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.\nWe 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.","thumbnail_url":"https://img.transistorcdn.com/SCw60put5iXQ9rY7SnULRutKoei_7l2klvq53FqlDBw/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS8xYmUy/NjcyYWI1YjY2OTM5/ZmEzNDAwNmUwNDA1/ZGI2OC5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
