Lazer DualCore Technology Explained
The Next Evolution of Bike Helmet Protection
A bike helmet has one primary responsibility: help manage impact energy before it reaches the rider's head. That sounds straightforward but designing a helmet capable of doing that is anything but simple.
Not every crash looks the same. Some involve direct impacts with the ground or trail. Others occur at an angle, creating rotational forces that place very different demands on a helmet. Because real-world crashes vary so dramatically, modern helmet design requires more than a single approach to impact management.

That's exactly why Lazer developed DualCore. Building on decades of helmet engineering and the proven success of KinetiCore technology, DualCore is Lazer's most advanced protection platform to date. Rather than relying on a single layer of foam to perform every task, DualCore combines multiple integrated structures that work together to manage different types of impacts while also improving comfort, ventilation, and overall helmet design.
Why Different Impacts Require Different Solutions
When riders think about helmet protection, they often imagine a direct impact, like a simple fall straight onto the pavement or trail. While helmets certainly need to manage those kinds of impacts, real crashes are often much more complex.

A rider may strike the ground at an angle, slide across the surface, or tumble through rocks and roots. These impacts generate both linear forces, created by the initial collision, and rotational forces, produced as the head twists or rotates during the crash. Because these forces behave differently, they require different approaches to impact management. Rather than asking one material to do everything, DualCore assigns different jobs to different layers within the helmet.
The First Line of Defense: High-Density EPS
The outer portion of the DualCore system consists of a high-density EPS foam layer positioned directly beneath the helmet's outer shell. This layer is engineered to manage high-energy, direct impacts that often occur during hard falls onto pavement, rocks, or other trail obstacles. During a crash, the foam compresses in a controlled manner, helping absorb and dissipate impact energy before it reaches the rider.

This controlled deformation is one of the fundamental principles of modern helmet design, allowing the helmet, and not the rider, to absorb much of the energy generated during an impact.
The Second Layer: Integrated KinetiCore Technology
Direct impacts tell only part of the story. Many cycling crashes also involve rotational movement as the rider's head contacts the ground at an angle. To help address these forces, the second layer of DualCore incorporates Lazer's KinetiCore technology.
Inside the helmet, strategically engineered cone-shaped structures act as controlled crumple zones. During angled impacts, these structures compress and deform in carefully designed ways, helping dissipate rotational energy before it reaches the rider.
Unlike systems that rely on an additional internal liner, KinetiCore is built directly into the helmet structure itself. This integrated approach allows protection to become part of the helmet's architecture rather than an added component.

One Unified Protection System
What makes DualCore unique isn't simply the presence of two foam densities, however. It’s the way the entire system works together. A polycarbonate skeleton separates the two EPS layers, allowing each to perform its specific role while functioning as one integrated protective structure.
Rather than competing with one another, each component complements the others:
- The high-density outer EPS manages direct impacts.
- The integrated KinetiCore structures help address rotational forces.
- The dual-layer architecture creates a unified approach to impact management across a broader range of crash scenarios.
The result is a helmet engineered to better reflect the complexity of real-world riding.

Protection That Also Improves Performance
Because DualCore is integrated into the helmet from the very beginning of the design process, it also improves several aspects of overall helmet performance. Using DualCore, Lazer engineers were able reduce unnecessary material, improve internal airflow, lower the overall weight, and create a slimmer, lower-profile helmet.
Instead of adding protection after the helmet has been designed, DualCore allows protection, ventilation, aerodynamics, and comfort to evolve together as one complete system. For riders, that means a helmet that not only helps manage impacts, but also feels cooler, lighter, and more comfortable during every ride.

The Bottom Line
No two crashes are exactly alike. That's why no single material can effectively manage every type of impact. By combining two purpose-built EPS foam layers with integrated KinetiCore technology, Lazer DualCore creates a comprehensive impact management system designed to address both direct and rotational forces while simultaneously improving ventilation, weight, and rider comfort. The result is more than simply another helmet technology. It's the next generation of integrated protection that is engineered for the realities of modern cycling.
