Getting AiRO with Ingmar Jungnickel
Marginal Gains Cycling Podcast, Presented by Silca
For most of us getting into a wind tunnel is but a dream. Tunnels are hard to find and harder to afford. As an alternative Josh has recommended the Chung Method. It's proven yet it does take some expertise to get right. What if there were something in the middle? Something that is more accessible and less expensive than a wind tunnel yet doesn't require the hours of commitment and trial and error of field testing? Our guest believes he has just that. AiRO may sound like a company that is trying to latch onto the "AI" craze. But its founder, Ingmar Jungnickel, has been into cycling...

AJA #47: Aluminum Velodromes, Forever Chemicals, Big-Wheel Aesthetics, and valve stem nerdery
Marginal Gains Cycling Podcast, Presented by Silca
This Ask Josh Anything grab-bag starts with Tucson’s new aluminum velodrome, evolves (devolves?) into altitude hacks for hour records, “no-rules” speed dreams, and holiday gift picks. From buying a kid’s first bike (and why chain waxing might be the cleanest parenting win) to ESG-minded shop habits, Roubaix wheel diameter fever dreams to, aero brake-hose routing, and the Clik Valve debate—this episode covers the weird, practical, and wildly opinionated. Happy Holidays!

Fatty sits down with 2024 Leadville champion (and his daughter) Melisa Rollins to discuss her meteoric rise from riding borrowed bikes to the professional peloton.

AJA #46: Safety Pins, TPU Wins & Indoor Suffering
Marginal Gains Cycling Podcast, Presented by Silca
Josh tackles why we’re still pinning race numbers instead of printing them on jerseys, then dives into the tech story behind Silca’s translucent TPU tubes. We talk about real-world marginal gains for everyday riders, and Fatty's recommendations for indoor training setups. Last but not least, you do NOT want to miss Josh’s unfiltered take on the UCI–SRAM 10-tooth cog controversy.

32er Test Ride with Daniel Yang
Marginal Gains Cycling Podcast, Presented by Silca
We rarely chase trends or product announcements on the Marginal Gains Podcast. The news of the day we mostly leave to other shows. So allow us while we make an exception to our normal behavior and take a stab at the 32 inch wheel. The wheel size is not the new thing here. It's the tire that's creating some buzz. A viable, tubeless mountain bike tire to be precise. When Maxxis started showing its 32 inch Aspen, bike builders took notice. Some fired up their CAD programs to see if they could make it work. Using heat and steel, drawings were then turned into something rideable. One of those...

AJA #45: Pump Accuracy & Cheap Carbon Parts
Marginal Gains Cycling Podcast, Presented by Silca
Hear why that “psst” when you pull the chuck is just hose air (not lost PSI), how to set smarter pressures for tandems and “big-butt” weight splits using a bathroom scale, and what tread actually grips on loose-over-hard. Josh also demystifies analog vs. digital gauge accuracy (and drift) and tackles the carbon-on-the-cheap question—when a bargain is fine, and when it’s a dentist bill waiting to happen.

Best Bike Split Founder Ryan Cooper
Marginal Gains Cycling Podcast, Presented by Silca
Marginal Gainers are familiar with Best Bike Split -- the website where using rider data you can forecast a finish time on a specific course. It has been a great tool for years for amateurs and pros alike. Josh has frequently referenced BBS on the show. Fatty and Hottie have discussed it on their Leadville Podcast. But we wanted to know what is under the hood. For that we turn to its founder Ryan Cooper. Before Best Bike Split, Ryan was a lot like us: a competitor with the hopes of going faster. Unlike most of us, he's really good at math. His ability to come up with equations and sus out...

Marginal Gains Cycling Podcast, Presented by Silca

3X Natl Champ Lauren Stephens
Marginal Gains Cycling Podcast, Presented by Silca
Lauren Stephens has been easy to spot in both Road and Gravel events; just look for the stars and stripes. She has won three US titles: two gravel and one road. Oh, but there's so much more to her career. How about more than 30 UCI road race victories? She has twice won the Joe Martin Stage Race, the Tour of the Gila and Unbound 100. Lauren has also raced Track, Time Trials, Mountain Bike and Cyclocross. Not bad for a former high school math teacher who wasn't a serious cyclist until 2008. In addition to reviewing her career, Josh and Hottie also talk to Lauren about her nicknames, her...
info_outlineBehind every great cyclist is a great bike fit, which means a great bike fitter. Honestly, we're not sure it’s possible to overstate the gains — or losses— a bike fit can bring. And a startling number of top pros we’ve had on this show trust Barry Anderson of Cyclologic, in Scottsdale Arizona. Barry has popped up on our radar numerous times and for numerous reasons recently. We're excited to share Barry's practical guidance on the why, how, and who of a great bike fit.
