Compare three proven starting points: the 109% pedal-to-saddle method, the 96.5% bottom-bracket method, and the LeMond 88.3% formula. Correct saddle height is essential for comfort, injury prevention, and efficient pedaling.
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. For the full picture, see our complete bike fitting guide.
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.

Once your height is right, the saddle shape itself is the next biggest comfort lever.
