Adam Kerin - Zero Friction Cycling

This interview with Adam Kerin serves as the perfect follow up to our previous episode on chains and lubrication. Adam's Zero Friction cycling is hyper-focused on this key piece of drive train and the ways to make it more efficient and last longer. ZFC is the sole, independent voice of chain and lube testing and a marginal gainer at heart. Josh and Adam go deep on how proper chain care can repay the rider in so many ways.

    Josh,

    As tires and wheels work to standardize widths, why don’t tire manufacturers publish the arc length of the tire cross section from one bead radius tangency to another, when the tire is inflated to the median recommended pressure? Or simpler, just arc length unloaded.

    Sorry couldn’t help myself.

    Question for Josh, in the context of the episode a while back on placebos:

    Would you rather ride a hot melt wax chain that you’d been told was a bad lube, or a bad-lube chain that you’d been told was hot melt wax?
