In this episode of Performance Process, Ronan and Caley welcome Dylan Johnson, a lifetime Gran Prix athlete, coach, and data-driven performance-optimising YouTuber, to discuss the ins and outs of off-road racing. Dylan shares his insights on the category he arguably reignited: drop bar mountain bikes, exploring the whys and the pros and cons of ditching flat bars. He also delves into tyre selection, revealing his two tyres for gravel racing following his own rolling resistance and aero testing. Speaking of aero testing, Dylan discusses the importance of aerodynamics in gravel racing, and his advice on where to optimise first. Finally, as gravel racing continues to evolve, the group discuss if current trends are truly optimal or stop gaps along the way with predictions on the future of bike design. Whether you’re a racer or an enthusiast, this episode is packed with practical insights and inspiration for the gravel and off-road rider.
