Description

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.


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.
