The problem: Aerodynamic testing is mandatory— but usually not optimized
Aerodynamic testing has become mandatory in modern triathlon. But the way it’s usually done is scientifically weak.
Most testing still uses the “one factor at a time” approach
It feels controlled. It feels methodical. But statistically, it’s flawed.
What’s wrong with current practice:
No interactions: Wheels, tyres, yaw angles, and positions influence each other—but are tested in isolation.
No generalization: You only know something about the exact combinations you tested—nothing about all the others.
Missed gains: The fastest setup might be a combination you never tried.
You’re spending time and money on testing, but still optimizing in the dark.
