Giro Tyrant Spherical Bicycle Helmets

About this item

• Mips Spherical : This technology utilizes a pair of foam layers that work like a ball and socket to redirect impact energy in a crash, eliminating contact with hard plastic against the skin.
• Progressive Layering™ : Two different materials manage impact energy: EPS Layer : Well suited to high-speed crashes .
• EPP Foam Layer : Lower density foam with rebound characteristics to address low-speed, roll-around-in-the-dirt-type spills .
• Enhanced Coverage : The "full cut" design further enhances protective capability.
• Fit System (ROC LOC® AIR DH) : This revolutionary system enhances cooling, fit comfort, and stability by slightly suspending the helmet off the skull, allowing cool airflow over the head.
• Cheek Pad Ventilation : Allows cool, fresh air to circulate inside the helmet for cooling and sweat management.
