He is currently considered as the most successful cyclist in Switzerland. Stefan Küng (29), born in Wilen in Thurgau, is at home at the top of the world. The world’s best also includes the young Wattwil-based brand react, which is now entering into a partnership with the exceptional talent. With its innovative ShadeTronic® technology, which was launched in June 2022, react is revolutionizing the sports eyewear market. Their optray sports glasses are not only lightweight, weighting just 36 grams of high-performance polymer, they are energy self-sufficient and adapt to changing lighting conditions within 0.1 seconds – thanks to an LCD coating on the lenses and photocells in the nose bridge. The perfect conditions for both players to excel in bike racing.

“I am excited to have found a sponsor in react who, like me, puts their heart into everything they do and outgrow themselves with every new challenge. With this partnership, I can visualize my ambitious goals for the upcoming cycling season” says Stefan Küng. With its commitment, react reaffirms its expertise in the sports eyewear market. “Our optray sports glasses are great for cycling,” says react CEO Patrick McDermott. “Our partnership with Stefan Küng underlines the added value of our products for cyclists.”

At the beginning of his career, it was about a fascination for the interaction between man and machine. The human being who can be a machine – a thought that never let go of Stefan Küng and made him enter cycling. Since 2013, the professional cyclist competes in the elite. His current team: Team Groupama – FDJ. The multiple World Championship medalist and Olympic winner is one of the strongest racers with German mother tongue. He has won three World Championship medals in the last five years (silver in Australia in 2022, bronze in Imola, Italy, in 2020 and bronze in England in 2019).
