A properly fitting road helmet should sit level on your head with the front edge about one inch above your eyebrows, or two finger-widths. The retention system should hold the helmet securely without creating pressure points. Shake your head vigorously—the helmet should move with your head, not independently. The chin strap should form a V below your earlobes and allow 1-2 fingers between the strap and chin. If the helmet rocks forward over your eyes or shifts side to side, adjust the retention system or try a different size or brand.
