It’s time for another bonus edition of Geek Warning. This chat is a brief opener to our upcoming coverage of Made, North America’s Custom Bicycle Show.

Held this coming weekend (21-23rd of August), the Portland-based show has grown to be a key event on the calendar for bike lovers, tech nerds, makers, and the like. A show like this also consistently serves as a crystal ball into emerging segments and tech trends.

One such trend is the emergence of custom frame builders offering pre-built options. In the USA, a number of local frame builders have reduced purchase barriers by offering set models and stock geometry options. The likes of No.22, Moots, and Stinner are all examples of this. Meanwhile, one of the most prestigious names in the titanium space has now joined the list - Mosaic.

For this chat, Dave Rome is joined by Mosaic’s founder Aaron Barcheck, along with chief vibe officer (and founder) of Made, Billy Sinkford.

A heads up that the timing of publishing this episode coincides with Mosaic’s announcement of a 32er gravel bike and its accompanying launch of its own carbon component brand – Zero. The news of this only broke after we recorded this episode and so these products aren’t discussed within. We may do a dedicated chat covering those interesting products in the future.

This week on Geek Warning, Dave is joined by Escape’s Suvi Loponen and Alex Hunt to talk about the latest in cycling tech.

Alex was on the ground at the Tour de France Femmes and came away pondering why 1x hadn’t hit the women’s field like it has the men.

Meanwhile, Suvi has spent the past couple of months riding the new Trek Domane endurance road bike. Dave and Suvi discuss why this bike is likely to be a big win for Trek.

Then, as usual, those on our member-only podcast feeds get access to Ask a Wrench. This week Dave is joined by Colin Williams to answer questions related to replicating fit dimensions between bikes, headset changes, and why high-engagement hubs aren’t more popular in road racing.

Meanwhile, the geeks discuss why rounded bolts are most often user error and how to avoid them (also check out Dave’s Threaded #15 article on the topic).

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.
