Fox Racing Speedframe Mountain Bike Helmet White Solid, Small — Mips protection & 360° Fit System

Fox Racing Speedframe is a lightweight, trail-ready mountain bike helmet with Mips protection, optimized venting, and a 360° Fit System for a secure, comfortable ride.

The Fox Racing Unisex Speedframe Helmet in White Solid combines the aggressive, performance-driven look Fox is known for with engineered safety and fit features designed for trail use. Built with in-molded EPS foam, channeled vents, a removable moisture-wicking liner and Mips® rotational impact technology, this small-sized helmet balances protection, cooling and rider comfort. A one-hand-adjustable visor and sunglass-specific storage make it a practical choice for every ride.

How does the Speedframe help protect me on rocky trails?

The helmet includes the Mips added protection system to reduce rotational forces during angled impacts, paired with an in-mold EPS shell that manages linear impact energy. Together they provide a multi-layered approach to help mitigate different impact dynamics encountered off-road.

• Mips layer absorbs and redirects rotational forces
• In-molded EPS foam for impact energy management
• Durable outer shell resists abrasion and puncture

Will this helmet keep me cool on long climbs?

The Speedframe’s optimized venting channels air through the in-molded EPS to promote continuous airflow and heat dispersion. Strategic vent placement and internal channels keep air moving across the head for improved comfort during extended efforts.

• Front-to-back channeling for consistent airflow
• Large intake and exhaust vents to accelerate heat removal
• Moisture-wicking liner reduces sweat buildup

How do I get a perfect fit with the 360° Fit System?

The 360° Fit System allows micro-adjustments around the head to lock the helmet in place without pressure points. Combined with easily adjustable straps and a one-hand dial, it’s simple to dial in a secure, stable fit before and during rides.

• Rear dial for quick circumference adjustment
• Contoured shape minimizes movement during impacts
• Removable liner and strap adjusters personalize comfort

What convenience and storage features does the Speedframe offer?

Practical touches include sunglass-specific storage, a removable washable liner, and a visor compatible with both goggles and sunglasses. These features make it easy to adapt the helmet to trail, enduro, or everyday mountain biking situations.

• Sunglass storage area keeps eyewear secure while climbing
• Removable, washable moisture-wicking liner for hygiene
• One-hand-adjustable visor accommodates goggles and shades
