When cycling the cyclist experiences a aerodynamic drag force which is the most important resistive force.The drag force can be calculated by knowing the density,frontal area,velocity,and the drag coefficient.The formula for calculating drag force is given by, Drag Force =(0.5*density*frontal area*drag coefficient*velocity^2).
