The renewed, second-generation Black Diamond chain oil takes advantage of innovations in hot wax: a higher wax content has been achieved by melting in the maximum amount of Rex hot wax. The new version combines the separate e-bike version into a single product. The new combined oil is the best in its class with revolutionary wear resistance. Save money because your chains will last longer!
Rex Black DIamond is one of the most researched chain oils on the market. Its friction level has been found to be one of the lowest on the market when measured by Wheel Energy Ltd's laboratory. In addition, Black Diamond has also broken records in tests conducted by Australia's most prestigious industry body, Zero Friction Cycling, which measures the effect of chain oil on chain wear in long and demanding tests simulating on-road and off-road riding. Black Diamond is currently the longest lasting chain oil on the market when measured against the duration of a single lubrication.
Most of the chain oils available contain volatile solvents or even water. This is a good way to reduce manufacturing costs, but at Rex we thought otherwise. Every drop of Rex is 100% lubricant; everything you put in your chain stays there and doesn't evaporate into the air. This means you can get around thirty lubrication cycles from a small, easy-to-carry bottle. Apply a drop per joint and you're ready to ride.
