Speaking of bikes we like or admire, I started looking at the details of the Dahon Mu Rohloff. Sure, there's the equipment: Rohloff 14-speed IGH, gates belt drive, Magura hydraulic disc brakes, Ergon grips, etc., but I notice the frame, while in the Mu family, is specific to this model. It's got screw adjusted sliding dropouts, and I believe it's the first production bike in the world to have internal frame routing of the Rohloff shift cables. It's hard to tell under the glossy 'Agate' paint, but it looks like Dahon spent more time and effort on smoothing/flaring the welds of this Mu's frame as well.
