Extended Product Information

FAQs

Does the helmet come with the visor?

Yes, the HJC Adwatt includes an integrated mirror shield for improved aerodynamics and clarity.

Can I use this helmet for regular road cycling?

While it can be used for road cycling, it is specifically optimized for aerodynamic efficiency in time trial positions and may not provide the same level of ventilation as a dedicated road helmet.

What is the weight of the helmet?

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

How should I clean the mirror shield?

Clean the shield using a soft microfiber cloth and lukewarm water. Avoid using harsh chemicals or abrasive materials that could damage the mirror coating.

Is the helmet adjustable?

Yes, it features an integrated retention system that allows for a precise fit adjustment at the back of the head.

What is included in the box?

The box includes the HJC Adwatt helmet, the integrated mirror shield, and a premium protective carrying case.

Troubleshooting

Shield fogs up during the ride

Ensure your riding position allows enough airflow through the front vents to maintain constant circulation across the interior of the shield.

Helmet feels loose or unstable

Adjust the rear retention dial while wearing the helmet to ensure a snug fit around the occipital bone, then check that the chin straps are tensioned correctly.

Internal pads retain moisture

Remove the X-static pads and hand wash them in lukewarm water with a mild detergent, then air dry them completely before re-installing.

Pros and Cons

Pros

Race-proven aerodynamics used by world-class professional teams
Lightweight construction at only 260g (without shield)
Effective cooling even at high speeds due to Venturi design
Includes a premium protective carry case

Cons

Specifically optimized for time trial positions, which may feel different than standard road helmets
Limited ventilation compared to standard road-specific helmets
Visibility with the integrated shield may require acclimatization

Setup, Compatibility & Care

To ensure optimal performance, adjust the retention system while in your standard riding position to prevent the helmet from shifting. When handling the integrated mirror shield, always use a microfiber cloth to avoid scratching the reflective coating. Store the helmet in the provided protective case when not in use to maintain the integrity of the shell. Periodically inspect the X-static pads and wash them by hand with mild soap and water to ensure the antimicrobial properties remain effective. Ensure the shield is securely clicked into place before starting your ride to prevent rattling at high speeds.
