Ranking Marginal Gains With Josh Poertner | GCN Tech Show Ep. 388

Want to unlock speed? We're joined by the ultimate authority on cycling performance, Josh Poertner from SILCA, to rank the marginal gains that actually make a difference – and those that might be overhyped! 👀

From Ceramic Bearings and Titanium Hardware to Aero Helmets, Aero Socks, Nasal Dilators, and even the benefits of Wind Tunnel Sessions and Oversized Pulley Wheels, Josh gives his expert take. We also dive into Waxed Chains, Performance Tyres & Tyre Pressure, and the surprising impact of a Clean Bike! What did we forget to ask him about?

PLUS, stick around for our "Hot Tech" segment featuring the stunning new Pinarello Edizione Speciale Giro 50, Silca's Synergetic Race Grease, the Standert Kreissäge RS, the Kask x Cinelli Utopia Helmet, and Enve's Hex Carapace Gravel Tyres.

And of course, we've got your Gubbins Of The Week, Comments Of The Week, and the ever-popular Bike Vault!
