Drivetrain Sprocket

One wheel on each side would presumably still be powered directly off the gearbox shaft, so that wheel would still need to be live axle. The others could potentially be switched to dead axle.

I'd like to emphasize I don't really endorse this design choice in general. I'd much rather just use smaller sprockets and be able to protect my chain inside my drive rails and above my bellypan. This is only if, for some reason that I cannot currently contemplate, a design bound you to using sprockets larger than the width of your drive rails AND bound you to a "west coast" style drivetrain.
