Thanks Andrew There are indeed two ranges, and the "spread" between the two front chainrings is pretty wide right now. For the Gear Inch folks, what I have now is a 60 inch high and a 37 inch low in the 18T cog, and a 67 inch high and 41 inch low in the 16T cog. When I think of "hills" gearing I'd want the higher high AND the lower low. When I think of "flats" gearing then I'd want the two to be closer together, and indeed the flatter terrain is where a singlespeed makes a lot of sense.
Looking at the numbers I'm finding some appeal in running a totally stock and totally unwanted 53/39 crankset, matched with my 20/22 DOS ENO. The range of gears would be more in the 49 to 73 inch range, and bigger chainrings and cogs are known by the efficiency zealots to have less friction and lower chain tension. Plenty to play with, even on a two-speed...
