AJA 23: Tubeless Sealant Deep-Dive
Silca has a new tubeless tire sealant out, and Hottie and Fatty have some questions about it. A whole hour's-worth of questions, in fact. From the recycling aspect of it to setup strategies to keeping carbon fiber from clogging your valve stem, this is the episode that shows what happens when Josh starts thinking about plugging up holes.

Andy Hampsten Part 2: Giro d' Italia, Eddy Merckx, and Bike Touring
Part 2 of our chat with Andy Hampsten picks up right where we left off in part 1: With Hampsten in the Maglia Rosa. Andy finishes this incredible story, and from there we get into a wide range of topics with this iconic cyclist: Cinghiale Tours, Titanium bikes, Eddy Merckx, "Huffy" bikes, and much more.

Bike Club NFT
The Bike club has been operating under the same model for years -- decades. Bike Club NFT seeks to change that by turning memberships into digital assets. Some things under the old model are still true but as Josh finds out, Bike Club NFT has some new twists too.

Andy Hampsten and Marginal Gains
Possibly the nicest living cycling legend, the one and only Andy Hampsten joins Josh to talk both about the early days of his career and to give an account of what is easily one of the most extraordinary performances ever in cycling: Andy's unbelievable day on the Gavia in the 1988 Giro D' Italia.

Canadian Road Champ Guillaume Boivin and Marginal Gains
If you saw Paris Roubaix this year, there's a good chance you saw our guest — Candadian Road Champ Guillaume Boivin — in action. And thanks to the laws of supply and demand (Guillaume needed a chain, and Hottie had a Silca Hot-Waxed Chain available), we were able to nab this interview with this road star about how "G" (as his Istrael StartUp Nation teammates call him) started biking, his fixation on bike tech, and his very intense day at Paris Roubaix.

Lennard Zinn and Marginal Gains
If you are a student of cycling — and the fact that you listen to this show means you are — you have no doubt read a fair amount of Lennard Zinn's work, from books to being the tech editor at VeloNews, Zinn has written thousands of pages about cycling. And in this episode, he joins Josh to talk about his days as a skier, how he got talked into writing books, Hopf Bifurcation and bike shimmy, rolling resistance and Lennard's latest venture: E-bikes. We guarantee you're going to love this thinking cyclists' conversation.

AJA #22: Summer Vs Winter, Tubes Vs Tubeless, Track Vs Road
A wheel builder wants Josh's thoughts on the difference between road and track rims. A soon-to-be-worldtour-racing pro wants to know whether the sluggishness he senses in tubeless tires is all in his head. A gravel racer wants to know how to justify the purchase of a second set of wheels to his wife. And of course, the saga of hypotheticals continues as a listener asks what Josh would do if he were suddenly the Tech Director of the UCI. As always, it's a wide-ranging episode of Marginal Gains...and you will not want to miss it.

The Weight Weenie Episode
There was a time when weight was thought of as the most important — if not only — consideration for more speed. That's obviously no longer the case, but weight does still matter. In this episode, we look at when, where, and how much weight matters. If you've ever hoisted a bike to get a sense of how much it weighs (yes, that's all of you), you will not want to miss this episode of Marginal Gains.

AJA #21:Pressure, Lube, & Trips in Time Machines
It's a rainy, muddy, sloppy, gritty day at the Paris-Roubaix, and you're a pro team's race director. What chain treatment do you go with? You have the option to swap bikes on the course; are the watts you gain with a clean drivetrain worth the cost in time lost in bike transfer? What's the tire pressure you should run...and should you tell the truth if anyone asks? We get into all this, more, and the ways bikes will change 50 years from now, as we Ask Josh Anything in the Marginal Gains Podcast.
