Heel method
This is a very common and simple method. When you sit on the saddle, put your heel on the pedal, adjust the height of the saddle so that your leg is perpendicular to the pedal and see if it is level with the lowest hip bone. However, this method has not been scientifically verified, which often leads to too low saddle. Professor Will Pelever of Mississippi Women's University has published many papers to compare various adjustment methods. She said: "The main problem of this method (heel method) is that it does not take into account everyone's different physiological structures, such as the length difference of thighs, calves and footboards."
Just after adjustment, the body may not be used to it, but this does not mean that it does not adapt. Don't rely too much on comfort. Pelever said, "If the saddle position is far below the optimal position when you step on the pedal, you will feel uncomfortable at first." "However, when your body adapts to the new saddle position (usually within two to three weeks), you will not only feel comfortable, but also get good riding effect for a long time." Of course, if you still feel uncomfortable with the saddle after a few weeks, you will need to readjust it.
