Unlike every other bike product in the world, the 'Lite' in Dumonde Lite Bicycle chain lube doesn't refer to its weight. Well, not in the usual sense. It refers to viscosity. The reason that this is so important is that you want a clean drivetrain. Heavy (thick) chain lubes leave a wet, sticky residue on your chain. That attracts dirt, which is cycled through your drivetrain. Dumonde Lite quickly works its way into your chains pivots and forms a low-friction plastic plating which bonds to the chain. It's designed to leave your chain feeling dry, so dirt falls off before it gums up your drivetrain. Which is nice, because dirt is one of the reasons that drivetrains die.
