The sprocket teeth are configured to protrude radially outwardly from the annular base portion. The sprocket teeth are arranged in a circumferential direction of the annular base portion. Each of the sprocket teeth has a tooth bottom defining a root circle of the sprocket teeth. The closed tooth opening is at least partly positioned radially outwardly from the root circle.
