Summer Merino Secrets: Pinebury Gear, Drop Bar MTB Taxonomy, and The USA Trail | Ep. 73

In this episode of ShiftLess, the crew braves the 100°+ Texas heat to talk about why you should probably be wearing wool in the summer. We are joined by Kyle Rancourt, founder of Pinebury, to discuss the science of "New Yarn" technology and the future of made-in-the-USA cycling apparel.Whether you are prepping for The USA Trail, refining your Basepacking rig, or just trying to survive a local gravel grinder, this episode breaks down the gear and mindset needed for ultra-endurance unpaved cycling.Midnight Mash Recap: Brad shares his strategy for a sub-4-hour finish, the "Tailwind-only" nutrition plan, and a sobering reminder of why event promoters probably shouldn't ride their own races.The Taxonomy of "Drop Bar Mountain Bikes": We dive into the Radavist vs. Bikepacking.com debate. What actually defines this category? We look at the 2.2" tire minimum, boost spacing, and the "timeless" geometry of bikes like the Salsa Fargo and Cutthroat.Olympic Tactics: A breakdown of Kristen Faulkner’s gold-medal road race win. Why smaller teams and a lack of radios made for the best "chess match" on wheels in years.Guest Interview: Kyle Rancourt (Pinebury):The "Summer Wool" Revolution: How a 17-micron fiber and patented "New Yarn" technology creates a shirt that is 9x stronger and 5x faster-drying than traditional merino.From Shoes to Jerseys: Kyle discusses his heritage in the Maine shoemaking industry (Rancourt & Co.) and why he transitioned to high-performance cycling apparel.The Secret Sauce: Why wrapping merino fibers around a nylon filament (rather than twisting them like a rope) preserves elasticity and durability.To understand why Pinebury's gear works for ultra-endurance cycling in the heat, you have to look at the yarn structure. Unlike traditional wool that is twisted into a rope, "New Yarn" uses a performance filament core.This structure allows for better aeration and moisture management, which is critical when you are out on the trail for days at a time. This level of durability is what the ShiftLess crew looks for when scouting sections of The USA Trail or setting up a Basepacking camp.Kyle was generous enough to offer a heavy discount for the "ShiftLess 13."Site: Pinebury.usCode: SHIFTLESSOffer: 20% OFF your order (Valid through the end of 2025).Episode HighlightsUnderstanding the Tech: New Yarn vs. Traditional MerinoExclusive Coupon Code for ShiftLess ListenersReach out and touch us: [email protected]
