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.
30 LUBRICATIONS WITH ONE BOTTLE
UP TO 500 KM WITH ONE LUBRICATION
OPTIMIZED VISCOSITY FOR LONGEVITY
The unique elastic formula of Rex Chain Lube ensures optimal attachment to the chain without adding friction. Rex Chain Lube has been tested in road racing motorcycles at up to 300km/h speeds with good results.
When applying Rex Chain Lube, you will notice how the lube forms thin hair-like strings where the chain leaves the chainring or derailleur pulley. This happens before the lube penetrates into the chain, and it is normal behaviour.
CHAIN LUBE IN INDEPENDENT LABORATORY TESTING.
Wheel Energy laboratories is one of the few completely independent chain lube efficiency testing labs in the world. They were also an important partner in the extensive development process of Rex Black Diamond chain lube.
In a 300 km dynamometer test under 175 W magnetic resistance, Rex Black Diamond gave the best overall result, leaving competing high-end chain lubricants behind. The test protocol was designed by Wheel Energy, with no instructions or other input from Rex. In addition to lab tests, Black Diamond has proven its performance in Tour de France 2019 (1 stage win).
