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!

It’s the first week of the Tour and Escape’s geeks are seemingly all down different rabbit holes. This week, Dave Rome is joined by new hire Jack Duncan to talk through the week in cycling tech, which seems to involve a handful of juicy rumours.

From rumours of new Dura-Ace to big wheels from big brands, there’s a lot to chew on. Dave and Jack also discuss airbag tech that keeps circling big budget teams. And there’s some tool talk for the wrench-enthusiasts.

The free episode wraps up with Jack jumping on a call with aero clothing expert Johannes Rom Dahl (of Fusion) to try to get an answer on whether being in Yellow (or another leader jersey) has an aero disadvantage.

It’s the week of the Tour de France Grand Départ, and with it have come a few big bike launches. Escape’s senior tech editors, Dave Rome and Ronan Mc Laughlin, jump on to discuss whether Specialized’s new Tarmac hits the mark.

There’s also a new bike from Orbea. Plus Dave asks Ronan to confirm just how progressive his fit is, and as it turns out, the answer is not very. Ronan then jumps on a call with Daan Teugels from Belgian Cycling Factory to discuss how Eddy Merckx’s reduced-frame-size options can still meet racers' needs.

As always, members of Escape Collective don’t just support independent journalism; they get access to everything we have to offer. For Geek Warning, that means access to the weekly Ask a Wrench segment, where pro mechanics answer our member’s tech questions.

It's time for a Geek Warning crossover episode! Ronan Mc Laughlin and Jack Duncan join Caley Fretz ahead of this year's Tour de France to break down how bikes and gear are changing and highlight what our tech reporters think will be the most important equipment of a modern Tour.

The tech crew at Escape Collective have been paying close attention to the progression toward 32in wheels in gravel and mountain bike, and while the conversation has come up a few times, it felt time to dedicate some real time to the topic.

This week, Escape tech staffers Dave Rome, Ronan Mc Laughlin, and Alex Hunt chat about 32ers in the news, whether the UCI’s potential involvement will slow things, and if a new wheel size is of positive net gain for the wider industry.

In addition to big wheels, the geeks also talk about some other new products. Meanwhile, members of Escape Collective get Ask a Wrench, the weekly segment where our members’ technical questions get answered.

This week, Dave, Ronan, and new guy Jack chat about Eddy Merckx’s new bike and why it’s surprised Ronan. The bike provides good fodder for diving into more serviceable cockpits and for understanding why only fashion may limit the uptake of progressive road geometry.

There’s good news for those who prefer cable-actuated shifting, as Shimano has updated its mountain bike offerings. Dave has other things on his mind, too, including Australia’s Spoken bike show and how downhill is teasing future puzzling for disc brakes.

Of course, there’s plenty more than that, and members of Escape Collective also get Ask a Wrench at the end of the episode (members-only feed).
