It's an Ask Josh Anything episode! We talk about The Rule of 105, the extent to which "bigger is better" is true for fairings, whether tire inserts need to be factored in when using air pressure calculators, why you might get conflicting recommendations from different air pressure calculators, how many watts a slow-turning old derailleur cog might cost you, the challenges a hot day might bring to your waxed chain, and more. So much more. Some people might say too much more, but we are not those people, and we're betting you are not either. Don't miss this episode, and keep your questions coming!

At this point we've lost track on how many episodes we've dedicated to wind tunnels, but this is at least partially one of them. We've also got great questions about Fatty's new Firefly and the Ti-printed parts Silca created for it, a classic question on the best body position for riding in a strong tailwind, axle handle alignment, and a remarkably well-considered question on calculating tire pressure for full-suspension bikes.

Gravel Racing has gone global, and governing bodies have gotten involved. The UCI is now in its third year of putting on its Gravel World Series. It has more than two dozen races on four continents. Instead of running the series itself, the UCI has turn to a sports group and the point person in that group is three-time Cyclocross World Champ Erwin Vervecken. It's an understatement to say he knows drop bars and dirt. He is. We talk to Erwin about how the series began, the lack of a major presence in the US, how to get into Worlds, UCI rules and Gravel, and we throw in some Cross questions.

John Cobb may be best known for his bike saddles, but his experience and innovation go much deeper. John may be the first person to take a bike to the wind tunnel, and is likely the only person to crank up the tunnel to 70mph...with a rider in it. Enjoy this great episode with a cycling innovator

Life Time puts on what is arguably the biggest and most important pro bike racing series in the US: The Life Time Grand Prix. And one man is in chage of it all: Kimo Seymour. Fatty and Hottie talk with Kimo changes in the race, the "Call of a Life Time" series, aerobars, Keegan's Swenson's chances for dominating the event for a third year running, and much more.
