BulletPoint3 : Shock absorption and noise reduction: The connection points of the surfing accessories are equipped with built-in elastic gaskets, which effectively absorb the vibrations generated during paddling, reduce the friction noise between the paddleboard fins and the board body, and provide a quieter and more comfortable paddling experience. BulletPoint4 : Stable connection: The top fin replacement part can tightly connect the paddleboard fin to the paddleboard, ensuring that the fin does not easily loosen or fall off during rowing.
