- Select size and colour for availability
The Details
This Giro Tyrant Spherical Dirt helmet is designed to provide maximal protection to trail riders but without sacrificing on style.
With MIPS Spherical and a hard shell in-mold construction with a polycarbonate hardbody lower wrap that provides maximal head coverage, the Giro Spherical Dirt helmet is design to keep you as safe as possible. Add to that progressive layering with different densities in the EPS outer liner and EPP inner liner, these help to absorb high and low speed impacts respectively.
In addition, the Tyrant is goggle compatible and has cheek pad ventilation. There's also a tool-free, bolt-on visor and slimline webbing. Lastly, the Tyrant is secured to your head via the Roc Loc Air DH fit system.
- MIPS Spherical
- Tool-free, bolt-on visor
- Goggle compatibility
Our Verdict
This Giro Tyrant Spherical dirt helmet packs style features in with safety, comfort and performance essentials.
Industry Reviews
The Giro Tyrant Spherical Dirt is a halfway house between a full-face and half-face mountain bike helmet. Whilst it's inevitably heavier than a standard open face lid, it offers a great deal of protection from the very low rear and its 'spherical MIPS' liner.
Comfy and well-vented considering the amount of coverage on offer; loads of coverage and great safety features
