I am confused...can anyone tell me what the difference (ratio wise) between my old set up and my new one: I started with 14 tooth front and 43 tooth rear. If I switch to a 15 tooth front and a 46 tooth rear will i be at roughly the same final drive ratio? How do you figure this stuff out? The reason for the switch is I am looking for more low end torque to the rear wheel while not losing the top end speed. Thanks for any help on this one! Scream.
