Assessment scenario only: Bell 3Qtr-Air Mips is a current-reference Bell MTB half/three-quarter shell without a chin bar. Its exact US page lists CPSC, NTA 8776 and Mips Evolve; the printed M band includes this scenario’s 56 cm circumference. Bell’s L-row inch and centimeter lower endpoints disagree, and no chart establishes personal fit. Confirm the exact unit, label, condition and size in person.

Assessment scenario: Assessment scenario: charted 56 cm trail use with CPSC evidence
Assessment scenario only: a trail-use case at 56 cm where the comparison requires a model-level US CPSC statement. Bell lists 3Qtr-Air Mips with CPSC, Mips Evolve and an M chart band of 55–57 cm. The chart is a screening reference for exact-size try-on, not a fit guarantee, product-stock claim or inference about a visitor’s actual intent.
Explore this buying guide ↗Why consider this model?
- Bell places the exact style 100000000500000135 in its US MTB catalogue and describes a three-quarter/half-shell format without a chin bar. This assessment selects trail riding, but the category and broad use screen are not a claim about downhill equivalence or riding performance.
- The exact US page lists US CPSC, CE EN1078-2012, AS/NZ2063 and NTA 8776 and names Mips Evolve. Mips Evolve is a different label from Spherical Technology powered by Mips, and the CPSC panel states no age threshold.
- At the assessment’s 56 cm value, Bell’s printed M band (55–57 cm) includes the measurement. This is a manufacturer chart screen, not a fit conclusion; the shell still needs exact-size try-on and adjustment.
Tradeoffs to weigh
- The exact product page’s L row gives conflicting inch and centimeter lower endpoints; Bell’s printed metric row is retained without silently correcting the conflicting cell. Confirm the L conversion with the manufacturer before considering that size.
- The saved page does not state a numeric weight or vent count, head-shape profile, independently measured cooling, particular camera/light compatibility or an age-specific CPSC threshold. Feature copy does not establish package contents.
- This page cannot establish a seller offer, inventory, authenticity, individual-unit label, condition, impact history, fit or injury outcome. Current-reference means observed in the catalogue, not retail availability.
Check these before ordering
- Confirm Bell 3Qtr-Air Mips US style 100000000500000135, observed Rootbeer / M SKU BL-7203531, and the exact color/size option on the live manufacturer page; do not assume the observed M configuration is the only finish or stock state.
- Use Bell’s live chart and instructions; if considering L, ask Bell to resolve the displayed inch/centimeter mismatch. Try on the exact helmet and check stable, level fit and adjustment before relying on any circumference band.
- Inspect the exact helmet’s inside label, condition and prior impact history, and check current manufacturer and CPSC notices. Confirm seller return terms and precisely what accessories are included; verify any mount against the equipment rather than treating it as a package or compatibility promise.
