Explore this buying guide ↗Why consider this model?
- Giro’s exact adult style-017 page explicitly describes fire-road adventures and singletrack.
- The UA size maps to 54–61 cm in Giro’s general bicycle chart; this identifies a range to try, not personal fit.
- The page names integrated Mips, Roc Loc Sport and 330 g for manufacturer-listed size UA.
Tradeoffs to weigh
- The captured exact US page lists CE EN 1078 but no CPSC statement, so the model fails a CPSC-required filter.
- No Spherical designation, exact vent count, head-shape profile or independent fit result is recorded.
- The 330 g value is manufacturer-listed for UA and is not independently measured.
Check these before ordering
- Confirm adult Fixture Mips II US style 100000002400000017 and exact size/color; do not substitute youth style 351 or XL.
- Inspect the exact helmet’s standard marking and instructions.
- Try on, verify package/visor details and return terms, and check current recall notices.
