Spherical Technology allows the helmet outer liner to rotate around the inner liner during a crash, and also. This is because there are differences in test methods, impact conditions, risk calculations, and impact weightings specific to each sport. The heart of the Giro Helios extraordinary design and performance is Spherical Technology, which utilizes a ball-and-socket design powered by MIPS the market-leading brain protection system that can help to reduce rotational forces. 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.
