    Hi Josh, next to tyre width I was wondering what pros use to fill their tyres. Did anyone bother experimenting with lighter gas such as helium or 100% nitrogen for less pressure loss over time? Maybe we’re taking too marginal to bother?

    You are so awesome! I don’t believe I have read anything like that before. So great to find somebody with genuine thoughts on this subject matter. Really.. many thanks for starting this up. This website is one thing that’s needed on the internet, someone with a little originality!

    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.
