Wider tyres are faster on the cobbles, right? After all, the pros use them at the Cobbled Classics. Simon discusses why wider tyres are faster on rough roads and why the results of the GCN wider tyre tests weren't quite as we expected.

Pro cyclists previously raced on narrow tyres – sometimes even as narrow as 19mm! But, now it's rare to see them use anything narrower than 25mm, and, for select races, they'll choose 28mm or even 30mm. Wider tyres are particularly prevalent at the legendary cobbled classics; races like Paris-Roubaix and the Tour of Flanders.

Are wider tyres actually faster or is it just a trend? We put it to the test of the brutal cobbled roads of Northern France and Belgium, and, we take an ever deeper dive into the science, tech and geekery of bicycle tyres in this video.
