1x VS 2x, OSPW Advantages and Optimal Chain Line | GCN TECH CLINIC SPECIAL

Join us in the GCN Tech Clinic as we sit down with Paul, Head of Product Education at CeramicSpeed, for a deep dive into drivetrain efficiency, bearings, and marginal gains. We cover everything from the efficiency of oversized pulley wheels (OSPW) and 1x vs 2x systems to chain maintenance, lubricant choice, and how power output affects friction. If you're looking for free speed and answers to your biggest tech questions about your bike's drivetrain, you won't want to miss this!

The CeramicSpeed team says a 2x drivetrain is more mechanically efficient than a 1x system due to better chainline and larger chainrings! Are you team 1x or 2x, and why? Let us know in the comments! 👇
