Aerodynamics is the study of how a solid body moves through the air . So when we relate that definition to the sport of cycling, it's about how a rider and machine overcome air resistance created by forward motion and the prevailing wind. HED designs and manufactures wheels and associated products that reduce this resistance. The lower the resistance, the faster you go.
At 25mph, 80% of an average rider's power output is used just to overcome the effects of wind drag when riding on the flat. Any reduction in this percentage results in either an increase in speed or a decrease in effort.
The speed you can achieve on your bike is determined by two factors. The first is how much power you are able to produce, measured in watts. The second is wind resistance, commonly referred to as "drag" and is usually measured in pounds at 30 mph in wind tunnel testing. The faster you go, the more wind drag there is to overcome. This is why a rider with a technical advantage is often able to go faster than one with a greater power output.
This is why you need HED. products. HED. designs products to be as aerodynmic as possible while still maintaining a functional advantage. Cadence recommends and stocks only aerobar units designed by HED. When it comes to being fully adjustable for that perfect fit, HED is the only choice.
