While the style is understated, the Tyrant boasts countless under-the-hood tech breakthroughs including Wind Tunnel Ventilation and MIPS Spherical technology. MIPS Spherical utilizes a pair of foam layers that work like a ball and socket to redirect impact energy in a crash. One layer is EPS, which is well suited to high-speed crashes. The other is a lower density EPP foam with rebound characteristics to address low-speed, roll-around-in-the-dirt-type spills. The added coverage of this "full cut" design further enhances protective capability, while taking helmet design in a new direction for riders seeking style over speed. Style over speed. Designed to meet the needs of today's progressive trail riders, the Tyrant™ MIPS® helmet has attitude and innovations that usher in the modern era of progressive mountain biking.
