Fox Speedframe 5050 Mountain Bike Helmet: Protection and Comfort on the Trails
The Fox Speedframe 5050 mountain bike helmet is an open-face helmet designed for mountain biking on the trails. It combines the Mips® protection system, optimized ventilation, and a 360° fit system to provide a precise, comfortable fit on every ride.
With its iconic Fox style, adjustable visor, and features designed for mountain biking, the Speedframe 5050 is a complete option for trail rides and a range of riding styles.
Mips® Protection and a Precise Fit
The Mips® protection system is designed to reduce rotational motion transmitted to the brain during certain impacts. It absorbs and redirects energy and forces that could otherwise be transmitted to the brain.
For a precise fit, the Speedframe 5050 features a 360° fit system. Turn the dial to the left to loosen the helmet and to the right to tighten it. You can adjust the fit while wearing the helmet.
The rear retention system also has four adjustment points to adjust the fit height and best match the helmet to the rider's head shape.
Ventilation and Features Designed for Mountain Biking
Ventilation is optimized with channeled, molded EPS foam, designed to promote effective cooling during rides.
The helmet features a removable, washable moisture-wicking liner. Its one-handed adjustable visor is compatible with sunglasses and goggles, while a dedicated storage solution keeps your sunglasses close at hand when you're not wearing them.
