Choosing the Right Helmet

1. Helmet Basics

Look for the latest safety technology explicitly designed for concussion protection.

WaveCel is a collapsible cellular material that is incredibly effective at preventing concussions caused by common biking accidents.

MIPS or Multi-directional Impact Protection System is a liner using slip-plane technology inside the helmet designed to move with your head upon impact. 

2. Helmets should match your riding style.

General/Recreation - Varies in coverage with some helmets providing more ventilation than others. Visors are a great option to block out the sun. 

Road/Performance- Aerodynamic and well ventilated to go the distance

Mountain- Provides more coverage, especially along the back where most MTB falls occur. Visors are also important to block out the sun. 

Youth/Kids - Don’t necessarily assume that a child’s helmet will fit until you measure their head. Many kids actually fit better in small adult helmets.

Did you know? Helmets should be replaced every 3-5 years

Helmet materials  will degrade over time losing their essential function in protecting your head.

3. Measure the Right Fit For Your Head


Use a tape measure (or a string then use a ruler to measure the length) to estimate the size.

Note:   If you are in-between sizes, go with smaller size

General Riding/Road Helmets

Correct Fit:  Straps are tight under the chin; Helmet sets level on the head. 

Wrong Fit:  Straps too loose; Helmet tilted back.

Mountain Bike Helmet

Correct Fit:  Straps are tight under the chin; Helmet sets level on the head. 

Wrong Fit:  Straps too loose; Helmet tilted back.

4. Check For Fit and Comfort

Put the helmet on your head.  Does this helmet come down far enough on your head? Is this helmet comfortable? 

The helmet may fit on the head but it may just not be comfortable. Even if it's slightly rubbing, this magnifies the longer you're riding.   If you feel slight hot spots, try on another helmet to compare.

If the helmet is too high on your head, go to the next size. 

1. Start in the Back

Most helmets have a wheel in the back so you can dial to tighten or loosen.   Make sure the helmet still remains in the correct fit position while dialing the wheel    

2. Adjust the Chin Straps

Buckle the chin strap to determine tightness or looseness.   You should be able to place one finger between your chin and the strap.    Now, adjust the side and chin straps to fit.   The side straps should be positioned under each ear.

3. Do the “Shake Test”

Once you’ve set your fit,  shake your head “no” to determine if the helmet is tight enough.   The helmet should not move on your head.   Keep adjusting the back or straps to correct your fit.
