The bicycle crank link is an important component of the bicycle transmission system, mainly responsible for transmitting the rider's pedaling force to the wheels, thereby achieving the movement of the bicycle. The crank chain link system includes a crank and a toothed disc, which are connected together through a central axis to form a complete transmission mechanism.

The crank is the part of a bicycle that is connected to the toothed disc, and its main function is to transmit the pedaling force to the toothed disc. The fixing of the crankshaft is usually achieved through bolts, and if the crankshaft becomes loose, it may make a clicking sound. When checking if the crankshaft is loose, you can turn the crankshaft to a horizontal position, press down firmly on both sides of the crankshaft and rotate it 180 degrees. If the crankshaft shakes, you need to tighten the fixing bolts
