How often should I clean my road bike chain to ensure optimal performance and minimize wear, considering the chains material, riding conditions, and the type of lubricant used. Is the conventional wisdom of cleaning the chain after every ride or 100-200 miles still applicable, or have advancements in chain technology and lubricants changed the game. What are the metrics that dictate when a chain needs cleaning, and how do I balance the need for cleanliness with the potential for over-cleaning, which can strip the chain of its lubricant. Are there any best practices or guidelines for determining the ideal chain cleaning frequency based on specific riding conditions, such as commuting in a dirty urban environment versus riding on clean, smooth roads.
