Road Helmet GIRO ARIES SPHERICAL MIPS, size M (55–59 cm), matte metallic coal/dusty rose, 2025

GIRO ARIES SPHERICAL MIPS is a road cycling helmet designed for riders who need a balance of safety, ventilation and adjustable fit. The size M suits head circumferences from 55 to 59 cm. The 2025 matte metallic coal/dusty rose finish complements an in-mold shell with integrated SPHERICAL impact technology and MIPS rotational protection to reduce forces transmitted during oblique impacts. Ventilation channels and internal air pathways promote airflow during long rides while the adjustable retention system ensures a secure and personalised fit.

Advantages

The helmet combines SPHERICAL impact technology and MIPS rotational protection to address linear and rotational forces in crashes. In-mold construction keeps weight low while maintaining structural integrity. Multiple ventilation channels and internal airflow design enhance cooling without compromising safety. The adjustable fit system offers micro-adjustment for a snug, stable position and improved comfort during endurance training. The matte metallic coal/dusty rose finish provides a subtle aesthetic suitable for a range of road cycling styles.

Suitable for

• Road training and group rides
• Endurance and long-distance cycling
• Amateur and competitive road racing
• Daily commuting on paved routes

Key specifications

• Size range: medium fit for 55–59 cm head circumference
• Protection: combined SPHERICAL impact technology and rotational protection system
• Construction: in-mold shell bonded to EPS liner for reduced weight
• Ventilation: multiple front-to-rear channels and internal air pathways
• Fit system: adjustable retention with micro-adjustment dial
• Finish: matte metallic coal with dusty rose accents (2025 colourway)

How to use

Place the helmet level on the head so the front edge sits approximately one to two finger-widths above the eyebrows. Adjust the retention dial until the shell feels snug but comfortable; the helmet should not move independently when you shake your head. Set the side straps to form a V just under each ear and fasten the chin strap so two fingers fit between the strap and your chin. Inspect the helmet before each ride for visible damage and replace it after any significant impact.

Usage recommendations

Use this helmet for regular road cycling, endurance rides and commuting on paved roads. For optimal protection, replace the helmet after a significant crash or if you notice cracks, deep dents or compromised structural integrity. Clean the helmet with mild soap and water, avoid high-pressure washing, and store it away from direct sunlight and extreme heat.
