Product Concept & Specifications
Ruroc (United Kingdom)Engineering & Technical Analysis
The Ruroc Atlas 4.0 utilizes a proprietary carbon fiber weave architecture that significantly reduces rotational energy transfer during impact while maintaining structural rigidity. The internal EPS liner is segmented into three distinct zones to optimize energy absorption across different crash vectors, ensuring maximum protection without compromising comfort. Aerodynamic shaping has been refined through computational fluid dynamics (CFD) simulation to minimize drag and reduce wind buffeting at high speeds.
