I have a single speed, the main sprocket is 44 tooth and the wheel sprocket is 18 tooth. It is pretty difficult to pedal, most of the time I have to stand up to get going. I want a pedal gear that is very easy to pedal, and the largest wheel sprocket I can find is 22 tooth, only 4 teeth bigger (bigger sprocket = easier to pedal ya?) Would the extra 4 teeth make a big difference or not so much?
