Rex 9071 Black Diamond Chain Lube Workshop size, 225 ml

Rex Black Diamond - wax-based, “fastest ever” chain lube.
Black Diamond particles are mixed into the lube in a time-consuming ultrasonication process. The new combination reduces overall friction, decreases wear, and also possesses improved rain resistance.
The new lube is simple to apply. First, de-grease the chain, then just a single drop to each chain roller before you ride. Black Diamond does not use an evaporative solvent carrier, so you can ride immediately after lubing up.
