We say it all the time. Chain Wax is THE SOLUTION to the bicycle drivetrain problem. Not only because it's more efficient, yes that's a huge benefit. But with that comes cleanliness and increased longevity of drivetrain components. With cost to run calculators (such as @zerofrictioncycling's,) that factor in component wear all chain waxes are about 1/4-1/5th the cost to run compared to THE BEST oil based lube (our own #SILCA Synergetic).
