Absorbing 30% more energy than standard EPS foam, Koroyd is made up of thousands of co-polymer extruded tubes that provides extremely efficient and consistent energy absorption. The open cell construction allows cool air in, while expelling hot air from the rider's head.Īlso featuring MIPS, the Multi-Directional Impact Protection System. The honeycomb layer underneath the outer shell is Koroyd, Smith's proprietary safety tech that stacks up with the rest of the competition. Sometimes aerodynamics come at the price of proper ventilation but the 21 specifically designed air vents keep your head cool and feature specific channels to properly stow your sunglasses.
That testing paid off, as the Overtake was significantly more aerodynamic than most other race helmets in the same category.
Specifically engineered to help you win more podiums and provide a high level of confidence in safety.īorn out of the wind tunnel, the Overtake was meticulously tested against other race ready helmets in order to give you the most aerodynamic advantage. The Overtake is a super lightweight, aerodynamic helmet featuring some of the best, and revolutionary safety features in cycling today. This is because there are differences in test methods, impact conditions, risk calculations, and impact weightings specific to each sport.The Overtake MIPS road helmet is Smith's solution to create the ultimate race ready helmet. The score values in these ratings are not comparable to score values in our helmet ratings for other sports. The overall score estimates the number of concussions the average person would see if they experienced identical impacts at rates matching their weightings while cycling.Ī lower score indicates better helmet performance. Each risk is multiplied by its weighting factor and then summed together to compute an overall score. We compute concussion risk from measured peak linear acceleration and rotational velocity for each test. Velocities were selected to reflect common cyclist head impact velocities based on helmet damage replication studies.Įach lab impact is weighted based on how often a cyclist might experience a similar impact. We test 6 locations that are dispersed around the helmet at medium and and high impact energies. We measure linear acceleration and rotational velocity for each impact, which are correlated to concussion risk. A drop tower designed to match helmet-to-ground characteristics in cycling is used to test the helmets. We rate each bike helmet based on the results of 24 impact tests in our laboratory. Our ratings are an independent and objective assessment of helmet performance for consumers, free from manufacturer influence.
