Designed by the same team that brought you the Moto-8 motocross helmet, the Bell Drop Mountain Bike Helmet lets you attack the course head on with a burly ABS plastic shell to protect your braincase. The Drop meets the safety requirements of not only the CPSC, but the ASTM, as well -- a standard which is voluntary and demands a higher impact velocity. This fullface Bell helmet’s visor side pivots increase durability in case you do decide to put that higher impact velocity to the test.
