Re: OY! Florida! OY! Sprockets!
nope. it doesn't change the ratio of the final gear.
there might be a sprocket or an application that will get a larger sprocket on a flip flop hub.
i don't have one so i never checked.
i know on my coaster brake hum i changed out my 20T for a 22t.
it gave a 10% more starting power but i cant "help" my engine when going by peddling.
you can get a shift kit. it brings the engine power to the other side of your tire and will let you use smaller sprockets because the way it is geared.
