Road Helmet GIRO ARIES SPHERICAL MIPS size S (51–55 cm) matte metallic coal dusty rose

GIRO ARIES SPHERICAL MIPS size S (51–55 cm) is a road cycling helmet engineered for on-road training and racing. It combines a lightweight shell with SPHERICAL impact management and MIPS rotational protection to reduce forces transferred to the head. The matte metallic coal finish with dusty rose accents delivers a subdued, technical aesthetic while the internal fit adjustments and ventilation channels provide stable positioning and airflow appropriate for sustained efforts and varied riding conditions.

Advantages

The helmet integrates SPHERICAL technology for predictable linear impact performance and MIPS for rotational impact mitigation, together providing multidirectional protection. Precision fit features allow helmet-level adjustment across the 51–55 cm size range to ensure secure contact and minimize movement during aggressive riding. Designed for road aerodynamics and cooling, the helmet balances low weight with ventilation pathways to help manage heat without excessive drag.

Suitable for

• Road training and endurance rides
• Competitive road racing and time trials
• Group rides and club events
• Commuting on paved roads

Key specifications

• Size: S, fits head circumference 51–55 cm
• Protection systems: SPHERICAL impact management and MIPS rotational protection
• Shell finish: matte metallic coal with dusty rose accents
• Fit adjustment: internal dial or retention system for micro-adjustments
• Ventilation: multiple air channels for airflow and cooling
• Weight: low-weight construction optimized for road use
• Intended use: on-road cycling—training, racing, and commuting

How to use

Choose the S size to match a head circumference of 51–55 cm, then adjust the internal retention system so the helmet sits level on the head with the front edge approximately two finger-widths above the eyebrows. Fasten and tighten the chin strap to a comfortable, secure fit that prevents front-to-back or side-to-side movement. Use the ventilation channels and adjust positioning to maintain airflow during rides. Inspect the helmet before each use for visible damage and replace it after any significant impact.

Usage recommendations

For optimal protection and comfort, pair correct sizing with regular adjustment of the retention system. Replace the helmet if it sustains a hard impact or shows signs of structural damage. Clean the helmet shell and padding with mild soap and water; avoid solvents and high-temperature drying. Store the helmet in a dry, cool place away from prolonged sunlight to preserve the matte metallic finish and internal materials.
