Rex Black Diamond is one of the most researched chain lubes on the market. Wheel Energy Oy’s laboratory tests have confirmed that its friction level is among the lowest in the indu stry. Additionally, Black Diamond has broken records in Australia’s most respected Zero Friction Cycling tests, which measure the impact of chain lubes on chain wear over long, demanding tests simulating both road and off-road conditions. Currently, Black Diamond is one of the longest-lasting chain lubes on the market based on single-application durability tests. Show more
