Ok, get this...
I get home (and I should have done this yesterday) I held up the crank so it was flush with the bb shell. Even flush, the chain ring (when mounted outside the spider as it showed up in the box) is too far out to be perfectly in line with the rear sprocket on that i-motion hub. With the 115mm bb i bought today, it puts it wayyy out of line. So it looks like a 103mm is the one i need and even that won't give me a perfectly straight chain line.That rear sprocket is mounted pretty far in towards the center of the wheel... about perfectly in line with the edge of the bb shell. Well... back to the lbs for the exchange...
EDIT: Just did some actual measuring instead of eyeballing and it looks like the 103mm should be just about right.
