We cover:
- Real aerodynamic data: 3-8 watts saved at race speeds by going narrower
- Why Filippo Ganna (6’4″) uses 38cm bars in time trials
- The biomechanics of the “aero hoods” position and how it changes muscle engagement
- Handling and sprint leverage trade-offs you need to know
- How to actually measure YOUR ideal handlebar width (old school vs. new methods)
- Adaptation timelines and red flags to watch for
The truth? Narrow bars offer legitimate aero gains, but the “right” width depends on your flexibility, discipline, and riding goals. Most riders benefit from going 2-4cm narrower than traditional shoulder-width recommendations, but 36cm isn’t for everyone.
Whether you’re racing crits, doing time trials, or just looking for free watts on your weekend rides, this episode gives you the data and practical advice to make an informed decision.
