a 13 tooth sprocket will give more torque and less speed than a 14tooth front front. and vise versa. a 41 tooth rear will give more torque and less speed than a 39 tooth rear, and vise versa. the smaller in front, the more torque and less speed. the bigger in back, the more torque and less speed. changing the front sprocket 1 tooth bigger or smaller is equilivent to changing the rear 3 teeth bigger or smaller.
