Product Concept & Specifications
Ruroc (United Kingdom)Engineering & Technical Analysis
The Ruroc Atlas 4.0 utilizes a proprietary carbon fiber weave pattern that significantly reduces rotational inertia while maintaining structural rigidity against lateral impacts. Unlike standard polycarbonate shells, this composite layer absorbs high-frequency vibration energy, reducing rider fatigue during extended highway runs without compromising the impact dispersion matrix required by ECE 22.06 standards. The internal EPS liner features a multi-density zoned construction, providing superior protection for the occipital region while allowing for precise cheekbone contouring to accommodate diverse head geometries.
