Assessment scenario: an adult road/gravel rider at 57 cm is comparing the Synthe Mips II style 130. The exact page names both uses and its chart includes 57 cm; this supports consideration and a try-on, not a CPSC claim or personal fit verdict.

Assessment scenario: Road or gravel riding at 57 cm
An assessment scenario only: an adult road/gravel rider at a measured 57 cm is comparing Synthe Mips II. The exact page names road and gravel and its adult 51–63 cm chart includes that number; it does not establish CPSC compliance or an individual fit.
Explore this buying guide ↗Why consider this model?
- Giro's exact US page names road and gravel riders and supports both operating plans.
- The adult S/M/L chart spans 51–63 cm; 57 cm falls within that published screening interval but does not establish individual fit.
- The page describes integrated Mips and Roc Loc 5 Air Mips, with independent fore/aft and vertical fit adjustments.
Tradeoffs to weigh
- The captured US page lists CE EN1078 but does not state US CPSC compliance; missing wording remains unknown and does not pass a hard CPSC filter.
- No exact-page weight or quantified vent count was established for the reviewed style, so this landing does not compare them by measurement.
- A 57 cm circumference match cannot determine head shape, comfort, secure fit or crash outcomes; no physical try-on was conducted.
- This page's Mips wording does not document Giro's Spherical/Mips system.
Check these before ordering
- Confirm the exact Synthe Mips II US style 100000000300000130, color and intended size; the observed Matte Black Underground route identifies no selected size.
- Inspect the exact product label and seek current CPSC documentation if that requirement is essential; CE EN1078 wording is not silently treated as the requested CPSC evidence.
- Try the exact size and shell, check stable retention and level positioning using Giro's instructions, and review seller return terms before purchase.
- Check current Giro recall notices and avoid used helmets with unknown crash history.
