Bicycle helmets stand the test of time

Helmets withstand the test of time. Using 770 donated bicycle helmets, Alyssa DeMarco, Dennis Chimich, and Gunter Siegmund found little or no evidence of helmet age-related deterioration in impact performance. Within the limitations of the sample and test conditions, these findings do not justify replacing a damage-free helmet every 2-10 years as recommended by some helmet manufacturers. A full-text, view-only version of the study “Age has a Minimal Effect on the Impact Performance of Field-Used Bicycle Helmets” is available here: http://bit.ly/helmetage.
