Rex Black Diamond E-Bike Chain Lube

Rex supreme performance chain lube in dry and wet conditions. Rex Black Diamond has been thoroughly tested in independent testing laboratories on two continents. In tests conducted by Zero Friction Cycling (Australia) and Wheel Energy (Finland), Black Diamond was tested to be the longest lasting chain lube ever, and also one of the lowest friction chain lubricants.

Rex took the recipe for Black Diamond -lube and made it even better for electric bikes in two ways: Nanotungsten(WS2) improves the pressure resistance of the lubricant and further reduces the level of friction. When used in combination with our proprietary Black Diamond nanoparticle technology, a synergistic effect is achieved. The use of both additives at their optimal concentration gives a result that is better than the sum of its parts. For best performance, both nano additives are blended into the lubricant in an ultrasonic process at the Rex factory in Hartola, Finland. As an additional spice, they added Rex N-Kinetic™ hydrophobic polymers to the composition. That gives Black Diamond E better anti-corrosion properties than previous chain lubes, and improve performance in very cold conditions.
