Saddle Setback Calculator — Fore-Aft Position
Determine saddle fore-aft position from seat tube angle and saddle height.
How We Calculate This
Setback Calculation
Setback = Saddle Height / tan(Seat Tube Angle)
This calculates the horizontal distance behind the bottom bracket based on the geometry. A steeper seat tube angle results in less setback.
