Rex Black Diamond Hot Melt Chain Wax Additive

Black Diamond Additive is an add-on for the black diamond hot wax chain lube. We transformed the already thoroughly tested and effective Black Diamond additive technology onto a solid Rex wax base. To ensure high manufacturing quality, we put all the Black Diamond additives into one black piece, which is hand-cast in our product development laboratory in Hartola. The black additive piece can be thought of as a bottle of Black Diamond chain lube in solid form! To make a more concentrated mixture add 4 white blocks to 1 black block for the longest-lasting, lowest friction bike lube in the world.
