Best MTB Helmet In 2024 – Top 10 New MTB Helmets Review
1. Fox Speedframe Pro
The Fox Speedframe Pro stands out as one of the top mountain bike helmets, earning a 5-star safety rating from Virginia Tech and securing the #2 spot among 258 helmets tested at their facility. Its thoughtful design and advanced safety features make it a favorite among riders.
At its core, the Speedframe Pro features a dual-density Varizorb™ EPS liner. This liner uses layers with different densities to better absorb impacts. The inner layer is 18% less dense than the outer one, acting as a crumple zone closest to the rider, while the outer shell remains strong and durable.
The helmet also includes MIPS® technology, which uses a low-friction liner to reduce rotational forces during impacts. Here’s a quick breakdown of its key specifications:
| Feature | Specification |
|---|---|
| Weight | S: 355±30 g, M: 380±30 g, L: 415±35 g |
| Ventilation | 19 "big bore" vents |
| Materials | 41% EPS, 20% nylon, 31% PC, 5% POM, 3% polyester |
| Price | $189.95 (MSRP) |
Other features include a 360° Fit System for a snug fit, a FIDLOCK SNAP buckle for easy fastening, and well-placed vents for excellent airflow. The XT2 liner is moisture-wicking, antimicrobial, and removable for easy cleaning. These details have earned the helmet an impressive 4.7/5 rating from 330 verified buyers.
"Varizorb technology allows us to vary the density and hardness of EPS throughout the shell to provide for low speed and high-speed impacts. 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."

Even professional riders back this helmet. Loris Vergier, Fox Global DH Athlete, shared his thoughts: "I’m really excited about this new helmet… Can’t wait to wear it. The shape and protection are enough for me, just what I asked for. It’ll be my daily use helmet, I love it!"
