Engineering & Technical Analysis

The Ruroc Atlas 4.0 Street TC-2 utilizes a proprietary carbon fiber weave architecture that significantly reduces mass while maintaining superior torsional rigidity compared to traditional fiberglass composites. This structural integrity allows for the integration of the Street TC-2 communication system without compromising the helmet's crash performance, as verified by rigorous ECE 22.06 testing protocols. The internal EPS liner features a multi-density foam configuration designed to manage energy dispersion across different impact vectors, ensuring optimal protection for both frontal and rotational impacts.
