Advantages

The hard outer shell provides abrasion resistance while the inner liner is designed to absorb and dissipate impact energy. Lightweight materials reduce neck strain during longer rides, and ventilation channels help maintain airflow to improve comfort in warm conditions.

The helmet’s streamlined profile is compatible with a range of cycling clothing and accessories.

Key specifications

• Fit system: adjustable straps and rear retention dial for a secure fit
• Ventilation: multiple airflow channels for cooling
• Weight: lightweight design intended for adult use

How to use

Place the helmet level on the head so the front edge sits just above the eyebrows. Adjust the rear retention dial and side straps until the helmet is snug but comfortable, with minimal movement when you shake your head. Fasten the chin strap and trim excess webbing so the buckle sits under the chin and the straps form a V just below each ear. Inspect the helmet before each ride for obvious cracks, loose parts or worn straps and replace the helmet after any significant impact.

Usage recommendations

Use the helmet for everyday urban and road cycling; combine with visible clothing and lights for low-light conditions. Follow manufacturer care guidance: clean with mild soap, avoid solvents and prolonged sun exposure, and store in a dry place. Replace the helmet after a strong impact or when signs of material degradation appear.
