Whats the most effective way to apply wax to a chain with a complex shape, considering the numerous nooks and crannies that can trap dirt and grime? Ive seen some chain wax applicators on the market, but they seem to cater to modern, sleek chain designs, leaving those of us with older or uniquely-shaped chains out in the cold. Should we be using a specific type of wax or a particular application method to ensure maximum protection and minimal mess? And whats the deal with these chain waxing tutorials that never seem to address the issue of complex chain geometries - are they just assuming everyones riding a carbon fibre road bike with a pristine, factory-fresh drivetrain?
