That Triathlon Show Tire pressure, aerodynamics, and smart equipment upgrades with Josh Poertner | EP#235
Josh Poertner has spent most of his life in the cycling industry. First racing professionally in Europe, then working with Zipp as technical director before becoming the CEO of Silca. He also consults with professional cycling teams. Josh knows all the ins and outs of tire pressure optimisation, a topic we discuss in-depth in this interview. We also discuss a variety of other equipment upgrades that can make you faster on the bike, and importantly, the hierarchy of getting the most watts for your buck when it comes to such purchases.
IN THIS EPISODE YOU'LL LEARN ABOUT:
-Optimising tire pressure (and the potential cost of getting it wrong)
-Equipment choices and watts-for-buck: bike frame, wheels, and nutrition and hydration setup
-Equipment choices and watts-for-buck: helmet, clothing, socks, shoes and shoe covers
-Equipment choices and watts-for-buck: drivetrain friction, ceramic bearings, oversized pulleys, 1x drivetrain
