Available in two price points, the new Fox Speedframe mountain bike helmet made quite a few social media waves when it was introduced back in February. We received our test helmet a bit before the embargo lifted and have enjoyed the last several months of testing from Central Oregon down to Baja Mexico. With a comfortable fit, killer graphics and color options and tons of technology, the Fox Speedframe Pro helmet has been a fun one to review.

The structure of the Fox Speedrame helmet comes from the dual-density Varizorb EPS foam. We reached out to Fox to get some information as to what exactly Varizorb is and they replied: “Varizorb technology allows us to vary the density and hardness of EPS throughout the shell to provide for low speed and high-speed impacts. For Speedframe Pro, the internal EPS is 18% less dense than the external EPS to create a crumple zone closest to the rider. Not only do we achieve weight savings and a more compliant internal structure, we also deliver a durable outer shell that allows Speedframe Pro to meet or exceed industry standard open face helmet testing requirements. Highlighting this fact is our recent Five Star rating from the renowned Virginia Tech Helmet Testing Lab.” Designed to help mitigate the damage caused by higher and lower speed impacts, the dual density foam blends materials to prevent brain trauma no matter if it’s a major impact or falling over while learning how to unclip from your new pedals.
