Inside Red Bull's laser-powered aero testing with Dan Bigham and the CyclingSpy

For years, cyclists have said, “you can’t see aero.” Now Dan Bigham can.

In this episode, we go inside Red Bull–Bora–Hansgrohe’s groundbreaking use of Particle Image Velocimetry (PIV), a laser-based imaging technique that effectively makes airflow around a rider visible in 3D. Dan joins Ronan and the CyclingSpy to explain how the team used helium bubbles, high-speed cameras, and class-IV lasers inside Catesby Tunnel, an old railway tunnel, to capture the first-ever full-field airflow data behind a cyclist.

We unpack what PIV actually is, how it bridges CFD and real-world testing, and what it could mean for the future of aerodynamic development in cycling. From vorticity maps to quantum computing, this one’s a deep dive into the tools shaping the next generation of aero performance.
