2025 Fox Speedframe Pro Defy Helmet

Performance trail helmet with open visor

Designed with input from our professional mountain bike athletes, the Speedframe Pro Backfade helmet earned the highest rating (5 stars) in Virginia Tech's bicycle helmet safety test for good reason. This high-performance open-face mountain bike helmet has unique features to keep you protected on every ride. At the top of the list is the Mips® Air Node protection system, a low-friction layer for lightweight, fully vented helmets designed to reduce rotational motion and divert forces away from your brain in the event of a crash. Dual-density Varizorb™ EPS provides increased impact protection by dispersing impact forces over a larger area. The BOA® Fit System lets you fine-tune the helmet for the perfect fit every time you ride. The removable and washable Ionic+® liner is antimicrobial and manages odors while wicking moisture away from your head. The visor is adjustable with one hand and can be used with both sunglasses and goggles. The helmet also has a dedicated storage solution for sunglasses. Looking for a performance trail helmet?
