Advanced Protection with MIPS® Spherical Technology

  • MIPS® Spherical System: Dual-foam layers act as a ball-and-socket, redirecting impact energy during crashes.

  • Extended Coverage: A full-cut design provides additional protection without compromising style.

Superior Comfort & Ventilation

  • Wind Tunnel™ Ventilation with 14 vents and internal channeling ensures maximum airflow.
  • Stack™ Ventilation at the brow line prevents fogging when paired with goggles.
  • Quick-Dry Padding and cheek pad ventilation keep you cool and dry during intense rides.

Optimised Fit & Compatibility

  • Roc Loc® Air DH Fit System allows for precise, on-the-go adjustments.
  • Goggle-Compatible Design with a tool-free, bolt-on visor for added versatility.
  • Spare Cheek Pads Included for customisable fit tuning.

Durable & Lightweight Construction

  • Hardshell with In-Mould Polycarbonate for impact resistance and durability.
  • Hardbody™ Lower Wrap enhances longevity and protection.

Designed for riders who embrace style over speed, the Giro Tyrant MIPS® Helmet combines next-level safety, exceptional breathability, and a modern look to redefine mountain biking protection.

Sizing Information

These size charts and conversions are meant to serve as a guide. Giro recommend you try-on before riding to ensure full comfort and performance.

Bike Helmet Size Guide

How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.

For helmets equipped with MIPS technology, please review the following warning: SOME MIPS® LOW-FRICTION LAYERS, ALONG WITH OTHER PARTS OF A HELMET, MIGHT CAUSE LACERATIONS TO THE WEARER’S HEAD/FACE IN SOME ACCIDENTS. THIS MIGHT OCCUR DUE TO THE HIGH PRESSURE ON THE SCALP FROM THE IMPACT OR AS A BY-PRODUCT OF THE LOW-FRICTION LAYER’S MOVEMENT IN CERTAIN ANGLED IMPACTS TO HELP REDUCE THE ROTATIONAL ENERGIES TO THE HEAD. IF YOU WOULD LIKE FURTHER INFORMATION, PLEASE CONTACT US.
