I heard back from Sam Patterson... One of his testers has logged 5000 miles on the Metropolis using a fixed cog... but I was surprised to discover the Patterson Transmission actually freewheels; it doesn't engage like a typical fixie. He said you CAN ride it with a freewheel or fixed gear, but generally recommends a freewheel (I suppose to put the wear on the pawls of a less-expensive hub freewheel).
So for those looking for their multi-speed fixie fix, look elsewhere. Still, I'm really impressed with this crankset. BTW Sam Patterson was the inventor of the SRAM GripShifter (of which I remain a huge devotee), and he is still inventing new innovations for the cycling world... certainly a man to watch.
