Wind Resistance and Aerodynamics when Cycling

The first thing that a cyclist needs to learn is to balance on the cycle and resist the wind. This is one more reason why there are different types of bikes for different uses. This is because of the aerodynamics that is required for the bike. Recreational bicycles will provide a posture that gives poor aerodynamics as it is not a feature required. The aerodynamics for a mountain bike will be at the best.

Aerodynamics in a bicycle is used to move against the wind which is known as "cutting". This is given by the posture of the body as well as the design of the bike like the seating and handlebars. The newer bikes and designs are coming out providing better aerodynamics and thereby better performance. The cyclist in an aerodynamic position will be able to cut through the air smoothly with reasonable speed.

Aerodynamics consists of two forces namely drag from air pressure and the surface friction. The drag is caused when an item is subjected to the air. It displaces the air from its surface. This separates the air causing a low pressure region behind the object and a high pressure in front of the object. This low pressure at the back will force the cyclist to be pulled back. The cyclist will therefore have to work against this drag in order to move forward.

The direct friction occurs due to the contact of air on the cyclist and bicycle. This has lesser impact. These two techniques are the key for your success in riding a bicycle.
