Product Concept & Specifications
GMax (United States)Engineering & Biomechanical Safety Analysis
The GMax MD-01S Tech TC-5 features a polycarbonate shell for lightweight durability and impact resistance. Its modular design offers versatility, while the intermediate oval head shape ensures a comfortable fit for most riders. The helmet includes advanced ventilation with adjustable airflow channels to keep the rider cool, and its safety tech meets rigorous standards for protection. The interior padding is designed for comfort, with moisture-wicking materials to reduce fatigue on long rides.
The GMax MD-01S Tech TC-5 is engineered as a high-integrity Modular protective system, utilizing a structural shell constructed from Polycarbonate. This structural layup is engineered to provide progressive kinetic energy dissipation during impact deceleration, distributing localized shock across outer lamina layers while minimizing deformation transfer into the internal multi-density EPS liner.
Certified to DOT, ECE 22.06 protocols, the architecture is subjected to rigorous linear deceleration limits and oblique impact evaluations to mitigate rotational acceleration forces associated with diffuse axonal injury. For a deeper breakdown of rotational thresholds and impact testing speeds, consult our ECE 22.06 vs DOT vs SNELL engineering benchmark.
Internal geometry follows a Intermediate Oval cranial profile, designed to mitigate focal pressure hot spots across the parietal ridges while maintaining uniform radial clamping pressure along the zygomatic arch. Riders seeking optimal retention stability and break-in guidance should review the cranial aspect ratios and head shape guide as well as our 3D cheek pad density protocol.
Shell composite integrity and acoustic sealing are further optimized through channelized EPS porting and aerodynamic laminar profiling. To learn how shell composites resist stress cracking under prolonged environmental cycling, inspect the composite material comparative matrix.
