Calculate your optimal saddle height using three proven methods — the 109%, Hamley, and LeMond formulas. Correct saddle height is essential for comfort, injury prevention, and maximum pedaling efficiency.
Saddle height is the single most important adjustment on your bike. It directly affects your pedaling efficiency, comfort, and injury risk. A saddle that is even 5-10mm too high or too low can cause knee pain, reduce power output, and make long rides uncomfortable.
The correct saddle height ensures optimal leg extension at the bottom of the pedal stroke — typically 25-35° of knee flexion. This allows your major muscle groups (quadriceps, hamstrings, and glutes) to work through their most efficient range of motion while minimizing stress on joints and tendons.
The simplest formula: multiply your inseam by 1.09.
