Bicycle road racing is a team sport. To help the leader win, the assistants ride as windbreakers. Road races run at speeds of 40-50 km/h or more have more air resistance than you can imagine, and the second rider can ride with 65% of the power, while the third and subsequent riders can ride with less than 60%.
