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.
