Giro Tyrant Spherical

Unlike traditional MIPS liners that use a plastic slip-plane, Spherical technology uses two distinct layers of foam that act like a ball-and-socket joint. This allows the outer liner to rotate around the inner liner during an impact, which is more effective at managing rotational energy while maintaining a secure fit.

Yes, despite its full-coverage design, the Tyrant features 14 vents with internal channeling and brow-line ventilation. While it offers more coverage than a standard XC helmet, the airflow is engineered to keep you comfortable during intense trail sessions.

The full-cut design extends coverage further down the back of the head and over the temples compared to traditional open-face helmets. This provides extra peace of mind and protection when riding technical, aggressive terrain.

Yes, the Roc Loc Air fit system lets you easily dial in the fit tension and vertical position with one hand. It also suspends the helmet slightly off the top of your head, which helps improve airflow and cooling.

The Tyrant uses progressive layering: an EPS outer liner designed to manage high-speed impacts, and an EPP inner liner optimized for lower-speed crashes. This dual-density approach ensures the helmet is prepared for a wider range of impact scenarios.
