FAQs
Is this helmet suitable for casual trail riding?
While the Proframe Frequency is built for aggressive riding and downhill certification, its lightweight design and excellent ventilation make it suitable for serious trail riders who prioritize maximum protection.
How do I clean the helmet?
Clean the exterior and visor with mild soap and water using a soft cloth. Allow to air dry. Removable padding can be hand-washed gently.
What does the Mips® system do?
Mips® (Multi-directional Impact Protection System) is a low-friction layer inside the helmet designed to help reduce rotational forces transferred to the brain during angled impacts.
Can I mount other action cameras besides GoPro?
The included mount is designed for GoPro. While it might be possible to adapt other cameras using compatible mounts, it's not guaranteed and may affect helmet integrity if not done correctly.
What is the warranty on this helmet?
Please refer to the official Fox Racing warranty information for details on coverage periods and terms, as this can vary.
Does the helmet come with different sized pads?
Yes, the helmet includes an additional pad set to help users fine-tune the fit and enhance comfort.
What are the ASTM-F1952 standards?
ASTM-F1952 is a standard for downhill mountain bike racing helmets, indicating the helmet has met rigorous testing requirements for impact protection.
Troubleshooting
Helmet feels too tight or too loose
Adjust the fit using the included extra pad set. Swap different thickness pads for a more precise fit around the head and cheeks. Ensure the chin strap is correctly adjusted.
Visor is difficult to adjust
Ensure the adjustment mechanism is clean and free of debris. Gently operate the visor to its different positions. If stiff, apply a very small amount of silicone-based lubricant to the pivot points.
Chin strap buckle is uncomfortable
Re-adjust the length of the chin strap and ensure the buckle is positioned centrally under the chin. Some users find adjusting the side straps can improve comfort.
Fogging on goggles when wearing helmet
Ensure the helmet's ventilation is open. Adjust the visor position to allow for better airflow between the helmet and goggles. Consider using anti-fog spray on your goggles.

Compatibility:
Goggles: The helmet's visor is designed to be compatible with most standard MTB goggles.
Action Cameras: The removable under-visor mount is specifically designed for GoPro cameras, but may be adaptable for other small action cameras with appropriate mounting solutions.
Care:
Cleaning: Clean the helmet exterior and visor with mild soap and water. Use a soft cloth and allow the helmet to air dry completely. Avoid using harsh chemicals or solvents, as they can damage the helmet's materials.
Padding: The internal padding can typically be removed for gentle hand washing with mild soap and water. Ensure padding is completely dry before reinserting.
