How Kestrel Weather Meters Can Improve Aerodynamics in Bicycling
The aerodynamics of bicycling serves as an important element of its engineering. Especially in terms of competitive cycling such as the Tour de France, aerodynamics can greatly impact the speed and control of a bike.
Whether you're a pro cyclist or you have a passion for cycling and want to improve your game, here is how the Kestrel Weather Meter can help.
Aerodynamics: What is it and Why Does it Matter?
In the cycling industry, you'll find aerodynamic products ranging from bikes to helmets and wheels.
Air creates resistance when biking. In fact, it's impossible to avoid it because your bike and body will create air when it moves. The faster you go, the air moves faster as well.
Once you get into speeds of 30 mph, 90% of your energy is used to combat wind resistance.
Even though aerodynamics plays a part in how fast you go on your bike, it's a myth that it only matters in terms of speed. Even at slow speeds, you are still using a considerable amount of energy to fight against wind resistance.
If you want to test your aerodynamic cycling, this is one approach that a cyclist used.
Testing Aerodynamic Cycling: The Equipment
"My use case for the D3 is aerodynamic bicycle testing using the Chung Method. With this, you need a power meter, a speed sensor and a circuit you can use without traffic or another cyclist to avoid anything affecting the results. You also need to know the air density if you are wanting to get an accurate number (CdA) to then compare with other tests that you execute on different days (with different weather).
I attached a piece of Velcro to the back of the DROP and on the wall at the netball courts where I conduct aero testing.
Next, I export the spreadsheet from the DROP with all the data to calculate the Rho value (air density) based on dew point, temp and air pressure. Rho is then used when analyzing the data file which needs to contain power and speed."

The Chung Method involves finding a road with minimal traffic where you can ride up and down. The road also needs a dip. This article explains more about the benefits of using the Chung Method.
Kestrel Instruments are ideal to use when testing aerodynamics. They can provide incredibly accurate readings for both wind speed and wind direction, which allows you to plan and track performance. The wind can make the results of a race in either direction---it can even make you lose time in the worst-case scenario.
Knowing current wind direction, crosswind, and headwind can improve your cycling and prepare you for the ride ahead. Kestrel DROP data loggers are useful for aerodynamic testing. If you're interested in adding wind speed and direction measurements, the Kestrel 5500 Weather Meter is the right unit for the job.
Not only does wind speed and direction make a difference in cycling, but so does the weather. According to Accuweather, the best time for cycling is a sunny day since it provides the best visibility. During cold weather, the biggest obstacle is staying warm although icy roads are another serious consideration.
