This guide redefines cycling performance by placing aerodynamics at the core of training.
A scientific approach to measure and optimize the real impact of your position on speed.
What readers say about our guide
Can save up to 45 minutes on an Ironman, increase sprint speed by up to 6 km/h, or save more than 50 W at constant speed.
Without changing equipment.
A clear and concise 60-page guide
Physical principles explained simply to understand aerodynamics
Analysis of 4 real performances based on true aerodynamic mastery
A method to estimate your real gains in speed, time and watts
A practical framework to train your aerodynamic position effectively
Athletes, coaches and bike fitters who know position has a decisive impact on performance.
If you believe performance only comes from producing more watts or changing equipment.
Aerodynamics would only matter above 35 km/h or be only about equipment. Physics shows otherwise.
Improving performance means optimizing speed, not just power.
Evaluating aerodynamic efficiency is the foundation for riding faster without more effort.
An optimal position can reduce aerodynamic drag by up to 30%.
Understand why your sensations make you lose precious minutes
Assess how much time you can gain with an optimized position
Discover the 3 pillars of true aerodynamic skill
Structure your training to master your aerodynamics
Experience a new feeling of speed and fluidity you’ve never known before

A scientific, practical and immediately applicable approach to understand and train your aerodynamics.
