rlukeOne of the best helmets I have owned. The fit is adjustable on the fly with a simple roller on the top of the helmet. The Rollsys fit system adjusts around your entire head and works really well. I have this helmet as well as the Lazer O2XC which is the MTB version. The O2XC is slighly preferable because the rear head basket is adjustable up and down and allows for an even better fit to different head shapes and sizes.
