Real-world testing shows suspension forks might flip the script in the gravel v MTB tyre debate.
What happens when you bring WorldTour-level testing rigour to gravel? In this episode of Performance Process, Ronan sits down with performance engineer Marc Graveline to unpack a surprising result from two intensive testing blocks with pro rider Hannah Shell in the run-up to Unbound.
Using drag sensors, IMUs, and a structured testing protocol, Graveline found that 40 mm gravel tyres paired with a suspension fork outperformed even wide MTB tyres, overturning one of gravel racing’s biggest equipment trends of the past two years.
They dig into tyre pressure, terrain interaction, the importance of system thinking, and how optimisation on rough roads demands a rethink of conventional aero priorities. This one’s about more than just tyres—it’s about changing how we think about speed on gravel.
