The thing is, if you live in a relatively flat area, then using an all-terrain gear is counter productive. Personally, when i use low gears and spin fast, i'm spinning out all the time. So what happens is, i have to wait to slow down to pedal again, else i'll be bouncing around in my saddle everywhere i go.
Fair enough, i can not do steep hills, but on the flip side, i go faster on the flats.
