The secret of the new chain oil is the diamond-hard and durable Black Diamond particles, which are mixed in small quantities with a lubricant in a time-consuming ultrasound process to ensure the best quality. When the drive is in motion, the particles form an extremely durable and diamond-hard surface layer on the metal-metal contact surfaces, which significantly improves the lubricating properties of the chain oil. It extends the life of your drive by reducing friction, improves gear shifting and better lubricity when wet. The Wheel Energy Oy laboratory is one of the few laboratories worldwide that specializes in measuring power transmission losses. This domestic laboratory, used by professional teams and competitors, was also an important partner in the development of the REX Black Diamond. In a test with a dynamometer that simulates a 300-mile race, the REX Black Diamond achieved the best result, leaving behind competing high-end chain oils. The test report was prepared by Wheel Energy without instructions from REX. In addition to the laboratory tests, the Black Diamond has also won many races and won a stage win at the Tour de France in 2019.
