Non-linearity has literally has won and lost the Tour de France. Josh breaks down this important concept -- one he admits to sometimes having a tough time wrapping his brain around. The metaphor? Extreme betting during what would turn out to be a very expensive round of golf. 

From there we apply non-linearity to cycling and aerodynamics. Let's just say that after this episode, you will give serious consideration to shaving your head. 

It's the first of what is sure to be many "Ask Josh Anything" episodes of the Marginal Gains podcast. And if this episode is any indicator of how our listeners think, the Marginal Gains crowd is a smart bunch of cyclists. Josh answers questions about experimenting to get your tires to the right pressure, tire vs frame and fork compliance, techniques for getting more aero when you don't have a wind tunnel, marginal gains vs diminishing returns, rim vs disc brakes, lube preferences, and more. Much more, actually.

We love symmetry—our eyes are drawn to it and our minds intuitively grasp it. But in this episode, Josh, Hottie and Fatty look at asymmetry, what it is, what it means, and how it can be leveraged for a competitive advantage in complex cycling problems where there isn't an obvious or easy solution. Then we'll bring it all home with some very practical advice on what all this should mean to you the next time you set your tires' pressure. 

Welcome to the first episode of The Marginal Gains Podcast, presented by Silca — the show that makes a big deal about the little things, and how those little things can be a big deal. 

In this first episode, Josh Poertner, Hottie (Michael Hotten) and Fatty (Elden Nelson) obsess over about what marginal gains are, why they matter, and the huge difference Josh has seen them make in building bike components, in pro cycling teams' success, and even outside the cycling world altogether. 

It's a show for the thinking cyclist. Enjoy Marginal Gains!
