What are the best practices for applying bicycle chain lube to ensure optimal performance and longevity of the bicycle chain?

To ensure optimal performance and longevity of a bicycle chain, it is best to apply a small amount of chain lube to each link, wiping off any excess to prevent buildup. It is important to clean the chain regularly and reapply lube after riding in wet conditions. Additionally, avoid using too much lube as it can attract dirt and grime, leading to faster wear and tear on the chain.
