After determining the number of teeth of the small sprocket and multiplying by the speed ratio, the number of teeth of the large sprocket can be determined. Generally speaking, the number of teeth of small sprocket is more than 17, 21 at high speed and 12 at low speed, but the number of teeth of large sprocket should not exceed 120. In addition, when the speed ratio is 1:1 or 2:1, please select the sprocket with large number of teeth as far as possible. Usually, set the speed ratio below 1:7, preferably around 1:5.
