What can be inferred if there is visible wear on a chain?

Visible wear on a chain often indicates that the chain is undergoing stress due to misalignment. When a chain is misaligned, it experiences uneven contact with sprockets and other components, leading to accelerated wear. This wear can manifest as elongation, pitting, or surface degradation, which not only diminishes the chain's efficiency but also increases the risk of failure.

When chains are operating properly, they should exhibit uniform wear patterns and maintain their integrity over time. If wear is pronounced, it serves as a signal that the alignment of the drivetrain must be evaluated and corrected to prevent further damage and ensure optimal performance. Addressing potential misalignment early can prolong the life of the chain and improve overall system efficiency.
