Product information

Description

GIRO Ratio Mips is an open-face helmet with a hard shell construction and integrated Mips rotational protection, designed for everyday cycling and micromobility use. The matt black finish and clean silhouette suit urban and commuter riders. The helmet combines an In Form fit system for quick, secure adjustability, Stack Vent airflow alignment to reduce goggle fogging, and Thermostat Control adjustable venting to tune ventilation on the move.

Advantages

The hard shell with a lower polycarbonate wrap provides durable impact resistance while keeping weight moderate. Integrated Mips aims to reduce certain rotational forces in oblique impacts without compromising fit. The In Form fit dial offers up to several centimetres of fine adjustment for a stable, customised fit, and vertical tuning helps achieve proper goggle interface. Thermostat Control lets you open or close vents quickly, and Stack Vent alignment helps maintain clear goggles and improved airflow.

Suitable for

  • Commuting and urban cycling
  • E-scooter and last-mile micromobility use
  • Riders who need a low-profile, matt black open-face helmet
  • Users who want a helmet with rotational protection and adjustable venting

When it may not be suitable

The GIRO Ratio Mips is an open-face helmet and does not provide the extended coverage of full-face helmets used in downhill mountain biking or aggressive BMX. It may not be the best choice for riders who require maximum chin and jaw protection or helmets certified specifically for motorized motorcycle use.

Key specifications

  • Helmet type: open-face bicycle helmet
  • Shell construction: two-piece hard shell with polycarbonate lower wrap
  • Protection system: integrated Mips rotational protection
  • Fit system: In Form adjustable fit dial with vertical tuning
  • Ventilation: Thermostat Control adjustable venting and Stack Vent alignment
  • Finish: matt black
  • Compatibility: designed for seamless fit with compatible goggles and aftermarket audio accessories

How to use

Place the helmet on your head so it sits level and covers the forehead. Use the In Form dial at the base to tighten until the helmet feels snug but comfortable; adjust vertical tuning to align with goggles if used. Use the Thermostat Control button to open or close vents as required; ensure straps are fastened and the chin strap is adjusted so only two fingers fit between strap and chin. Inspect the helmet before each ride for visible damage and replace it after any significant impact or when fit components are compromised.

What to consider before purchase

  • Measure head circumference and choose the correct size for a secure fit
  • Confirm the helmet type is suitable for your riding style (open-face vs full-face)
  • Check compatibility with any goggles or audio accessories you plan to use
  • Consider local safety standards and certifications required in your region

Usage recommendations

Use the In Form fit dial to achieve a stable fit, align the Stack Vent with goggle vents to minimise fogging, and adjust Thermostat Control according to temperature and exertion level. Replace the helmet after any crash that could affect its protective integrity.
