Product Information

Full details

The HJC Adwatt is a professional-grade time trial helmet designed for competitive cyclists seeking maximum aerodynamic efficiency and thermal management. Developed through extensive wind tunnel testing, this helmet offers a significant drag reduction advantage, making it the choice for elite athletes like Victor Campenaerts to break the UCI Hour Record. While it delivers industry-leading speed and cooling, users should note that the specialized aerodynamic shape is optimized for aggressive, head-down time trial positions rather than casual upright riding.

FAQs

Does the HJC Adwatt work well without the visor?

Yes, the helmet is specifically engineered to be efficient and aerodynamic whether you choose to use the mirror shield or not.

What is the weight of the helmet?

The helmet weighs 260g on its own, and 320g when the mirror shield is attached.

Is the mirror shield replaceable?

Yes, the shield is designed to be user-removable for cleaning or replacement.

Is this helmet suitable for everyday road riding?

While technically safe, its design is optimized for time trials and aggressive racing positions; standard road helmets may offer better ventilation for general riding.

What is X-static fabric?

X-static is a high-performance material woven with silver, providing natural antimicrobial and anti-odor properties.

Troubleshooting

Helmet feels unstable during head movement

Adjust the rear retention dial for a tighter fit and ensure the wide side dividers are positioned just below your ears.

Visor fogging up during use

Ensure the helmet is positioned correctly on your brow to allow proper airflow through the internal channels; avoid blocking vents with hair or headbands.

Internal pads smell or retain moisture

Remove the X-static pads and hand wash them with cold water and mild detergent, then air dry completely.

Pros and Cons

Setup, Compatibility & Care

To ensure optimal performance, start by adjusting the rear retention system and the wide divider straps to achieve a snug, non-shifting fit. When installing or removing the mirror shield, ensure you hold the edges to avoid smudging the optical surface. For cleaning, wipe the shell with a soft, damp cloth and use mild soap for the internal X-static pads. Always store the helmet in the provided premium protective case to prevent deformation or scratches to the shield. Ensure the helmet is stored in a cool, dry place away from direct sunlight when not in use.
