AJA #37: Oval Chainrings, Squeaky Wheels, and Everesting Hypotheticals

Dec 09 2024 52 mins

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

Marginal Gains Scorecard with Dylan Johnson

Nov 23 2024 65 mins

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

AJA #36: Pre-wax prep, traction problems, and aero for the flexibility-challenged

Nov 12 2024 52 mins

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 ho

Zwift & Marginal Gains, with Zwift Product VP Mark Cote

Oct 28 2024 58 mins

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

Paralympic Track Racer Bryan Larsen: Excelling after Injury

Sep 24 2024 59 mins

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.

AJA 35: Hookless rims & PSI limits, tire pressure on worn tires, Ti quicklinks, CRR on wet roads

Aug 05 2024 51 mins

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

Amy Charity and SBT GRVL

Jul 05 2024 48 mins

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

AJA 34: Wind tunnels, cargo bibs, ti printing, and axle handles

Jun 03 2024 56 mins

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 calcu

Erwin Vervecken and the UCI Global Gravel Series

May 21 2024 56 mins

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
