Key Features
MIPS® Rotational Protection: Proven to reduce rotational motion by absorbing and redirecting energies and forces otherwise transmitted to the brain during a crash.
Dual-Density Varizorb™ EPS: Provides superior protection by spreading the force of impacts across a wider area of the helmet structure.
Fidlock® SNAP Buckle: A premium magnetic chin strap buckle that provides quick and secure entry and exit, even while wearing full-finger gloves.
Goggle Compatible Visor: A 3-position adjustable visor allows you to stow your goggles securely on the front of the helmet when they aren't in use.
360° Fit System: Allows you to dial in the perfect, customized fit every ride, ensuring the helmet stays stable on high-speed descents.
Ionic+® Antimicrobial Liner: Manages odor while wicking moisture away from your head to keep you cool and dry during high-output sessions.

✅ Why This IS For You
Safety-First Riders: If you want a helmet with a 5-star safety rating from Virginia Tech, providing maximum peace of mind for aggressive trail riding.
Goggle Users: Perfect for those who prefer the extra protection of goggles; the adjustable visor makes storage easy during transitions or climbs.
Premium Tech Fans: Ideal if you appreciate high-end touches like the Fidlock magnetic buckle and superior ventilation for long days in the saddle.
❌ Why This May NOT be for you
XC Weight Weenies: While light for a trail helmet, riders seeking the absolute lowest gram count for cross-country racing might prefer a more minimalist XC lid.
Full-Face Requirements: For bike park laps or sanctioned DH racing, you should consider a full-face option like the Fox Proframe for dedicated chin protection.
BFC Pro Tip
The Speedframe Pro is designed with a "Big Bore" vent at the front. To keep your goggles from fogging up during slow, humid climbs, tuck them under the visor—the airflow through the front vents will help pull moisture out of the goggle foam. Also, remember that the Ionic+ liner is removable and washable; keeping it clean will significantly extend the life of the helmet and keep it feeling fresh for every ride.
