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.

And apologies for the audio this week, as Dave accidentally landed on his backup microphone.
