A few weeks ago, we headed to the wind tunnel at the Silverstone Sports Engineering Hub to find out what the best-value aero upgrades are.

Our aero guru for the day was Stephen Roche, The Bike Tailor – an expert in bike fitting, aero testing and custom builds, based in London and Brighton.

Off the back of that test, we sat down for a chat with Stephen, with the aim of demystifying wind tunnel testing.

As well as discussing how we set up our own test, Stephen explains why cycling brands love to do wind tunnel tests at such high speeds, how wind tunnel results translate into the real world, and much more.
