The Marginal Gains Podcast, presented by Silca is the show that makes a big deal about the little things, and how those little things...can be a big deal. Josh Poertner of Silca, along with Hottie and Fatty, talks about all aspects of cycling — design, manufacturing, marketing, riding, racing, management and most likely every from a thoughtful perspective. It's a podcast for the thinking cyclist.

We are happy to report that we continue to seek questions Josh is unable to answer, or at least unwilling to try. We regret to announce that we have so far failed, in spite of the fact that in this episode we expanded our universe of acceptable questions to include how to make electric scooters more aero. Josh was, in fact, distressingly excited by…
Jordan Rapp is one of the true greats in triathlon. You may know Jordan as a 5 time Ironman Winner, or maybe as and ITU World Champion.. Or maybe as a US pursuit champion on the track. Nowadays, his claim to fame includes the fact that he designed the Alpe du Zwift (and much more of the gameplay on Zwift, for that matter). Enjoy this episode as Jos…
Josh, Hottie, and Fatty talk about problems in data quality, sampling bias, confirmation bias, cherry picking, and more (including a little detour into baseball). it’s great when data bolsters your beliefs or arguments, but it’s often times way more exciting and enlightening when they don’t!
This was not the episode we intended to create. Josh, Hottie, and Fatty sat down to record an episode on confirmation bias and how it can undercut marginal gains, and instead found that what we want to talk about — and think you might enjoy hearing — is the good things Josh is seeing during a very difficult time. So this is a "stories" episode: sto…

Damon Rinard has been at Cannondale as Engineering Manager for the past five years, but has been immersing himself in bike tech for the better part of three decades. In this episode, Josh and Damon completely nerd out over their shared love of all things technical.
Josh, Hottie, and Fatty are back with all the bike-related questions too nerdy to be asked (or answered) anywhere else. In this episode, we tackle: What lessons from track racing can be applied to singlespeed mountain bike racing? All else being equal, are fewer spokes more aero? Is a matte finish on helmets faster than a gloss finish? What are the…
Cyclists are always on the prowl for marginal gains. We slam our stems, because we've seen pros do it, and they're fast. We eat mounds of spaghetti before races, because we've heard that fast cyclists carbo-load. In many ways, cyclists and cargo cults are remarkably similar. What's a cargo cult, though, and what does it have to do with granola? We'…

James Huang, Global Technical Editor of CyclingTips, is one of the most-trusted cycling journalists in the industry today — and for good reason. He brings a knowledge, experience, humor, and integrity to everything he covers. In this episode, Josh and James have a great, wide-ranging conversation — from their similar histories in getting into the c…
We've got a great batch of questions from you for Josh to contemplate this episode: Does the placebo effect apply to cycling clothes and shoes as well as to equipment? Since many rims are different widths in different places, where should we measure when applying the rule of 105? How much — if any — does a patched tube affect a bike's CRR? Are thir…

You know you've had this suspicion: the core of the cycling industry—much of what it's really selling you—is not tech, speed, or fitness. Nope, the truth is that one of the most powerful marginal gains you'll ever get is thanks to the placebo effect. Josh, Fatty, and Hottie talk about what it is and how potent a force it is in cycling.…
In this Ask-Josh-Anything episode of Marginal Gains, we ask you to imagine Josh as your boy scout leader, and whether that would be the most awesome — or terrifying — thing in the world. (The jury's out on that question by the way). Then we settle in and talk about how Silca's new online Pressure Calculator works, why aero tires are no longer a thi…

We always planned on our Hour Record trilogy being three episodes long. But then Josh got to talking with Robert Chung — one of Josh's intellectual heroes — and we just had to share it. If you think most episodes of the Marginal Gains Podcast are too lightweight and you've been jonesing for a show where Josh has an intellectual equal to talk with (…
We're back with more proof that we're willing to ask Josh practically anything bike-related...and that he's willing to take practically any question seriously. In Ask Josh Anything #008, we talk about what gas you should fill your tires with, the challenge of planning for endurance ride air pressure loss, marginal gains and Kipchoge's sub-2-hr mara…

In this final (?) part of our Hour Record trilogy, we talk about the rules of the modern Hour Record, how marginal gains start really coming into play, the theoretical upper limit for the hour record and how close we are to it, and the future for the hour record. We give extra focus to Bradley Wiggins' hour record, in part because it comes as close…
We're back with a new set of questions for Josh, digging deep into the topics supernerd cyclists care deeply about. We talk about the products that intrigued Josh most at Eurobike, find out what size (diameter and width) he'd make road wheels be if he could start from scratch, speculate on whether the very aero-looking Ceepo Shadow-R is actually ae…

