A key component in any time-trial tester or triathlete's kit is the helmet atop their head. It's the leading edge in the fight against aerodynamic drag.

Brands go to great lengths to test the aerodynamics of their helmets and calculate the relative advantages of each design, and the watts they may save. However, the truth is that it's difficult to make recommendations about time-trial helmets because their performance is so individual.

So, instead, this is a look at how they fit, feel, and hold up to routine use. What are the shortcomings and strengths that may affect comfort and speed? What are the design elements that stand out?

Depending on the length of time trials or triathlons, your decision-making priorities will change. I used all the helmets here in a size medium and each helmet saw many hours of use during my preparations for an upcoming 12-hour time trial.

Each of them ran true to size, but some were snugger than others.
