Giro Tyrant Spherical Helmet


Products can only be shipped to U.S. addresses.


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.

CHEEK PAD VENTILATION: Allows cool, fresh air to circulate inside the helmet to help cool you, and to address sweat management

HARDSHELL WITH IN-MOLD HARDBODY™ LOWER WRAP: The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight.

SPHERICAL TECHNOLOGY: Spherical Technology’s Ball-and-Socket design, powered by MIPS, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin.

PROGRESSIVE LAYERING™: Two different materials are used to manage impact energy: One layer is EPS which is well-suited to high-speed crashes. The other is a lower-density EPP foam with rebound characteristics that address the more common, low-speed impacts.

ROC LOC® AIR DH: Adjustable fit system enhances the helmet’s comfort, stability and interior ventilation while reducing the chances of accidental adjustment.

TOOL-FREE, BOLT-ON VISOR: Easily adjustable without need for tools or extra fiddling, and offers plenty of vertical adjustment to stage goggles when you’re not wearing them.
