Giro Tyrant Spherical Helmet

The Tyrant™ Mips® Helmet is designed to meet the needs of today’s progressive trail riders. Equally at home on forest
singletrack and at the dirt jumps, Tyrant’s attitude ushers in the modern era of mountain biking.

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.

Features

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 Fit System

This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort
and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc® Air
DH allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal
channeling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc 5, allowing you to easily
custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.

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.

Stack Vent Technology

Vents at the brow line help warm air to be drawn up and away from your goggles to eliminate fogging, while allowing
seamless integration with goggles.
