Just changed my bike from 18 speeds to 8 speeds by dropping the largest and the smallest gears. Removed the de-railer and shifter too. I'll probably get a larger ring gear later to compensate for the lost top end. For now though, i'm using the middle gear. I had to cut the mounting hole ears out of the outer gear to use as spacers so I could use the same mounting location, and hardware. It works really smooth like, and won't even need a new chain stay.
