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.

Plus why modern bikes require more frequent headset inspections, Ridley’s new gravel bike, and a tonne more.

It’s a big episode this week as the geeks, Dave and Brad, cover a whole lot of ground including the latest new products, a rant on silly-priced items, a little on chain wear, why headset inspections matter more than ever, and there’s an in-depth chat with a true geek of the wheel building world.That opening chat related to chains comes off a recent Threaded article about chain wear.

Meanwhile, Dave jumps on a call with wheel build extraordinaire Tristan Thomas of WheelWorks to answer a multi-part Ask a Wrench question. It quickly gets detailed and geeky, but we figured that’s exactly what you’re here for.As a reminder, the Geek Warning podcast is only made possible through members of Escape Collective.

Plus why tyres are likely to keep getting wider.

With the road season soon to come to a close, the events in the tech world are unsurprisingly more focused on the dirt. In this week’s episode of Geek Warning, you’ll hear Brad and Dave cover the latest in tech across road, gravel, and mountain bike.

Amongst a number of new things, the geeks discuss a future of electronic suspension and what that could spell for the gravel world.
