The Story
Independent tests conducted by Zero Friction Cycling (Australia) and Wheel Energy (Finland) have proven Rex Black Diamond to be the longest-lasting and lowest-friction chain lube ever. Even when tested with an extremely long lubrication interval of 1,000 km, Black Diamond outperformed competing lubricants. No other lubricant has shown the same treatment longevity as Rex Black Diamond.
