The Domestique Chain Lube is a great success. In tests in two independent laboratories, it came straight to the top. It significantly minimizes chain friction and is economical due to long maintenance intervals. Rex does not add additional solvents or water and thus avoids the evaporation of liquid. Everything you put on the chain stays there and reliably lubricates the drive train. Before the first application, the chain should be degreased thoroughly. The optimal lubrication performance is achieved after 3-4 applications when the chain oil has completely penetrated the individual links.
