If you're going to manually move the chain, then the SS chain will work, so long as the chain line for both chainrings is pretty good—1/8" chains weren't designed for a lot of sideways flex. Definitely try to get a 1/8" ring for an inner—stainless steel, of course. 1/8" chains don't play well with 3/32" alloy rings, and dumping the chain off the inside ring can result in frame/paint damage and a locked drivetrain. Get a Deda Elementi Dog Fang or something like it anyway. They're cheap insurance for less than half an ounce.
