Saddle height is a starting point, not a final answer. Ride the recommended height for a week before making further changes. These formulas assume typical leg proportions. Riders with unusually long femurs relative to total inseam may need to sit lower than the formula suggests. Persistent joint pain during or after riding warrants a professional bike fit.
