"In races where the speeds are exceeding 40, 50, 60 kilometers an hour, there's a massive aerodynamic advantage to having what we call an 'aero-helmet,'" Williams said.
They're commonly worn during road time trials, as well as on velodrome, an indoor arena for track cycling featuring steeply banked oval tracks. The surface and shape of the helmets are designed to be more conducive to speed, though different shapes may be faster on different people.
"All of these crazy shapes are just different companies' attempts to make the air flow around the frontal area of you and your bicycle in the best way," the 2020 Olympics bronze medalist said. "But they started to get very creative in the past couple of years."
