Gold went to France’s Arthur Longo – his first ever World Cup victory – while silver was taken by Canada’s Justin Lamourex.
Finland’s Janne Korpi and Antti Autti as well as Japan’s Kazuhiro Kokubo, who occupy the top three positions in the overall standings, were not in attendance.
Meanwhile, in the women’s event, gold went to Zhifeng Sun of China as she edged out compatriot Xuetong Cai, while Australia’s Holly Crawford collected bronze.
