About this episode

The episode discusses cycling tech rumours, airbag technology, and the aero cost of wearing a leader's jersey during the Tour de France.

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.
