Marginal Gains Scorecard with Dylan Johnson

Marginal Gains Cycling Podcast, Presented by Silca ·

2024/11/23

Dylan Johnson is back with a follow up to the testing he and Josh did in the spring. The race season started with the two of them in the wind tunnel looking for Marginal Gains that could be used in the Lifetime Grand Prix and the other off-road races Dylan had on his calendar. Dylan reports back with his "on-course" experience and a look at how other racers are adopting some of the advantages he and Josh first discovered. Dylan also has questions for Josh on how some of the new "finds" and Silca

2024/11/12

Is it a coincidence that Fatty picked all the questions for this episode, and that all the questions in this episode are topics Fatty finds either interesting or personally relevant? Probably not! But if you're wondering if chain waxing makes sense for dusty trail conditions, are curious how much (if any) the outside temperature should affect your tire pressure, or are wondering how inflexible cyclists should set their bikes to be as aero as possible, you'll find Josh's answers as intriguing as

Zwift & Marginal Gains, with Zwift Product VP Mark Cote

Marginal Gains Cycling Podcast, Presented by Silca ·

2024/10/28

Zwift VP of Product Mark Cote joins the Marginal Gains crew, picking up where we left off in our last conversation: the wind tunnel. This time, his time in the tunnel is all about future-looking features for Zwift, and this peek at what's to come is not to be missed. From there we talk about everything in the present and future state of Zwift and Marginal Gains, from the extremely practical (tips and warnings for your own Zwift setup) to the philosophical (is Zwift for racing, training, or fun?)

Bryan Larsen tells us his only real talent is that he's too dumb to quit. We strongly disagree, but take his point: Bryan is no quitter. In this episode, Bryan talks us through how he took the constraints given to him through birth and accident, and used passion, perseverence, and a love of marginal gains to reinvent his racing career.

Marginal Gains Cycling Podcast, Presented by Silca ·

2024/08/05

We're so excited to kick this 35th episode of our "Ask Josh Anything" series with a discussion of the announcement of Silca's partnership with Visma Lease-A-Bike. Fatty does his level best to pitch having Hottie in the team car, hot-waxing on the move. We move from there to the challenges of high pressure with hookless rims, and how it has put Josh in the position of being the PSI bartender and cutting pressure-thirsty riders off. And that's just for starters. We also get into group ride marginal

Amy Charity and SBT GRVL

Marginal Gains Cycling Podcast, Presented by Silca ·

2024/07/05

Gravel Racing is moving face and Amy Charity is one of the movers. Amy is the founder of SBT GRVL in Steamboat Springs, Colorado. The race started on the back of a napkin in 2018 and has quickly become one of the premiere off-road events in the U.S. After a few short years of success, Amy expanded SBT to Europe and Australia. But before the dirt roads, Amy raced on tarmac. She was a pro roadie with a short but successful career. And before road racing, Amy was in high finance. Josh and Hottie talk

2024/06/03

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.

Erwin Vervecken and the UCI Global Gravel Series

Marginal Gains Cycling Podcast, Presented by Silca ·

2024/05/21

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

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

Marginal Gains Cycling Podcast, Presented by Silca ·

2024/02/23

Our recent wind tunnel episodes have triggered a LOT of aero questions from our listeners, and Josh -- with hand hovering over the "It Depends" button -- takes them on. From IRL Burrito Powerups (IYKYK) to the StripChip and the Chain Waxing System to aero chainrings to leg hair stubble as a potential aero advantage to shoe aerodynamics, Josh will — apparently — answer anything.

Josh answers more of Fatty & Hottie's pressing questions about the surprises people are in for when visiting a wind tunnel for the first time, what happens when key learnings from a wind tunnel session are ignored, how often follow-up questions triggered by a wind tunnel session are actually followed up on, whether it's worth it to bring anyone but a top-pro into the wind tunnel, how bike companies twist wind tunnel results, and much more.

During his tenure at the Big S, he convinced the powers that be that the Big S needed its own wind tunnel — an amazing story Mark shares with Josh.

Ask Josh Anything...About Wind Tunnels (Part 1)

2023/12/18

Josh's experiences in wind tunnels have come up in dozens of episodes of Marginal Gains, and we always find ourselves with more questions. In this episode, we're finally giving ourselves permission to ask them, from the essentials of using a wind tunnel to a day in the life before, during, and after testing in a windtunnel. Look, we'll be honest here: we brought way more questions to this conversation than Josh had time to answer, and at some point during the recording, we realized we weren't

Would your motorcycle chain benefit from an afternoon in the chain wax spa? If you use a gel packet as an improvised tire boot, how much will it affect your bike's performance? When using the Rule of 105, should you be using the rim width at the brake track, or the widest point of the rim as your measurement? And for those of us carrying lunch, clothes, and a computer to the office as we commute by bike, how can we be more aero? Josh bravely answers all these questions...and for one of them, even
