Selecting a Helmet
Important adjustment points on bike helmet straps.
Bicycle helmets typically bear a seal of approval from recognized organizations such as the Consumer Product Safety Commission (CPSC), American National Standards Institute (ANSI) or Snell Memorial Foundation. These approvals are based on the CPSC's 1999 ruling that all bicycle helmets must conform to basic specifications, including adequately protecting the head and "having chin straps strong enough to prevent the helmet from coming off in a crash, collision or fall." In addition, helmets intended for children aged 5 or younger cover more of the head to provide added protection.
A helmet should fit snugly on the head and not move more than an inch in any direction. Its straps should not impair vision. A light or bright color is preferable because it is more visible to motorists. A front visor helps shade the eyes. Vent holes help keep the head cool (see Reference 2).
Adjustment
Bicycle helmets are worn flat on the top of the head, covering the forehead and not tilting forward or backward. The chin strap fits snugly beneath the chin when clasped, but not to the point of being restrictive or uncomfortable. Typical helmet straps have at least three adjustment points controlling the length and positioning. Most helmets come with foam sizing pads that attach to the inside surface and can be used to ensure a snug fit. Helmets shouldn't tilt forward or back or from side to side (see Reference 1).
Replacement
Any time a bicycle helmet absorbs a significant blow, whether caused by an accident or other damaging contact, it should be replaced. A damaged helmet may not be able to withstand another blow.
When renting bicycling equipment, carefully inspect the helmet for dents, cracks and scrapes, which can indicate previous damage.If the helmet seems misshapen in any way, request another one (see Reference 1).
