# Yaw Angle

Yaw Angle

Noun

Yaw Angle is the angle between the direction of the bike's longitudinal axis and the direction of the bike's velocity vector.

Example usage: The yaw angle of the bicycle was measured at 15 degrees.

Most used in: Professional cycling, particularly in the world of aerodynamics.

Most used by: Professional cyclists, aerodynamicists and bicycle engineers.

## What is Yaw Angle in Cycling?

Yaw Angle is a term used in cycling to describe the angle between a rider's direction of travel and the direction of the wind. This angle is important for cyclists as it affects the aerodynamic drag of the rider and their bike, as well as the amount of power required to maintain a given speed.

Yaw Angle is typically measured in degrees, with 0° representing a head-on wind and 180° representing a tailwind. For example, a rider cycling with a 20° yaw angle would be cycling at an angle of 20° with respect to the wind. The greater the yaw angle, the more aerodynamic drag the rider experiences and the more power they must exert to maintain their speed.

Studies have shown that aerodynamic drag increases exponentially with yaw angle, with a 10° yaw angle resulting in a drag increase of around 20% compared to riding with a 0° yaw angle. This means that even small changes in yaw angle can have a significant effect on a rider's performance, and it is important for cyclists to be aware of the wind direction and adjust their riding angle accordingly.

## The Origin of the Cycling Term 'Yaw Angle'

The term 'Yaw Angle' is used in cycling to describe the angle between the wheel and the direction of the bicycle's travel. The term was first used in the 1950s in the United States, when it was developed to measure the performance of bicycles and cyclists.

The term was coined by a team of engineers at the University of California, Davis. They used the term to describe the angle of the wheel relative to the direction of travel. It was designed to measure the performance of cyclists and bicycles in a range of different conditions, such as windy conditions, uphill and downhill terrain, and more.

Since its introduction, the term 'Yaw Angle' has become a standard tool used in cycling to measure performance and improve technique. It is used by cyclists and engineers around the world to measure the performance of bicycles and cyclists in a variety of different conditions.

The term 'Yaw Angle' is an important part of the cycling lexicon and has been used for over 70 years. It is a key tool used by cyclists and engineers to measure performance and improve technique.
