The Virginia Tech Helmet Lab has released ratings for 20 additional bicycle helmets, supplementing the initial set of 30 ratings published earlier this year.
The ratings give each helmet a score between one and five stars that reflects its ability to reduce the risk of head injuries. Six helmet models in the new batch earned all five stars, and nine models earned four stars.
The Bontrager Ballista MIPS, which scored highest in the first set of ratings, held onto its spot at the top of the pack.
“There’s a huge array of choices in the bike-helmet market; our goal with the ratings is to give cyclists an evidence-based way to make informed decisions about how to reduce their risk of head injury,” said Steve Rowson, an associate professor of biomedical engineering and mechanics in the College of Engineering and the helmet lab’s director. “We targeted some of the most popular models in our first set of ratings, and now we’re expanding outward so that we can reach as many consumers as possible.”
Cycling is associated with a higher number of sports-related head injuries than any other activity, primarily because it’s so popular: More than a third of Americans rode a bike in the past year.
Those cyclists have hundreds of helmets to choose from, and they’re all required to meet a safety standard set by the Consumer Product Safety Commission. But all a helmet has to do is perform well enough to pass an impact test calibrated for exceptionally severe injuries, like skull fractures, so there’s no way for consumers to tell the difference between a helmet that skated by and one that passed with flying colors.
Or there wasn’t, until the lab released the first set of bike helmet ratings over this past summer, the culmination of two years of research and testing in collaboration with the Insurance Institute for Highway Safety. The five-star scale clarifies the relative differences between helmets, allowing consumers to see which ones protect heads better than others.
