AJA #38: Waxing Long, Waxing Cold, and Avoiding Speed Wobbles, and Taping to be Aero

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.

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 about its go-fast approach to bike packing. And finally, we met up with a one-of-a-kind company that has brought Marginal Gains...to leg shaving. 

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. 

We had a whole suite of super nerdy and fun questions ready to ask Josh...and we will still ask them, next time. 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. The resulting unscripted conversation is a must-listen. 

2024 Unbound Champion Rosa Klöser’s trajectory to the top step started with a stolen townie, and has kept surprising —and impressing — ever since. You're going to love this conversation with this analytical, detailed, smart, and fast fellow marginal gainer.   

This is a little different from most Ask-Josh-Anything episodes. Here, we ask Josh to answer the questions he gets most often. What we got was an insightful hour of experiences, career advice, and thoughts on the culture within pro cycling teams. This is seriously an episode you do NOT want to miss.

Jonathan Lee is Communications Director and one of the OG’s at TrainerRoad, one of our favorite tools for marginal-gaining our bodies. TrainerRoad is all business (or at best, Type 2 fun) about making you the strongest, fastest version of yourself...or at least, it was that way until recently. Hottie and Fatty talk with Jonathan about TrainerRoad's why, how, and what's next. 

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. Do not miss this smart, instructive and fun interview with the top off-road woman in North American racing.  

The Marginal Gains crew thought we'd throw a real curveball this episode and make every single question about cycling...and relevant, even. Wacky, huh? 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.
