Why Saddle Height Matters
It affects knee health, pedaling efficiency, and comfort.
Five Calculation Methods
Method 1: Monoique Formula
Inseam × 0.885 = Saddle height
Example: 85 cm × 0.885 = 75.2 cm
Method 2: Knee Flexion Angle Method
At the bottom of the pedal stroke, the knee should be bent 25-35 degrees.
Method 3: Heel Test Method
Place your heel on the pedal; the knee should be slightly bent (15-25 degrees).
Method 4: LeMond Equation
Inseam × 0.893, slightly higher than the Monoique formula.
Method 5: Dynamic Analysis Method
Use professional equipment such as Retül or BikeFit for precise measurement.
Common Symptoms and Adjustments
| Symptom | Cause | Solution |
|---|---|---|
| Pain in front of knee | Saddle too low | Raise the saddle |
| Pain behind knee | Saddle too high | Lower the saddle |
| Hip discomfort | Saddle too high | Lower the saddle |
Do not adjust more than 5 mm at a time.
Conclusion
Combine formulas, comfort, and dynamic analysis, and make regular fine adjustments to find the optimal height.
