Zero Friction Cycling is the world's leading testing laboratory for chain lubrication and is trusted by all major chain lubricant manufacturers. With over 300,000 kilometers of testing under its belt, it has a complete database of the best lubricants on the market. To date, no other lubricant has come close to matching the longevity of Rex Black Diamond, which in tests performed better than competing lubricants even at a surprisingly long lubrication interval of 1,000 km.
- Intended range of use: Lubrication and preservation of e-bike chains
- Weather conditions: all weather conditions
- Type of oil: synthetic with PTFE
- Capacity: 30 g (sufficient for approximately 30 applications)
Rex has improved the Black Diamond formula for electric bicycles in two ways: Nanotungsten (WS2) improves the pressure resistance of the lubricant and further reduces friction. In combination with Black Diamond's proprietary nanoparticle technology, a synergistic effect is achieved. Using both additives in their optimal concentration leads to a result that is better than the sum of its parts. To achieve the best performance, both nano-additives are mixed into the lubricant using an ultrasonic process at Rex's factory in Hartola, Finland. Rex N-KineticTM hydrophobic polymers have been added to the composition as an additional flavor. They give Black Diamond E better anti-corrosion properties than previous chain lubricants and improve performance in severe cold conditions.
