Fox Racing recently dropped the Speedframe trail helmet for trail riding. We caught up with the guys from Fox at the Winter Bike Connection event in Italy. They gave us a Speedframe Pro to test, the top-end feature-packed model, priced at $159.95. Fox also offer a $109.95 Speedframe with fewer features, but importantly, both have the MIPS-C2 rotational impact protection system. Here are our thoughts on the Fox Speedframe Pro.

Tried & Tested: Fox Speedframe Pro

The Speedframe Pro helmet has earned Virginia Tech’s best rating (5 STARS) in its Bicycle Helmet Ratings program. Not too shabby for a rather svelte helmet that actually looks good too. The Fox website reports a weight of 360g but doesn’t indicate what size that corresponds to. We weighed a size small in at 340g.

My head measures up at 52cm, so I wore the small Fox Speedframe Pro, recommended for circumferences of 51cm-56cm. The 360° fit is just that. The helmet fits securely and comfortably all the way around my head, with no loose points or pressure points anywhere. The rear dial offers 28 clicks of adjustment.

The chin strap length is adjustable but the divider position is not. That said, I felt no need to adjust the position of the divider. It sits at an appropriate position underneath my ear lobes. Its lack of adjustability means that, from the divider up, the strap length can’t actually change. Less fiddling. More riding.

The Speedframe Pro has the premium-feature Fidlock SNAP buckle, which uses a magnet to slide into position. It’s super easy to use, even with gloves on, and the magnet lets you to fasten it with one hand.

The visor of the Fox Speedframe Pro can sit in three different positions. Push it to the top position to stow goggles underneath. We used the helmet with two different types of MTB goggles; Smith Squad and Leatt Velocity 4.5. Both are compatible with the Speedframe. The helmet’s rear is shaped with a ridge to stop the strap slipping up or down.

The Speedrame features cavernous ventilation, by virtue of the 21 vents with internal channeling for maximal airflow. The shell of the helmet wraps the whole way around and underneath the edges to protect the dual density Varizorb EPS. The XT2 comfort liner is removable and washable, and features anti-microbial properties to manage odor.

The Bottom Line: Fox Speedframe Pro

We’d highly recommend the Fox Speedframe Pro. It is a superb helmet for trail riding, packed with plentiful safety features. The design is well thought through, from the visor to the buckle, from the ventilation to compatibility with goggles. It is comfortable enough for a long day in the saddle. It is pretty lightweight and the coverage isn’t entirely comprehensive; it is just a trail helmet after all. We wouldn’t be going full send in it. We’d rather put our trust in the Dropframe for that.

The cheaper one

Fox also offer the Speedframe MIPS, the lower-end version priced at $109.95. As the name suggests, it retains the MIPS-C2 rotational impact system but it does lose the dual density Varizorb EPS offered by the Pro. It also loses the Fidlock buckle, replaced by a standard plastic buckle, and drops the gloss finish for matte.

  1. Why are the top end helmets always the ones tested? I’m looking at getting the non-pro version for my wife and whilst I can work out if I want to pay more for the fidlok buckle, I have no idea if the dual density eps is worth it. Does it make it safer? If so, by how much?

    • Hi Rob. Thank you for your question. Fox gave us only the top end Speedframe to test. I put your question to them. Here is their response:

      ““The combination of softer and harder EPS (Dual Density) provides better management of a variety of impacts: Softer EPS offers a good protection against low impacts while the harder one is designed to absorb higher impacts.

      Dual Density improved protection by spreading the forces of impact across a wider surface area compared to standard EPS.

      We’re confident with how Dual Density performs relative to standard EPS, but are not in position to share testing reports as they are proprietary in nature and part of our secret sauce.”

      I asked Fox about the outcome of the Virginia Tech Test on the Speedframe MIPS. They said they only sent to Speedframe Pro for testing.
