Good thinking with the front dual disc brakes, personally I don't do front brakes on them for the clutch lever reason.
Well, I sent some pics, the hub pic shows that the hub has either 10-12G spoke holes, the one on the left is the one being sold, the one on the right is a 14G hub.
The hub has right handed threads on the right side, left handed (reverse) threads on the left side. The freewheel sprocket that comes with it is designed to be on the chain drive and it as well is left handed (reverse) threads. When it is mounted to the hub, spinning CCW torques the wheel and spinning CW ratchets the freewheel.
Now, the only way to put the sprocket on the right side with right handed threads, is to reverse the freewheel sprocket, putting the face of it away from the spokes. This changes the direction of the ratchet of the freewheel. There is only one configuration for the freewheel sprocket to go on the right side, and when it is put there the pedaling torque will cause it to click and ratchet. No matter what side of the freewheel you put the sprocket on, the ratchet is still only going to work in one direction, and the threads will only allow it to be screwed on in one direction.
This is because the drive chain freewheel sprocket is southpaw, such as when people do lefthanded pedaling setups. You would have to get a standard right handed freewheel to go on the right side of the hub.
But, if you were still wanting to get this axle I would be more than willing to sell it to you at a killer deal. Pm me if you want to talk about it.
I was looking at the clamshells, and while they look interesting, my hub is too skinny to accept it. As well, that would be a fixed sprocket, while I'm definitely wanting to take advantage of the freewheel on the drive side. It's really surprising how much a difference it makes. I know this only from pedaling the MxB after the drive chain snapped - it's NOTHING like pedaling with the clutch held, and the perk about the sprocket is that you won't have to clutch pedal ever again. When the pedal drive is torquing, the freewheel on the drive sprocket is engaged.
