The episode discusses road spray aerodynamics, Argon gas in tires, and the Everest challenge outcomes.

Josh sinks his teeth into questions on turning road spray on a frame into aerodynamic information, Argon gas in tires and deep, carbon wheels for XC mountain bike racing. We also talk about Fatty's successful Everest challenge – the Marginal Gains that worked and the ones that didn't. And we get into some new happenings with Silca.