In part 2 of our Hour Record series, Josh, Hottie and Fatty talk about why you can go faster at altitude, even with less oxygen in your lungs...up to a point. We chat about the magnificently weird (but mostly magnificent) Merckx hour record, and how much further he might have gone if he knew then what we know now. Finally, we discuss the cyclists (…
The ongoing "Ask Josh Anything" series is back from Summer vacation and we've got a fun — and surprisingly informative — set of questions for Josh, including: What marginal gains are made by following the TTT instructions in a pre-TdF video by Team EF? When you've got a tailwind, is it better to still make yourself as small as possible, or should y…

The Hour Record is unlike any other race in cycling. Almost unimaginably difficult to do, but elegantly simple in concept: Ride your bike, as hard as you can, for an hour. When you look underneath this simplicity, however, the subtlety, beauty, cruelty, and sophistication of this race become totally gripping. And then you find out there's way, WAY …
With two of the three of the Marginal Gains hosts also doing a weekly podcast on the Leadville 100 MTB race, you knew it was just a matter of time 'til we dragged the topic of Leadville into this show. And that time...is now. The fact is, the idea of marginal gains goes hand in hand with endurance races like the Leadville 100. It’s over long days i…

Josh is in Europe, involved with some race or something. Whatever. Which means that Hottie andFat Fatty get to pick the topic for the episode. And that means fewer big words and more talk about a topic Hottie and Fatty have wanted to dig into since episode 1 of Marginal Gains: the process of creating and refining products at Silca. Joining them is …
In this Q&A episode of the show that makes a big deal about the little things (and how those little things can be a big deal), we try to stump Josh with questions like: Do stiff shoes matter? What's the point of hookless rims? What benefits does steel have over carbon? What's the weight vs aero tipping point? Are 23mm tires dead? Is graphene tire c…
"Materials and Marginal Gains" is a big topic — too big for a single episode of this show. So if it's OK with you (and we think it will be), we'd like you to think of this as the first of many episodes about Materials. And we're going to kick this introduction off with a few stories, and look forward to hearing your thoughts and feedback...which we…
We didn't set out to turn every other episode of the Marginal Gains Podcast into the "Try to Stump Josh" game show, but at least 2/3 of the hosts of the show are glad it worked out this way. In this episode, we ask Josh what he thinks of Zipp's new MTB rims, puzzle over why the GoPro is so non-aero (and how to mitigate that non-aero-ness), discuss …
While we have just 5 contact points with the bike, each of those contact points are made of whole systems of contact points. And your tires are the ONLY contact points between the bicycle and the earth. Think about it: all the forces, traction, braking, cornering, all have to be transferred through tiny patches of rubber, dynamically moving on the …
We didn't necessarily intend for it to turn out this way, but this episode of Marginal Gains' "Ask Josh Anything" is a wheels, rims, tubes, and tires question extravaganza. We also find time to discuss the Silca Hiro chuck's origin story, whether testing how aero helmets are in a lab setting has real value, and exactly how much impact on your ride …
Hysteresis is the term for processes that behave differently in one direction than in another. Understanding it is critical for flying, for dampened suspension systems, and for being aero on your bike. Yep, in this episode we'll be making liberal use of analogies that include a Tempurpedic mattress, a rolling tire, mountain bike suspension and a fa…
In this Q&A episode of Marginal Gains, Josh answers questions about whether front and rear tires should have symmetric or asymmetric air pressure (and why). We dig into whether no-name Chinese handlebars and wheels are a good deal, or just cheap (and why). Josh analyzes the ongoing thread at Slowtwitch that shows little Crr difference between 23, 2…
Non-linearity has literally has won and lost the Tour de France. Josh breaks down this important concept -- one he admits to sometimes having a tough time wrapping his brain around. The metaphor? Extreme betting during what would turn out to be a very expensive round of golf. From there we apply non-linearity to cycling and aerodynamics. Let's just…
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, technique…

We love symmetry—our eyes are drawn to it and our minds intuitively grasp it. But in this episode, Josh, Hottie and Fatty look at asymmetry, what it is, what it means, and how it can be leveraged for a competitive advantage in complex cycling problems where there isn't an obvious or easy solution. Then we'll bring it all home with some very practic…
