The design principle of bicycle seat clamp is relatively simple. When the seat tube is inserted into the seat tube clamp, the spring arm of the seat tube clamp will contract and generate elastic force, which firmly fixes the seat tube on the seat tube clamp, thereby ensuring the stable position of the seat tube. Seat tube clamps made of different materials, such as aluminum alloy, stainless steel, or carbon fiber, can ensure quality while reducing the overall weight of the bicycle. Some advanced seat tube clamps also have adjustable spring force and angle functions to meet the needs and usage scenarios of different users
