Road Bike Helmet Men Women 21 Ventilation Holes Wind Tunnel Design EPS Shell 240g Adjustable

This bike helmet uses wind tunnel principles to shape its 21 ventilation holes, optimising airflow and reducing wind resistance for both road and mountain cyclists. The aerodynamic design is a practical fusion of mechanics and aesthetics, giving riders a sensory experience of controlled air movement. Built with a high-grade PC colour plastic shell bonded to high-density EPS foam, the helmet passes CE safety certification. Its construction balances a strong outer shell that disperses external force with a soft inner density that absorbs impact energy. Weighing only 240g, it suits riders who value light weight and adjustability.

Features and Construction

The helmet combines professional safety features with everyday comfort. The adjustable head circumference regulator, chin strap, and super wear-resistant pull buckle make fitting quick and secure. The Velcro lining can be removed and washed easily.

Material and Build

The outer shell uses high-grade PC colour plastic, while the inner layer is high-density EPS foam. These materials are bonded together during moulding to create a single, impact-resistant structure. The helmet meets CE safety certification – the outer shell disperses external force, and the inner density absorbs impact energy, providing layered protection.

Size and Practical Fit

The helmet fits head circumferences from 58cm to 63cm, with a head width of 18cm and length of 22cm. The professional head circumference regulator lets you dial in a snug fit, and the chin strap with a super wear-resistant pull buckle keeps the helmet stable during rides. The total net weight is only 240g, reducing neck strain on long journeys.

Uses and Placement

The wind tunnel duct design and 21 ventilation holes make this helmet suitable for a range of cycling activities, from daily commuting to weekend sportives.

Event or Professional Use

For road racing or time trials, the reduced wind resistance from the aerodynamic vents helps maintain speed. The lightweight construction also benefits riders who need to keep effort low over long distances. The CE certification provides assurance for competitive use.

Everyday Home Use

For urban cycling or mountain bike trails, the helmet’s adjustable fit and removable lining make it practical for daily use. The ventilation keeps the head cool in warmer weather, while the durable shell protects against minor impacts. It is compatible with most bike types including road, mountain, and city bikes.

Benefits and Buying Value

This helmet offers reliable impact protection with a lightweight, adjustable design. Its construction materials and wind tunnel-inspired ventilation are backed by CE safety certification.

Reuse and Low Maintenance

The Velcro lining can be removed and hand-washed, keeping the helmet fresh over time. The super wear-resistant pull buckle and PC shell are built for regular use without rapid degradation. Replacing the lining when needed extends the helmet’s lifespan.
