Description
Short product description
REX Black Diamond is a wax-based, ultra-long-lasting chain lubricant for efficient lubrication of your bike's drivetrain. It is designed to reduce friction, minimize wear on the chain and sprockets, and perform reliably in both dry and wet riding conditions. Black Diamond is well-suited for road, gravel, and mountain bikes when the goal is a quiet, efficient, and low-maintenance drivetrain.
REX Black Diamond chain lubricant for efficient and long-lasting chain lubrication
REX Black Diamond is a high-performance chain lubricant from the Finnish brand Rex, combining a wax-based formula with low friction and excellent durability in varying conditions. It has been developed for cyclists who want to keep their drivetrain as efficient as possible while reducing wear on the chain, sprockets, and derailleur components.
The Black Diamond formula creates a durable, low-friction lubricating film on the metal surfaces of the chain. This reduces metal-on-metal friction and helps keep the drivetrain responsive even on longer rides. The wax-based structure makes the lubricant particularly beneficial when long-lasting protection is required without constant re-lubrication.
The updated V2 formula contains more wax and utilizes the same technology as Rex's Black Diamond hot wax. Thanks to this, the chain lubricant works well with Rex's hot wax products and is also suitable for cyclists who want to combine the convenience of liquid lubrication with the performance of wax lubrication. The PFAS- and solvent-free formula makes this product a modern alternative to traditional chain oils.
REX Black Diamond is suitable for road cycling, gravel riding, commuting, and mountain biking. It is an especially good choice when you want your drivetrain to have low friction, a long service life, and reliable performance in both dry and wet weather.
