed Uno) to put on my Speed P8. The handlepost on my Speed Uno (Duo actually,...) is the perfect length for me, and the 2 bikes pretty much share the same handlepost. There's no flex, and I don't need adjustability. Any assistance would be greatly appreciated,...

PS: I've attempted to order a litepro & fnhon handlepost from a few different sellers online, and I've had no success.
