It is a Shimano Exage hub. I measured it and it is 130 on the spacing. I cold set my rear drop outs and all is good. I just recently stumbled across some info that says 6 and 7 speed road bike rear spacing is 126 and 7 speed mtb spacing is 130. But this hub was from a road bike. What am I missing here?
Exage was kind of a nebulous group -- some parts were clearly "road" or "mountain" but Exage oftentimes occupied a space somewhere in-between for hybrids or sport-touring or other not-premium bikes. I've had a couple of 130mm-spaced 7-speed Exage hubs pass through my hands. (I respaced them for my 126mm bikes.)

In other news, now that you've stretched out your bike to 130mm, there's nothing stopping you from moving up to 8-11 speed.
