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."
Fox Racing

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!"

A micro-adjustable dial offers 360-degree adjustments, while the removable, moisture-wicking, and washable padding ensures a snug fit for long rides. Extended rear coverage provides added protection to areas prone to injury during falls.

Research has shown that head trauma is a major cause of serious injuries in mountain biking, and the extended rear protection addresses this concern.

An adjustable visor with three positions adds versatility, allowing riders to manage their field of vision while shielding against sun, rain, and debris. The quick-adjust mechanism makes it easy to modify, even with gloves on.
