Rex winter chain lube -30°C (-22°F). Based on the popular Rex Domestique chain lube, the Rex Arctic is a wax and oil hybrid lube that is resistant to snow, frost and road salt. Its composition has been improved for winter conditions with Rex N-Kinetic hydrophobic polymers. The improved winter properties include even better water resistance and effective corrosion prevention. The viscosity of Rex Arctic is optimized for cold conditions, and it lubricates without congealing even in the hardest frosts. Every drop is 100% lubricant and not something that will evaporate into the air. Unlike with most chain lubes, there is no need to wait until the solvent evaporates before you can ride your bike. You can think of it as a concentrated chain lube. Thats why only a small amount of lubricant is need to keep the chain smooth and silent. Rex Arctic shares the well documented lubricating performance and longevity of Domestique, and is thus among the best in it class. Despite its small size, each
