You also can add one sprocket to each side of the flange giving you a 2 speed. Use a spring loaded idler to take the slack out of the chain. This is something you would stop and move the chain by hand to switch the ratio. You also will need the 25 mm long socket head cap screws and maybe Five 6 mm flat washers used as spacers to keep the sprockets apart so the chain clears.
