Safety Certifications
Ensure the helmet meets recognized safety standards, such as CPSC, EN 1078, or ASTM F1952, which indicate the helmet’s ability to provide adequate protection in off-road conditions.
Fit and Sizing
A helmet that fits properly is crucial. To protect your forehead, it should rest level on your head, with the front edge no more than an inch over your eyebrows. The helmet should fit comfortably without being too tight. The helmet should stay in place if you put it on your head, leave it unlatched, and bend over at the waist to evaluate the fit.

Not necessarily. All helmets sold must meet specific safety standards, ensuring a baseline level of protection. Higher-priced helmets often offer additional features such as improved ventilation, lighter weight, enhanced comfort, or advanced technologies like MIPS. However, a well-fitting helmet that meets safety standards can provide adequate protection, regardless of price.
4. How Do I Ensure a Proper Helmet Fit?
Measure Your Head
Use a flexible tape measure to determine the circumference of your head, positioning it about an inch above your eyebrows.
Try Before You Buy
Whenever possible, try on helmets to assess comfort and fit. The helmet should sit level on your head, with the front edge one to two finger-widths above your eyebrows.
Adjust Straps and Retention System
Ensure the chin strap is snug but comfortable, forming a “V” shape under your ears. The retention system at the back should be tightened to prevent movement but not cause discomfort.
5. Can I Use a Road Bike Helmet for Mountain Biking?
While you can use a road bike helmet for mountain biking, it’s not ideal. Mountain bike helmets are specifically designed to offer more coverage, especially at the back of the head, and often include visors to protect against sun and debris. They also typically have better ventilation suited for the varying speeds and efforts in mountain biking.
