A cycling helmet is the most important piece of equipment that every cyclist should own. The majority of cycling fatalities occur due to head injuries. A helmet helps to protect ones head if the cyclist should happen to crash. There are many different styles of helmets to choose from including mountain bike helmets, road bike helmets and BMX helmets.
Determine your budget. Helmets can cost anywhere between $25 and $200.
Purchase a certified helmet. Look for a CPSC (Consumer Product Safety Commission) or ASTM (American National Standards Institute) or Snell Memorial Foundation sticker inside the helmet.
Properly fit the helmet. The helmet should sit level on ones head and should not be tipped forward or backward. The helmet should fit snuggly, but not be uncomfortably tight. If the helmet slides all over the place, choose a smaller helmet.
A good quality helmet will have an adjustable chin strap and pads which can be attached to the inside of the helmet to fine tune the fit. Better quality helmets have an adjustable ring at the back of the helmet, which can be made tighter or looser as needed.
