What makes a bike aerodynamic?
Aerodynamic drag consists of two forces: air pressure drag and direct friction (also known as surface friction or skin friction). … Direct friction occurs when wind comes into contact with the outer surface of the rider and the bicycle. Racing cyclists often wear “skinsuits” in order to reduce direct friction.

At what speed does aerodynamics matter on a bike?
At speeds over 9 mph, it’s the dominant force of resistance. By the time you hit about 30 mph, 90 percent of your power goes into overcoming air resistance, or what scientists call aerodynamic drag.
How do you reduce drag on a bike?
8 Ways To Cut Drag On The Bike
- Go tight, not baggy. Your choice of clothing affects your aerodynamics, thanks to something called friction drag. …
- Wear the right lid. …
- Lower isn’t always better. …
- Shorten your cranks. …
- Upgrade to deeper rims. …
- Invest in an aero bike. …
- Take yaw angles into account.
Why do cyclists wear tight clothes?
The explanation for this odd behavior is aerodynamics. The main thing that slows cyclists down is drag. Drag is a backward force created by air friction. Cyclists (especially while racing) do all they can to minimize this drag.
