How to Use This Calculator

How the result changes with Inseam (cm)

Inseam (cm): Barefoot inseam measurement from floor to crotch in cm.
Torso length (cm): Measured from sternum notch to the saddle contact point (sit bones).
Arm length (cm): Shoulder joint to wrist crease in cm.
Shoulder width (cm): Biacromial width (outside edge of each shoulder) in cm.
Flexibility (0-2): 0 = Limited (stiff), 1 = Moderate, 2 = Very flexible.
Riding style (0-2): 0 = Aggressive/race, 1 = Sport, 2 = Endurance/comfort.

Saddle height (cm): Bottom bracket center to saddle top along seat tube (LeMond method: inseam × 0.883).
Saddle setback (cm): Saddle tip distance behind bottom bracket center.
Effective reach (cm): Combined stem + top tube reach from saddle to handlebars.
Saddle-to-bar drop (cm): Height difference between saddle and handlebars. Positive = bars lower than saddle.
Handlebar width (cm): Recommended handlebar width based on shoulder width.
Crank length (mm): Recommended crank arm length (rounded to nearest 2.5 mm).

Identify Input Parameters
4 parameters
Inseam (cm) = 82, Torso length (cm) = 60, Arm length (cm) = 63, Shoulder width (cm) = 42 = 6 input(s) provided
Calculate Saddle height
Saddle height = inseamCm * 0.883
72.4 = 72.4
Calculate Saddle setback
5.4 = 5.4
Calculate Effective reach
Effective reach = (torsoLengthCm + armLengthCm) * 0.47
57.8 = 57.8
