Have We All Got Tyre Width WRONG | GCN Tech Show Ep. 454

Pro cyclists are increasingly moving away from 28mm tyres in favour of 30mm, but is the data actually on their side? This week, we dive into the marginal gains of tyre width, rolling resistance, and how modern rim standards (ETRTO) are changing what "30mm" really means. Plus, we look at the new Ridley Kanzo Fast 2.0 aero gravel bike, Columbus’s surprising move into the wheel market, and some stunning custom builds in the Bike Vault!

WorldTour pros are now regularly opting for 30mm tyres over 28mm, even when the data shows a tiny aero penalty. Where do you draw the line between pure speed and comfort for your own riding? Have you made the jump to 30mm+ yet, or are you staying narrow? Let us know in the comments! 👇
