What are the benefits of using a chain lube with low maintenance properties, particularly in terms of its impact on drivetrain efficiency and wear rates, and how do these benefits compare to traditional chain lubes that require more frequent application and cleaning. Does the reduced maintenance requirement of these low-maintenance chain lubes compromise their ability to provide adequate corrosion protection and wear reduction, or are there other factors at play that mitigate these concerns. Can users expect to see significant improvements in terms of chain life and overall drivetrain performance, or are the benefits more nuanced and dependent on specific riding conditions and bike setup.
