Giro describes Tyrant Spherical for progressive trail riders; the exact style-086 page documents a 51–63 cm S–L chart, a CPSC statement for people age five and older and Spherical Technology powered by Mips. These facts support checking the precise model and size, not a fit verdict or injury-outcome prediction.

Assessment scenario: Trail riding at 58 cm with CPSC and Spherical/Mips required
An assessment scenario for an adult trail rider at 58 cm who requires both a US CPSC statement and the named Spherical/Mips architecture. Tyrant Spherical is a documented chart-screen candidate, not a guarantee of fit or crash protection.
Explore this buying guide ↗Why consider this model?
- Giro’s exact US product page identifies progressive trail use and a full-cut design.
- The published S–L circumference interval is 51–63 cm, which includes 58 cm for chart screening.
- The same page states CPSC compliance for persons age five and older and documents Spherical Technology powered by Mips.
Tradeoffs to weigh
- A full-cut description does not make this a full-face helmet; the captured page does not describe a chinbar.
- The manufacturer’s 600 g figure applies to size Medium CPSC/CE configuration; it is not an independent measurement of every size or color.
- Spherical construction and certification statements do not predict an individual crash outcome; no hands-on or impact testing was performed.
- A published circumference interval cannot confirm head shape or personal fit.
Check these before ordering
- Verify the offer is the US Tyrant Spherical style 086, the intended size and the actual configuration; do not substitute another Spherical model.
- Check the physical unit’s CPSC markings, model identity, instructions and condition rather than relying only on a listing description.
- Confirm that the intended rider and fit align with the product instructions; review visor/goggle needs and the seller’s return terms.
- Check current Giro/CPSC notices before purchase and avoid a used unit with unknown crash history.
