Teeth

can anyone advise me on the best way to reduce my gear ratio. i figure the cheapest way is to cut one from my 16t.

any suggestions on whether hack sawing is the way to go?

how many teeth on a 2nd hand sprocket?

mate, you must be the one messin' around, how on earth am i gunna ADD a tooth, there's no room.
besides, i want a higher ratio, so i need to take a tooth off
