The C in the bicycle stands for cassette, chain, and cranks. The cassette is a set of sprockets on the back wheel that should be checked for wear. If the chain skips or shifts improperly, it may be a sign of excessive wear. The chain itself should be inspected for wear and lubricated regularly. Chains can stretch and should be maintained or replaced as needed. The crank includes the pedals, crank arms, and bottom bracket. Check the pedals for smooth spinning and make sure the crank arms don't have any side-to-side movement. If they do, the bottom bracket may need servicing by a professional mechanic.
