Introduction
Bike fit is the most important factor for performance and comfort. A poor fit creates pain, reduces power, and increases the risk of injury. A good fit means free watts and pain-free miles.
The 5 Contact Points
Your body is in contact with the bike at 5 points: both hands, both feet, and the perineum. Each of these points must be optimized.
Fundamental Adjustments
Saddle Height
The most important adjustment. A saddle that is too high or too low degrades everything else. LeMond Method: inseam x 0.883.
Saddle Setback
Influences weight distribution and knee angle. Generally, the knee should be vertically aligned with the pedal axle at the 3 o'clock position.
Handlebar Height
Determines torso angle and hand load. The lower the handlebars, the more aerodynamic the position, but the less comfortable it is.
Stem Length
Influences the distance between the saddle and the handlebars. A stem that is too long creates back and shoulder pain.
Cleat Adjustment
Clipless pedal cleats should be aligned with the natural axis of the foot to avoid knee pain.
When to get a professional bike fit?
If you ride more than 5 hours a week, if you have chronic pain, or if you want to optimize your performance, a professional bike fit is essential. Expect to pay €150-300 for a complete session.
Conclusion
A good bike fit changes everything. Like a good David & Clément wall mount, it's an investment that pays off on every ride.
