Fox Racing Speedframe Pro Review

With roots in motocross, Fox Racing has been one of the biggest names in mountain biking apparel and protection for as long as we can remember. It's hard to go a single day out on the trails without seeing the Fox Head logo somewhere. Whether it's a jersey, gloves, kneepads, or a hydration pack, Fox's gear is popular for good reason. The Speedframe Pro is the most recent addition to their lineup of helmets, and it was designed to compete with the best helmets on the market. Fox pulled out all the stops for this model and ultimately delivered the complete package. Despite putting it through its paces for weeks, we couldn't find much to dislike.

Impact Test

All of the helmets in our review meet national safety standards, but our tests seek to identify any models that might stand out or fall behind. The Speedframe Pro lands right in the middle of the pack in terms of impact absorption.

Slow Impact Test Results

The Speedframe Pro showed average results. This chart displays the slow impact results from drop tests in the lab. It contrasts the Speedframe against the best-performing helmet in our review. An elevated curve suggests reduced safeguarding for the test head.

Fast Impact Test Results

In the fast impact tests, the Speedframe did noticeably better. The Speedframe performed near the top in the fast impact test. Only a few others bested it.

The Speedframe provides good head coverage and has a secure, comfortable harness system. The protective foam shell fits low on the head and drops down in the rear for extra occipital protection. The harness is adjustable both vertically and circumferentially to ensure that any head shape can find a secure fit.

Comfort

The Speedframe Pro is an out-and-out comfortable helmet. The interior contour of the protective foam shell doesn't create pressure points on the skull and should be versatile enough to fit most head shapes without issue. The inner shell was clearly molded with the rotational impact system in mind because the plastic liner doesn't feel like it takes up too much space on the helmet's interior. Early adopters of the rotational impact systems tended to feel a bit cramped with the plastic liner added to an otherwise well-sized foam shell, but we're glad to see that Fox is one of the companies now designing around the system.

Along with the comfortable shell, Fox also made sure to include a highly adjustable harness and an easily manageable strap system. The harness has a dial adjuster at the rear of the head with 26 clicks and a huge range of adjustment. The harness can also be adjusted vertically between four positions with a snap-fit system molded into the shell. The vertical adjustment allowed us to dial in the fit and ensure that the harness straps and dial didn't sit in an uncomfortable spot at the back of the head.

Ventilation

This is one of the most well-ventilated models we tested. Its nineteen total vents include three directly across the brow and two full-length interior channels for front-to-back airflow. Even at relatively low speeds, you can feel the vents start to work as air flows across the top of your head. As with any helmet, things begin to get a little bit sweaty on long climbs, but, importantly, the Speedframe Pro does a great job of quickly cooling things back down once you're at the top and your speed picks back up.

The interior padding also aids in keeping you cool out on the trail. It's relatively minimalist to reduce heat buildup, and it's made of an absorptive, sweat-wicking material to keep sweat from rolling down into your eyes or onto your eyewear.

Usability

As you would expect from a top-shelf helmet, the Speedframe Pro comes standard with just about every feature you could need out on the trail. On the helmet's interior, you'll find the already-discussed Mips rotational impact system, sweat-wicking padding, 360 Fit harness, and interior airflow channels. The padded liner is easily removable, washable, and constructed with antimicrobial material to minimize odor over the long haul.

The helmet's exterior features a large, adjustable visor with three indexed positions, one of which allows for goggle storage on the front of the helmet. The indexing is firm to ensure that the visor stays put when you set it in place, but this also means it's not as easily adjustable on the fly as some models we tested. Regardless, we were still able to use one hand to adjust the visor and stow our goggles on the helmet while riding. The helmet's outer shell also has subtle channels in the sides and rear to secure your goggle strap for the rowdy descents.

Rather than the standard chin buckle found on Fox's mid-range helmets, the Speedframe uses a Fidlock magnetic buckle. This is one of just a few models that we tested to use the Fidlock buckle, and we were skeptical of the system at first. After a few rides, though, we quickly got used to it and came to appreciate the ease of use while wearing gloves. All you have to do is get the two halves in the ballpark of where they need to be, and the magnet pulls them into place. Once it's locked in, it's as secure as any buckle system we've used.

Weight

When it came time to pull out the kitchen scale, the Speedframe Pro didn't particularly stand out from the pack. In fact, at 407 grams (14.4 ounces), this model falls right around the average among the trail helmets we tested. Given everything that this helmet has to offer, we don't think a mid-class weight is particularly a bad thing, but after the feature-packed Specialized Ambush tipped the scales at just 350 grams, our frame of reference was changed.

Out on the trail, the Speedframe Pro feels feather-like on your head despite its weight, but so do many of the models we tested. For reference, most of the other top performers in our test came in a bit lighter: The POC Tectal Race at 365 grams, the Smith Forefront 2 at 374 grams, and the 100% Altec at 381 grams. The differences are small in the grand scheme of things, but we would be remiss if we didn't point out that the Speedframe is a little bit chunkier than many of our favorite models.

Should You Buy the Fox Racing Speedframe Pro?

We spent weeks putting the Speedframe Pro through its paces and didn't find any issues with its performance. It's a comfortable, safe, feature-packed piece of gear that will last you for as long as you can avoid hitting the deck. Fox clearly put in the work to create a well-rounded product. Several other helmets will put a considerably larger dent in your wallet for a similar level of performance, so we think the Speedframe Pro is a great buy. It has just about everything you could ask for in a comfortable package, and it only gives up a few grams to its more-expensive counterparts. Unless you're a gram counter hunting for the lightest kit available, the Speedframe is one of the best helmet options out there.

What Other Mountain Bike Helmets Should You Consider?

If you like the Speedframe Pro's robust construction but are looking to save some money, take a look at the lazer coyote kineticore, which offers top impact test scores. If you're looking for a lighter option, consider the Smith Engage Mips.
