Rex Black Diamond Chain Lube

ULTRASONICALLY TREATED IN REX R&D LAB

The secret of this new lube is the Black Diamond particles that are mixed into the lube in a time-consuming ultrasonication process at our factory’s Racing Service lab.

The Black Diamond particles significantly improve the properties of the lube: Lower friction, lower wear and increased rain resistance.

In continuous metal-to-metal contact that occurs in drivetrain while riding, the particles form an ultra-thin and hard layer that minimizes friction and wear, and is also waterproof

NEXT LEVEL COMBINATION OF DRY AND WET WEATHER PERFORMANCE

Previously, seeking for the lowest possible friction in a chain lube has meant sacrificing all-weather performance. So-called “wet” lubes have traditionally been very energy-stealing.

Rex Black Diamond combines test-winning friction levels with strong weather resistance in a previously unseen way. Black Diamond has been tested in demanding race conditions by our elite athlete team. The true king of chain lubes!


N-KINETIC™ WAX
FEATURING THE LATEST RACE SKI WAX TECHNOLOGY

They have upgraded the wax blend used in Black Diamond lube to the same Rex N-kinetic™ technology that is used in the best cross-country ski waxes. The slightly lower viscosity results into lower friction and better lube penetration into the chain. Rex is well known for its world cup level fluorinated ski waxes and is an expert in paraffin wax-based applications with six decades’ worth of experience.



WAX BASED
SOLVENT-FREE, NON-VAPORIZING, UNDILUTED

Adding solvent or water to a chain lube is generally thought to be a great way to reduce manufacturing cost and giving the manufacturer a better margin. At Rex, we think otherwise. Every drop you apply on the chain is 100% lubricant and not something that will evaporate into the air. Unlike with most chain lubes, there is no need to wait until the solvent evaporates before you can ride your bike.
