Stage races Sepp Kuss (born September 13, 1994) is an American professional cyclist from Durango, Colorado.

A talented climber, he has played a crucial role in helping team leaders Primož Roglič and Jonas Vingegaard secure a combined six Grand Tour victories.

[10] Throughout his career, Kuss has also achieved individual success, winning stages at both the Tour de France and Vuelta a España.

Kuss started out in mountain bike racing as a junior and as a student at the University of Colorado Boulder, where he won three national titles at the Collegiate championships in XC (2014 and 2015) and Short Track (2014).

[23] During the first two weeks of the 2022 Tour de France he rode in support of Roglič, Vingegaard, and Wout Van Aert as the team sought stage wins and to challenge defending champion Tadej Pogačar for the Yellow Jersey, both of which they were successful in doing.

[24] He shepherded Vingegaard up Hautacam, the final HC climb, as he had done for Roglič so many times in other grand tours, until the Dane attacked and tightened his grip on the race.

The team was so successful that they held the yellow, green and polka dot jerseys as the race neared its end, and won them.

[25] Kuss rode in support of Roglič's victory in the 2023 Giro d'Italia and Vingegaard's win in the 2023 Tour de France.

[28][29] In 2024, Kuss was originally named in the team list for the 2024 Tour de France, but was scratched before the race began due to a Covid infection.
