About this episode

Josh discusses race number pinning, TPU tube technology, indoor training setups, and the UCI-SRAM cog controversy.

Josh tackles why we're still pinning race numbers instead of printing them on jerseys, then dives into the tech story behind Silca's translucent TPU tubes. We talk about real-world marginal gains for everyday riders, and Fatty's recommendations for indoor training setups. Last but not least, you do NOT want to miss Josh's unfiltered take on the UCI–SRAM 10-tooth cog controversy.
