How did I fail? The hub is designed so that the shift cable goes in only one side of the hub's axle. If you flip the hub around the other way like a traditional fixed/free flipflop hub, the designated hole for the shift cable/linkage would be on the wrong (non-drive) side of the bike and with nothing to attach the shift cable (which is still secured to the drive side chain stay) to the loose end would be flopping around as you rode.
