aerodynamics

Tri didn’t copy aero - it taught it. Here we look at the historic images, oddities, and athletes who hid heads, moved bottles, and nudged rules to reshape the way we look on the bike leg.

A growing number of elite athletes and bike designers swear by the aerodynamic benefits of stacking multiple bottles between their arms. We dove deep – and conducted our own DIY testing – in search of answers.

Your expensive aero helmet could actually be slowing you down. An aerodynamicist explains why aero helmets have evolved (yet again) and how to use them right.

The authority on aerodynamics to pros like Lionel Sanders breaks down basic aero terms, aerodynamic science, why it all matters, and what you should be focusing on to (actually) get faster.

We break down the data from real-time aerodynamic drag testing to finally put an end to the confusion of the most aero way to carry water on the bike.

Aerodynamics are everything. Improve yours.
