Thanks folks, makes sense, I guess the trick is to just be quick with the wrench, which isn't a big deal.
Another question from Mardmakarm's comment: why do you have to remove the tensioner? Wouldn't you be able to pull the chain off without removal once the wheel was off.
Or why would a IGH bike have a tensioner (I thought they ran one ring in the front, usually)?
