Best Bike Split Founder Ryan Cooper

Marginal Gains Cycling Podcast, Presented by Silca ·

2025/09/22

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

3X Natl Champ Lauren Stephens

Marginal Gains Cycling Podcast, Presented by Silca ·

2025/08/01

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

AJA #43: CRR/CDA and Hookless plus The Magnus Effect

Marginal Gains Cycling Podcast, Presented by Silca ·

2025/07/11

We take a look at what has become a dilemma for some Marginal Gains seekers and that is optimizing aero, rolling resistance on a tubeless, hookless rim. Josh has an admittedly unpopular take on the subject. We also get into the aerodymanic idea known as the Magnus Effect. The principle says that a spinning object will develop unequal pressure on either side as it moves throught air. Josh expains how -- if at all -- the Magnus Effect, affects that rotating thing we love; the bicycle wheel. We

AJA #42: Pipe Cleaners and Crack Baggies

Marginal Gains Cycling Podcast, Presented by Silca ·

2025/06/27

We know, the title sounds like we're doing an episode about drug paraphernalia, but trust us, it's the (very good) answer to one of many great questions posed to Josh in this latest listener-driven Q&A episode. We get into using the right lube under the right conditions (including super dry moondust mountain biking), aero combos with the Conti Aero 111, TPU tube challenges, and much more. It's a fun and info-packed episode from the show that dares to say, "It depends."

The Marginal — and maximal — gains of a great bike fit

Marginal Gains Cycling Podcast, Presented by Silca ·

2025/06/09

Behind 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.

Cécile Lejeune is a rising star in women's pro cycling, but this Frenchwoman (and now Arizonian) is no stranger to speed. With roots in Tri and a number of impressive running records in her native country, Cécile has been challenging herself since the age of 12. A RED-S survivor, Cécile brings an inspiring and candid story to this year's Life Time Grand Prix, where she currently sits in a top-10 ranking.

AJA #41: Hard water, hard jobs, and hard to get

Marginal Gains Cycling Podcast, Presented by Silca ·

2025/04/30

Fatty is obsessed with mini compressors and so jumps the line in this episode of Ask Josh Anything with several questions he has about Silca's new Elettrico series, Silca's innovative, just-released electric mini pump that is available everywhere (except the US) now. We also got some great feedback/pushback on part of Josh's recent FAQ episode, and a novel new product idea involving tap water from Indianapolis. And, as always, so much more.

Marginal Gains Cycling Podcast, Presented by Silca ·

2025/04/18

We are on the ground at Sea Otter chasing Marginal Gains. A top theme at this year's show is something we have been discussing in our episodes: the wider tire revolution. Older XC tires have found new life on gravel race bikes and tire makers are responding. We hear from two major players on the tire side of things. Plus Dylan Johnson weighs in on how widespread the wider tire movement has become at the pointy end of races. We also wadedinto some new terrirotry: bike rack and bag maker Tailfin talks

We've done plenty of interview episodes before, but this one's a little different. The twist here is we have pro cyclist Melisa Rollins joining as co-host in hopes of improving her chances at Levi Leipheimer's The Growler, a race that boasts the world's largest payout in a one-day race: a $156,000 purse, split evenly among men and women.

But we also wanted to know Josh's thoughts about how the newly-announced tariffs might affect Silca, the businesses it buys from and sells to, and its customers.

Short cranks are all the rage right now, and it just wouldn't be right to let this cycling trend go by without asking Josh to weigh in on its actual merits from aero, weight and engineering perspective. We've also got practical answers for your tire inserts and rolling resistance questions, measuring CRR, old-school cables and bar tape strategies, and an inquiry into the compromises tandem and benefits of tandems.

We could have talked with Sofia Gomez Villafane for hours about nothing but her head-spinning palmares: Olympian, winner of Lifetime Grand Prix Series in 2023 and 2024, Leadville, twice at Unbound and Sea Otter, Belgian Waffle rides, and so much more. But the fact is, her wins are just the exclamation marks to the powerful voice Sofia is bringing to the sport.

We talk about how the Silca Endurance chip might affect your lube schedule, the challenges of riding with a waxed chain in very cold weather, strategies you can use to reduce / remove speed wobbles on your bike, how a racer in the Leadville 100 MTB might make his artificial knee more aero, and much more.

If the premise of these Q&A episodes is that you can Ask Josh Anything, and we continue asking questions forever, shouldn't we really change the name of this series to "Ask Josh Everything?" The answer to that question is, of course, "it depends." In this installment, Josh addresses the surprisingly contentious oval chainring, speculates on why a squeaky wheel is squeaking, talks about the present and future of TPU tube recyling...but not before Fatty line-jumps with his current fascination: how,
