I quit reading Bicycling Magazine years ago. But when they released this article about how to draft, I knew I couldn't take anything they print seriously. In particular is this line:
"To get the maximum benefit in a paceline, keep your wheel as close as possible to the one in front of you. Ideally, ride in a staggered position with your front wheel just overlapping the rear wheel of the rider ahead of you."
