I think Brian has forgotten more about machining and fitting parts than you and I together ever knew, so I am not too worried about him having a problem.
Lets face it, a sprocket has a hole in the middle for a hub, a circle of bolt holes to hold it on, offset, thickness and pitch. I would feel guilty if I called someone who is trying to make a living, who I was not going to buy something from, to ask him a question when the answer is right in front of me if I use my own time.
I am absolutely sure that the pedal chain on the Bat is a standard bicycle chain. If I ever replace the chain on the Motobecane I will let you know.
I am considering a new drive chain for the Bat so I will let you know how that goes.
