Chain Sprockets are effectively regular polygons. Because of this, when the small sprocket is pulling the chain a pulse is created in the system.
It is important not to choose a sprocket too small for the smoothest power transfer.
Most engineering manuals suggest that 17 teeth be a minimum for high speed systems.
This graph shows the % change in leverage as the sprocket rotates. (pitch /(2*TAN(PI()/ teeth ))) / (pitch /(2*SIN(PI()/ teeth )))
