Iíve been out-of-town and offline these past few days, so my apologies if someone posted this material in my absence, but here are the new safety ratings for helmets as determined by researchers at Virginia Tech. The researchers focused on the risk of concussions. Iíve not yet had time to study the methodology in depth; apparently it has some limitations. Hopefully it will be improved over time. Nonetheless I am glad Iíve procrastinated on buying a new helmet, as I plan to keep an eye on the ratings in my long-overdue purchase of a new helmet (mine is old and cheap and has endured some crashes. When I bought it at Performance yearsí back, I chose it Ďcause it was the only one small enough for my head).
