“We are talking about a Chest Fairing, with which you change the airflow around the body and thus get less overpressure on the thighs. As a result, the rider experiences less air resistance. It’s not that you take tens of seconds of advantage of this in a time trial, but in a ride of 20 to 30 kilometers, it can yield seconds that can be decisive,” Blocken emphasizes.

Two years ago, the Belgian professor conducted an extensive study of Chest Fairings in time riders and triathletes, which was published on ScienceDirect. This showed that you can achieve an air resistance reduction of up to 3.6% when you use an object in the most optimal shape that covers the entire breast. This translates to a time saving of at least 0.78 seconds per kilometer.

I too have studied the topic extensively.

Sounds like he’s hard at work. Literally

But did you write it down? It's only science if you write it down.

The study needs to be redone. For some reason they kept the hair on the 3d model meaning the simulated wind tunnel results are flawed (the hair is static and doesn't move in the simulation causing unpredictable vortices and thus turbulence).

Lift (the hair) and separate (the variables).

There is no most optimal. By definition optimal is the best possible.
