The Tyrant™ MIPS® is designed to meet the needs of the new generation of progressive bikers. Whether on the home trail or on dirt jumps, the Tyrant heralds a new era of mountain biking. Beneath the understated exterior style, the Tyrant shines with a myriad of technical innovations including Wind Tunnel™ ventilation, Stack Ventilation and MIPS Spherical technology. MIPS Spherical combines two helmet inner shells that function like a ball-and-socket joint to redirect rotational energy during a fall. The outer helmet shell, made of EPS, is great for high-speed falls. The inner shell made of EPP has lower density and rebound properties to absorb impact at low speed. The additional coverage of the "Full Cut" helmet expands the protection zone and gives a whole new direction to the helmet design.
