If you're a fan of the show, please support us!

  • 1:30 meet AeroLab Founder and Associate Professor of Engineering at the University of Calgary, Chris Morton
  • 5:30 what does the AeroLab sensor do?
  • 7:30 how aerodynamic sensors are like toddlers
  • 9:00 the delicate process of setting up an aerodynamic sensor vs something less sensitive to poor data inputs like a power meter or a heart rate sensor
  • 13:00 how much of an expert in aerodynamics do you need to be to make use of an aero sensor?
  • 15:30 currently there is a substantial gap in the knowledge of what to do with aero data
  • 22:00 Chris’s preliminary research into the interplay between biomechanics and aerodynamics in bicycle fitting
  • 24:00 the value of measuring wind direction as well as magnitude with the multi-hole pitot tube in the AeroLab sensor
  • 25:15 demonstrated sail effect from disk wheels!
  • 26:30 wind average drag: drag performance across all yaw angles encountered that day
  • 30:00 the data collected by the AeroLab sensor and how it is used
  • 35:15 for an experienced rider, CdA data convergence can happen in as little time as 10s!
  • 37:00 1 equation and 2 unknowns! How to solve for both aerodynamic drag (CdA) and rolling resistance (CRR). 
  • 41:45 the inputs needed for the algorithm
  • 46:30 AeroLab vs competition on CRR
  • 53:00 baking in both CdA and CRR in testing for the most efficient setup
  • 54:45 about CRR breakpoints and the data AeroLab is collecting to predict optimal tire pressure for EVERY race course!
  • 56:30 a case study of optimizing aerodynamics at the Slovenian national TT championships
  • 59:30 getting close to releasing the final product
  • 60:30 first round of commercial product is for coaches, teams, fitters, engineers only
  • 62:30 aero fitters will be able to test up to 6 positions in an hour of testing
  • 63:00 combining wind tunnel testing with CFD and field testing
  • 66:30 the value of improving body position
  • 70:30 aero sensors are for testing and not really for race-day use
  • 72:15 using the aero sensor to analyze draft effects in legal draft packs in triathlon
  • 75:00 getting an AeroLab assessment done in your area
