Sea Otter Pt. 1 - Hooked on Road Wheels

We're not afraid to share an opinion on this show. At no time was that more apparent then when Josh let his thoughts known about hookless road wheels. It caused a bit of a reaction in the industry to say the least. And while we have some firm beliefs on certain technologies, we also believe in fairness. Which is why at Sea Otter we gave some wheel brands a platform to explain what has become a somewhat divisive topic.  Our guests work for three brands: ENVE, CADEX and Mavic. Two of them stand behind road hookless as a high performance and safe feature. The third has stuck with hooked rims. All three bring a unique perspective on what it takes to secure a tire to a wheel. We also talk to these wheel makers about their brands as a whole: what's driving innovation, how pro peloton success turns into sales and for one of them, what it takes to revive a heritage brand.  

It feels like now more than ever it is important to find sources of information and reporting that are trustworthy. It used to be fairly easy: subscribe to a credible outlet and trust that said newspaper or magazine would have guardrails in place to get it right and to exercise fairness. As the internet and social media became the predominant sources we rely on, a lot of those guardrails were knocked down. It could be argued that the system in place now is more democratic. More wide open. More voices. But along the way the trust factor has taken a blow.  That's why we wanted to talk to Ben Delaney. Ben came from the old school ways of cycling reporting. He got a degree in journalism. He got a job at a magazine. He did the work and made his way up. Like a lot of his colleagues, he also took his lumps as traditional outlets succumbed to the pressures of lower ad revenues and tighter budgets. After being let go more than once by Velo, Ben decided to go solo.  These days you can find Ben making videos for his gravel focused "The Ride" YouTube channel. It's one of Josh's favorites, so much so that Silca supports the channel. "The Ride" is a great place to check the latest in dropbar, offroad tech and trends. But this interview is less about gear and much more about the landscape of cycling media. How it got to where it is and what it needs to keep its credibility. 

Josh has spoken on many occasions about his time with Zipp. The engineering. The R&D. The wins. The fails. Josh was part of a team that changed the scene, both for pro and amateur racers.  At the head of that team was Andy Ording. Andy took over Zipp from Leigh Sargent in 1998 and guided it through its glory days that Josh is so fond of. Andy's journey to carbon wheels is far from linear. A native of South Africa, he eventually found his way to the states via motorcycles. Andy's strengths are in sales and logistics and those strengths eventually led him to the bike industry. In this episode, Andy and Josh swap Zipp stories. They also share insights on what it takes to foster new ideas. How empowering people is one of the keys to making the next great Marginal Gain. 

Fatty drops a bombshell: he's turning 60 and attempting an Everesting challenge this June — and he needs Josh and Hottie to marginal-gain every aspect of the ride. From course selection and bike setup to tire choice, chain wax strategy, pacing by heart rate, and why a leaf blower might be his secret weapon, the crew breaks down how to get a self-described "card-carrying AARP member with a paunch" up 29,029 feet of climbing on a decade-old bike.

Most of us hardly give those water bottles in our cages a second thought. It's plastic. It's there. It's got what we need. But in the late 20-teens, Carina Hamel and her partner started giving those bidons and second thought. And a third. And a fourth. And like a lot of new ideas, they thought, "There's got to be a better way." Their critical thinking led them to develop Bivo Bottles: stainless steel bottles that fit properly in bike cages.  Since late 2020, Bivo has been trying to convince cyclists that they are better off with a metal bottle than plastic. They've made progress but the ride has  not been smooth. First came Covid, which delayed their launch and stalled their grassroots marketing campaign. Then just as they started getting  momentum, along came massive tariffs which threatened to end Bivo altogether.  But Bivo is still here and as of this episode, celebrating a five year anniversary. We talk to co-founder Carina Hamel about their ideas, innovations and a chance run in with a NASA engineer. 

Josh answers listener questions about essential race-day gear, from what to pack for Cape Epic to whether digital torque wrenches are worth the beeping. We into Lifetime's controversial drop bar ban at Leadville, exploring whether safety concerns justify the change and what aero options remain for marginal gainers. 

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 aerodynamics long before Chat GPT became a thing. He has a degree in engineering, he's developed on-bike aero hardware, and he worked for Specialized where he logged many hours in that company's wind tunnel. All of that, along with a chance opportunity to work with speed skaters, led him to develop a CFD program that attempts to make cycling aerodynamics more accessible.  Ingmar's back story includes meeting are own Josh Poertner. But the real story here is how good Computational Fluid Dynamics has become. The potential of AiRO and its data even blew the mind of Josh as you will hear in this episode of Marginal Gains. 

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. Joined by fitter Barry Anderson, they dig into the biomechanical challenges of world-class power, the dangers of athletic stoicism, and the chaotic reality of stage racing in Africa.

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.
