Road Helmet GIRO ARIES SPHERICAL MIPS — Size S (51–55 cm), Matte Carbon Red

GIRO ARIES SPHERICAL MIPS — Size S (51–55 cm), Matte Carbon Red is a road cycling helmet engineered for endurance and performance riding. The helmet combines SPHERICAL impact-attenuation technology with integrated MIPS to address linear and rotational impacts. Its aerodynamic shell and internal fit system deliver a secure, adjustable fit for riders with a head circumference of 51–55 cm, while ventilation channels and lightweight construction support all-day comfort during training and long-distance rides.

Advantages

The helmet’s dual-layer impact system reduces the forces transferred to the head by combining two independent layers that move relative to each other in an impact. Integrated MIPS adds rotational-impact protection. A low-profile shell and refined internal padding offer a balance of protection and comfort, and the adjustable retention system allows micro-adjustments to fit. Strategic venting maintains airflow without compromising structural integrity, and the helmet’s lightweight materials minimize rider fatigue on extended rides.

Suitable for

• Endurance road cycling and long-distance rides
• Daily training sessions and group rides
• Competitive road events where ventilation and fit are important
• Riders seeking a lightweight helmet with rotational-impact protection

Key specifications

• Size: S, fits head circumference 51–55 cm
• Finish: Matte Carbon Red
• Impact protection: SPHERICAL dual-layer impact-attenuation technology
• Rotational protection: Integrated MIPS system
• Construction: Lightweight shell with internal padding
• Ventilation: Multiple airflow channels for cooling
• Fit system: Adjustable retention for micro-fit tuning

How to use

Place the helmet on your head so it sits level and covers the forehead without tilting backward. Adjust the retention system until the helmet feels snug but comfortable; it should not move noticeably when you shake your head. Fasten and adjust the chin strap so it sits under the chin and forms a V-shape around each ear, with enough tension to keep the helmet stable. Inspect the vents and padding for proper placement and clean as needed according to the manufacturer’s care instructions.

Usage recommendations

Use this helmet for road and endurance cycling where both ventilation and rotational-impact protection are priorities. Replace the helmet after any significant impact or when visible damage or wear compromises its integrity. Follow local safety standards and ensure the helmet is the correct size for reliable protection.
