Lukas Feth - Alpine Ambition: From the Bavarian Alps to the Front of the Peloton 🇩🇪

From a small village near the Bavarian Alps to the sharp end of elite Zwift racing, Lukas Feth represents everything powerful about the next generation of SISU Racing.

Born and raised in Dettendorf, 50km south of Munich, Lukas grew up surrounded by mountains. Skiing, climbing, bouldering — sport wasn’t optional, it was lifestyle. The mountains shaped him. And eventually, they revealed his strength.

Today, at U23 level, Lukas is one of SISU Racing’s most ambitious and disciplined young riders — a pure climber built for long efforts and high watts per kilo.

Lee Ragsdale: Endurance, Engineering, and Finding SISU Everywhere 🇺🇸

If you’ve ever heard a teammate calmly talking someone through an effort while they’re deep in the red… there’s a good chance you’ve shared a race radio channel with Lee Ragsdale.

Lee is 53 and rides out of Raleigh, North Carolina — a rider built for long days, strong decisions, and the steady belief that endurance isn’t something you “have” - it’s something you build over years. On Zwift and in real life, Lee has become one of SISU Racing’s most recognisable community connectors: the guy who keeps showing up, keeps planning, keeps encouraging, and somehow keeps bumping into SISU kit in the most unexpected places.
