How to Choose a Bicycle Helmet
A bike helmet can literally save your life if you fall and bump your head during the ride, but it will do you much less benefit (maybe not help at all) if it doesn’t fit you.
Here’s how to find and find the right size.
Measure your head to find the right size for your helmet
The size of the helmet depends on the circumference of the head. If you’re not sure how big your head is,grab a tape measure and find out .
Measure (in centimeters) where the helmet will sit on your head, that is, at the widest point above your eyebrows and ears. Compare your measurements to the helmet sizing chart – but keep in mind that sizes are sometimes referred to as kids, youth or adults, and sometimes small, medium or large.
As helmets vary in size, shape, and design from one manufacturer to another, try them on before purchasing. This is especially important if your helmet doesn’t offer many adjustment options (for example, some have a fixed strap length).
And if you buy a helmet for a child, do not buy him the one he “grows up” into. Helmets should always fit right now , even if that means you have to resize later.
Adjust the helmet on your head
Your helmet should sit flat on your head and not bend at an angle forward or backward or side to side. If you can fit about two fingers wide between the eyebrows and the helmet, then it is in the right place.
Some helmets have a fixed size, meaning they only fit a certain head circumference. Others are adjustable within a specific range for a more accurate fit. If you have an adjustable one, turn the rear disc until the helmet sits securely and comfortably on your head.
Add or adjust the included foam pads to further customize the fit.
Adjust the side straps
The intersection point of the V-shape of the helmet straps should be directly in front of and below the ears. Move the slider up or down the straps to tighten or loosen V.
Adjust the chin strap
The buckle on the chin strap should be centered and when closed, you should only be able to stretch one or two fingers between the strap and your chin. Tighten or loosen as necessary.
Check compliance
The Cycling Helmet Safety Institute offers two fit tests :
- Lift the front of the helmet with your palm up and back. If it moves more than an inch, adjust the fit.
- Shake your head in all directions. If the helmet shifts, adjust the straps.
Finally, make sure the helmet is comfortable to wear. If that’s not the case, you’ll constantly need a fit – or just give it up altogether. And if you do crash and hit the helmet, replace it, even if you don’t see any obvious damage.
