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.

We’re going back to basics in this week’s episode. While Geek Warning is usually for tech-obsessed cyclists, this edition covers the common conversations a bicycle mechanic would have with a client. It’s for everyone and anyone who does a little of their own bike maintenance.

Many road cyclists are still relatively new to disc brakes, so Jack Duncan and Dave Rome start the episode with a deep dive into many facets of ownership. The basics of chain lube and drivetrain wear are covered later on, as are some thoughts about tyre wear and who tubeless may be right for.

After all that, members of Escape Collective get the usual Ask a Wrench segment, this time with the return of a familiar voice.

Dave and Jack are back for another round of Geek Warning. This week, new road bikes from Cervelo and Pinarello bring the discussion to topics such as what makes a good endurance road bike, where emerging Chinese brands are seeing success, and why aero bottles are an impractical feature.

In this episode, you’ll also hear what Dave considers the best multi-tool and plenty more.

Meanwhile, listeners on our members-only podcast feed will hear "Ask a Wrench" at the end of the episode. This week, Dave Rome is joined by pro mechanic Colin Williams to answer questions about sticking Shimano dropbar levers, how to handle failed internal dropper-post routing, and a difference in SRAM chains that the company has remained silent about.

Happy geeking!
