The Adwatt was designed through enhanced wind tunnel testing to improve its drag force performance on the track. Using the HJC ADWATT time trial helmet, Victor Campenaerts and the LOTTO SOUDAL UCI World tour team beat the UCI HOUR RECORD in April 2019.

Specifications

Sizing
  • XS / S 54-56 cm 21.2-22”
  • M / L 57-59 cm 22.4-23.2”
  • XL / XXL 60-63 cm 23.6-24.8”

This helmet has 2 vents and weights about 280g without its shield, or 340g with its shield. HJC Successfully took up the challenge of developing an Aero helmet which is efficient both with and without a shield, creating a helmet that is fast and extra ventilated at the same time.

This helmet comes with spare pads, wash bag and a premium case to protect the helmet and its shield when you travel.

Technical features

Wind Tunnel Tested

HJC helmets are tested in the laboratory as well as in “real-life” to meet the highest quality standards. HJC is one of the very few helmet companies equipped with its own state-of-the-art wind tunnel laboratory to test aerodynamics, ventilation, noise, and more. The HJC wind tunnel test lab measures the air forces in a variety of riding conditions to improve helmet performance.

Aerodynamic Design

Coming from MotoGP race-helmet design experience, HJC designers and engineers have become experts in aerodynamics and wind ventilated helmets. Aero helmets, as the word implies, are more aerodynamic than the conventional racing bike helmet, but with compromised ventilation performance. With HJC Helmets, this compromise is very much reduced. HJC offers probably the best ventilated semi-aero helmet on the market…. Save Watts with HJC Helmets!

Ventury Dynamics

In order to achieve maximum ventilation, a technical adaptation of Bernoulli’s principle is applied to HJC’s aerodynamically enhanced models. In motion, the rate of surface flow generally increases as it progresses towards the rear of the helmet. Through pressure differences, cool air from the frontal intake is extracted through the rear vent for internal heat dissipation, giving the cyclist optimum ventilation and perfect air flow while riding.

In-Mold Construction

In-mold is a method consisting in bonding the EPS together with the outer polycarbonate shell for greater structural strength. This improves the rider’s protection by providing a compact reinforcement and gives the product a perfect finish.

Internal Reinforcement Structure

The helmets are reinforced with an internal frame integrated into the EPS, the skeletal frame not only holds the helmet in one piece, but also makes it stronger and more resistant to protect your head in the event of a collision.

Feather Light

HJC bicycle helmets are designed and engineered through precise measures to have the lightest weight possible. Density, placement, shapes and materials all play a part in weight optimization.
