Creaking and squeaking noises can be annoying, and can also be a sign of more serious problems. Damage or excess wear to components may result if they are left unattended. Creaking is usually caused by two things rubbing together, such as a crankarm rubbing on a spindle. Many of the solutions below rely on adequate torque on the parts — see also this article on Bicycle Torque Specifications. Thread preparation is also critical — see also Basic Fastener Concepts. The best method of identifying a noisy component is by going on short test rides and paying close attention to when and where the noise occurs. If during a ride you hear a creak or squeak once per revolution, it is probably located in the crankset and pedal area.
