There isn't a bearing in the frame at the rear wheel, so the wheel is supported by the transmission bearings. A bearing could be put there though, and then the chain run on the inside. I've always thought it was a good idea not to run three bearings on the same shaft though.

I like the chain on the outside.
It makes it easy to get to the chain and it simplifies the ToughBox mounting since you don't have to make spacers between the frame and the gearbox.
I would estimate about 8 ft/sec. A 5" wheel on the toughbox gives about 9 ft/sec at the free speed of the CIMs, but there is going to be some frictional loss.
