Product Concept & Specifications
Leatt (New Zealand)工学設計 & 技術分析
The Leatt MTB 4.0 V21 utilizes a dual-density EPS liner system engineered to absorb high-impact energy while maintaining a low center of gravity for optimal bike handling. Its aerodynamic shell profile reduces wind turbulence, resulting in a drag coefficient of 0.34 and effective acoustic dampening that lowers noise levels by approximately 4dB compared to standard full-face designs.
