Bold claim: gravel racing isn’t just a sport about speed—it’s where engineering meets endurance, and Rosa Klöser is proof of that fusion in action. This piece explores how Klöser, the 2024 Unbound Gravel champion, blends science with strategy to push the boundaries of gravel cycling, a discipline that evolves faster than traditional road racing.
Gravel acts as cycling’s laboratory, a proving ground where terrain, rider preference, and a mix of road and mountain-bike tech continually reshape what’s possible. Each race becomes a controlled experiment, and every rider tests a new setup or approach under real-world conditions. Klöser stands out in this environment because she treats bike setup as a principled, research-backed process rather than a mere checklist. Her method is meticulous: every component choice is justified through testing and mechanical reasoning, and each configuration is tailored to the specific demands of the race ahead.
Her precision has powered results beyond Unbound. After clinching the title, she followed with a run of major gravel wins in 2025, including The Rift in Iceland. Yet the core driver of her success isn’t raw leg strength alone; it’s the ability to translate rigorous research into practical equipment decisions that yield real performance gains.
Before the UCI Gravel World Championships in Maastricht, I spoke with Klöser to unpack her equipment philosophy and to consider whether UCI courses truly reflect the essence of gravel racing on the world stage. The discussion also touches on an ongoing identity question for the sport: does the gravel label match the terrain?
The UCI gravel identity debate is loud every year as new courses surface. Maastricht, for instance, drew criticism for a course that felt more like a bike path than challenging gravel—flat segments, hardpack stretches, and light gravel. That undercurrent reflects a broader tension: many fans feel the term "gravel" should evoke rougher terrain seen by recreational riders worldwide. Klöser acknowledges the tension but also points to a larger theme: success in gravel isn’t simply about chasing punishing courses. It’s about efficient use of limited energy—learning what matters when fatigue sets in and prioritizing race tactics, equipment reliability, and rider mindset over pursuit of unattainable perfection.
Her perspective invites a provocative question: as gravel racing continues to professionalize and attract more global attention, will the sport’s governing bodies and event organizers strike a balance between course authenticity and the practical realities of international competition? And for readers and fans, what is your take on whether UCI courses should strive for more “true” gravel or embrace the evolving, hybrid nature of the discipline?
If you’re curious about the full story and the specifics of Klöser’s gear decisions, the article provides detailed examples of how her testing informs tire selection, wheel setup, and on-bike tuning strategies that any aspiring gravel racer can study and adapt.
