Ponytails are slower than buns, according to wind-tunnel testing

BikeRadar recently published findings from wind-tunnel testing, concluding that a cyclist's ponytail creates more aerodynamic drag than a bun. While specific numerical differences weren't detailed in the headline, the implication is a measurable performance penalty for the former. This research, presumably conducted by an independent body or a cycling-specific aerodynamics lab, highlights the granular level of detail now being scrutinised in the pursuit of marginal gains.

This seemingly niche discovery underscores the relentless quest for aerodynamic efficiency in modern cycling, where even hair management can be a factor. From shaved legs to aero helmets and skin suits, every element of a rider's profile is now subject to scientific scrutiny. For professional riders, particularly those in time trials or breakaways, these fractional savings can accumulate, potentially influencing race outcomes and sponsor investments in research and development.

One might wonder if the UCI will soon regulate hairstyles. For now, it seems another marginal gain has been quantified, offering a new dilemma for those seeking every possible advantage.
