The Tyrant MIPS was developed to meet the needs of the new generation of progressive bikers. Whether on the home trail or on dirt jumps, the Tyrant ushers in an era of mountain biking. Underneath the understated exterior style, the Tyrant shines with myriad technical innovations like Wind Tunnel Ventilation, Stack Ventilation and MIPS Spherical technology. MIPS Spherical combines two helmet inner shells that work like a ball-and-socket joint to redirect rotational energy during a fall. The outer EPS helmet shell 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.
