Why do all the self-proclaimed gear experts on here claim that using a chain lube with water repellent properties is essential, when in reality its just a bunch of marketing hype meant to fleece roadies out of their hard-earned cash? Its not like were all racing in the Tour de France, or that the roads in our local crit series are suddenly going to turn into the Tour of Flanders. Exactly what benefits are we really talking about here - a few grams of weight savings, a slightly quieter chain, or some other mythical advantage that only applies to the 1% of cyclists who actually ride more than 500 miles a month? What are the actual, proven benefits of using a chain lube with water repellent properties, and can someone please provide some real-world examples of how this supposedly miracle lube has improved their ride?
