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.
