HJC ADWATT – a helmet built for maximum speed.
The HJC ADWATT is a time-trial helmet designed for cyclists who count every second. Developed through years of aerodynamic tunnel testing and trials with professional track riders, it minimizes air resistance while ensuring comfort and safety, even at the highest speeds.
The specially contoured shell and optimized shape are engineered for the smoothest possible airflow.
ADWATT allows riders to maintain an aerodynamic position without compromising ventilation – its advanced channel system effectively dissipates excess heat, which is crucial during intense efforts.
Inside, the helmet features advanced antibacterial padding that can be easily removed and washed. The fitting system ensures a secure, customized fit for maximum stability, safety, and comfort throughout the ride.
The ADWATT was perfected through advanced wind tunnel testing to enhance aerodynamic efficiency on the track. In April 2019, using the HJC ADWATT time-trial helmet, Victor Campenaerts and the LOTTO SOUDAL UCI World Team broke the UCI Hour Record on the velodrome.
The HJC ADWATT is the ultimate choice for riders striving for every fraction of a second – both on the track and in individual time trials.
