1. Maintain Proper Posture
For beginners and leisure riders who simply want to relax on a bike, the ideal saddle position is: a shorter top tube; minimal height difference between the saddle and handlebars. Riders with back issues should also choose this posture, as it reduces the strain on back muscles. With regular training, the handlebar height can be lowered. However, it’s important to note: any changes must be adapted to gradually. Even a half-centimeter difference can have a significant impact. For trained riders whose back muscles have adapted to the demands of cycling, a forward-leaning posture can be attempted. A longer top tube forces the upper body to stretch forward, shifting the body’s center of gravity forward and placing more load on the shoulder muscles. A larger height difference between the saddle and handlebars also forces the torso downward, increasing the burden on the back muscles. This posture is not suitable for beginners or those with back problems. For road racing cyclists, however, this posture helps reduce wind resistance.
