Gravel sits at the crossroads of road and mountain biking. Depending on the terrain you ride, you can use the cycling helmet you have.
Road bike helmets are generally more aerodynamic and lighter. Stylistically, they look different.
Most mountain bike helmets have extended coverage on the back of the head, which is important if you fall backward. They usually have an integrated visor that shields the eyes from the sun and brush.
If you primarily mountain bike and are dabbling with gravel, you can save a few bucks and use your mountain bike helmet. Be sure to check out the Giro Manifest if you’re looking for a rock-solid dirt and gravel orient lid. If you’re coming to gravel from the road and want to tackle more remote roads and maybe dabble with single track, we’d err toward safety and recommend buying up into more protection.
Regardless, all bicycle helmets in the U.S. are CPSC-certified whether they’re designed for road or trail rides. You can safely wear a road or mountain-oriented helmet.
Helmets are sport-specific, designed to mitigate specific risks. Mountain bike helmets are not verified to protect a climber or mountaineer in an accident and vice versa.
