Backward positioning of the saddle has what effect on stress to the knee?

The backward positioning of the saddle tends to decrease the stress on the knee joint during activities like cycling. When the saddle is positioned further back, it allows the rider to maintain a more favorable alignment of the lower extremities, which reduces the angle at the knee and consequently minimizes the load on the knee structures.

A more rearward saddle position often shifts the body weight back more onto the rear of the bike, promoting proper hip extension and allowing for more effective power transfer through the pedal stroke without overloading the knee joint. This adjustment can lead to improved biomechanics, ensuring that the knee is not placed under excessive stress, particularly during high-intensity activities.

While other positions may lead to increased stress or have variable effects depending on individual anatomy and riding style, a backward saddle position is generally recognized for its potential to alleviate knee stress.
