Surprisingly, our quest for the perfect tube shapes didn't start in the Win Tunnel. It started with a new piece of technology, the FreeFoil Shape Library. Our engineers wrote an optimization algorithm and utilized a supercomputer (yes, we used an actual supercomputer) to help create new airfoil shapes with different weights, surface areas, and structural targets. Armed with this library of shapes, all with different aspect ratios, we could plug them into the different parts of the bike and test a variety of configurations to determine the fastest setup in the Win Tunnel.
