Sam Barley, a bike fitter, aero tester for Body Rocket and triathlon coach is on the show to discuss aerodynamic testing and how it shapes bike fit. He shares how he moved from traditional bike fitting to aero-guided fit. Sam reveals surprising findings from testing top athletes, showing that what looks fast isn't always best and that real-world aero gains can differ from expectations. The conversation also covers how athletes balance getting more aero with staying comfortable and powerful for races on varied terrain. Key Takeaways * Aero Testing is Key: Sam uses tools like Body Rocket for precise aerodynamic measurement. * Surprising Results: Testing shows that sometimes higher positions are faster, and typical aero gear might offer smaller gains than expected. * Comfort vs. Speed: It's vital to find an aero position that a rider can maintain comfortably and powerfully throughout a race. * Race-Specific Setup: Elite athletes adjust their aero positions based on specific race courses and demands, not just one "fastest" setup. * Practical Advice: For better aerodynamics, focus on your bike's adjustability and integrate hydration/nutrition into your aero setup during training.
