Considering the high-stress, high-wear nature of freeride and downhill bikes, is it reasonable to assume that the best chain lube for these applications would not only provide exceptional lubricity, but also offer robust anti-wear and friction-reducing properties? Or are we simply throwing money at the problem by using high-end, boutique chain lubes that promise the world but deliver little more than marketing hype? Specifically, what role do additives like PTFE, molybdenum disulfide, and boron nitride play in these lubes, and are they truly effective in reducing wear and friction in the high-stress environment of a freeride or downhill drivetrain? Should we be looking at lubes that use alternative base oils, such as those derived from plant-based sources or synthetic hydrocarbons, which may offer improved performance and durability in these demanding applications? Or are we better off sticking with tried-and-true petroleum-based lubes that have been proven to work, even if theyre not the most glamorous or high-tech option?
