About this episode

The episode discusses the new Shimano R9300 Dura-Ace release, pro bike fit trends, the impact of AI on tech help, and features a segment with Zach Edwards on various bike maintenance topics.

This week we got new Shimano R9300 Dura-Ace, although not quite the release many had wished for. Escape’s senior tech editors, Dave Rome and Ronan Mc Laughlin, talk through this new release, the details that are easily overlooked, and where Shimano could do more. Ronan then shares what he saw while covering tech at the Tour de France and how perceived trends can often be false. Dave then raises the increasing problem of Large Language Models (aka, Ai answers) leading people astray in topics that have limited information available online. There’s also a bit of interesting tech news from Silca and Tune. As per usual, members of Escape Collective also get Ask a Wrench. This week, Zach Edwards of the Boulder Groupetto joins Dave to cover topics such as noisy drivetrains, why aero isn’t more prominent in downhill racing, and what we look for in good headset cable routing.
