But a FG/SS is both overgeared and undergeared at the same time depending whether your climbing or on level terrain. Your working harder in both instances. The only way you can replicate this on a geared bike is to stay in the same gear whether your climbing or on level ground. So what is the sense of having gears. Gears make riding easier which is what they're supposed to do.
