AJA#53: Pantani vs Pogačar, Hairy Arms, Navier-Stokes

Ask Josh Anything is back and a listener wants to know how much faster Tadej Pogacar's bike setup compared to Marco Pantani's. Tadej took down Pantani's KOM on Alpe d'Huez this summer; a record that stood for more than 30 years. Most of it was Tadej's legs but the bike must have played some role. The question is how much? 

Hottie asks Josh about the Navier-Stokes equations. Simply put the equations are the math behind the flow of fluids like air. Open AI recently declared that it had discovered a problem with the math. Josh explains what it could mean for those  who rely on the equations for CFD simulations. 

Speaking  of Aero .. a listener wants to know if his hairy arms would be better off covered with a long sleeve jersey. Naturally Josh's answer is prefaced by "it depends." 

Josh is also asked about the carbon's double personality. In some cases (bats and hockey sticks) it is extremely resilient to impact. But in the case of bike frames it seems to take on a fragile identity.  

FACTOR Bikes - Rob Gitelis

Josh has often spoke of the people in cycling he most admires. Rob Gitelis is a name he mentions frequently. Rob is the head of Factor Bikes. Rob's company is coming up on its tenth anniversary. The rise to prominence has been quick. Barely a year after Rob took over Factor, its bikes were on the start line at the Tour De France. Factor bikes have been ridden to three stage victories at the Tour. Factor has also celebrated wins at the Tour Down Under and a Gold Medal on the Track at the 2024 Olympics. 

Rob's credo is similar to Josh's: performance and quality first. If it costs a few bucks more to make the best, Rob -- like Josh -- can live with that. Nowhere in the Factor lineup is that more evident than the Factor One. The bike has been labeled the fastest in the world. A super aero machine that now has a partner in Factor's Gravel lineup: The Elara. These two bikes represent Rob's pursuit of high performance. The bike world has taken notice. 

Gary Fisher

We believe in staying in touch with the history of bicycles. Knowing where we've been can often tell us where we are going. That idea has been frequently used when discussing the emergence of the 32-inch wheel. "It's like when we went from 26er to 29er," they say.

But what was it really like to be in the trenches through the birth of the Mountain Bike? The struggle to find parts. The original wheel size dilemma. The passion to push the industry in a new direction. Gary Fisher knows what it was like. Gary -- as you probably know -- is a Mountain Bike OG:  Pioneer. Thinker. Doer. He helped bring a new style of riding and the new bikes to ride on into the world of cycling. He is a part of bicycle history.  

Josh and Hottie talk to Gary about what it took to see a vision become reality. From hanging out with the Grateful Dead to bombing down Marin County's Repack Trail. Gary has a million stories that somehow are stored in one amazing cycling mind. 

AJA #52: Protocol Tire Tech-Cargo Bibs-Long Sleeves for Aero

Hottie and Fatty pepper Josh with tire questions. Specifically what is and is not a radial casing and how his team was able to move towards a radial ply angle without disrupting tire stability. Josh also explains how they arrived at PROTOCOL'S knob shapes and patterns. 

From our listeners we have quesions on putting gels in cargo bibs. Does this result in unnecessary heavy lifting? Josh answers one on the optimal place to mount a mini pump. On the down tube or the seat tube? We also get into why in the spirit of manipulating air flow we don't see more pros wearing long sleeve jerseys?

BWR California 2025 Race Report: Alexey Vermeulen

Alexey Vermeulen’s BWR California Recap: Lessons, Legs & Legacy

April was packed with travel, goals, and hard-fought efforts—but for Alexey Vermeulen, BWR California remained the centerpiece. After flying high at Levi’s Gran Fondo, the legs didn’t quite have the same fire in San Diego. Despite less-than-ideal prep and a solo chase for 3rd, Alexey found grit, rhythm, and perspective on the brutal out-and-back course.

“You HAVE to save something for the return trip.”

From tire choice to travel chaos, dive into Alexey’s full BWR CA report to see how he managed 3rd place on the ENVE FRAY and what makes this course so special to him—even when the win is out of reach.
