>>1104484 is wrong. It's not about reducing the area of the bike as you very rarely get a 0 degree wind, but about the shape of the tubing that guides the wind around the bike. For example, due to lenticular shape of a non-drivetrain side of a disc wheel, it's not uncommon for said wheel to create zero drag at many front angles, or negative drag, i.e. the front wind literally propels you forward. It seems counter-intuitive, but those are the same mechanics that planes' wings use.t. has studied fluid mechanics
