Bike Fitting Methods Explained
Modern fitting combines foundational formulas with rider-specific context. No single method solves everything in isolation, which is why the guide library matters.
Different methods answer different questions inside the full fit workflow.
Comparison
Where each method fits
Use formulas as strong starting points, then validate them against the rider's stability, flexibility, and real riding context.
LeMond / Hamley Saddle Height
Baseline saddle height from inseam
Strength: Simple and repeatable starting point
Limit: Needs personal adjustment for flexibility and goals
KOPS (Knee Over Pedal Spindle)
Saddle fore-aft reference
Strength: Easy workshop reference
Limit: Not a complete performance model
Dynamic / Motion-Capture Fit
Joint angles under pedaling load
Strength: Rich movement data
Limit: Requires equipment and specialist time
