From Birmingham, UK we welcome back Xavier Disley. He is the lead analyst for Aero-Coach in the UK which specializes in finding an optimal mix of aerodynamics and power production outside of a wind tunnel in velodromes. He is also a coach for RST Sport LTD and lectures on biomechanics to sports science students. Xavier’s podcast analyzing the hour attempts was very well received and I have been thinking of ways to concentrate his knowledge to topics that would be informative yet not overwhelming in content. I thought it might be helpful to concentrate on some basic information to use as a foundation for a good, sustainable aero position.
