WITH THE BEST RACE SKI WAX TECHNOLOGY
In addition to skiing, we at Rex are also passionate cyclists. This is the main reason why we developed the lube. We started playing with the idea “If Rex made a chain lubricant, what would it be like?”. That sounded so interesting we had to find out!
The Rex Chain Lube recipe combines out-of-the-box thinking with the best raw materials used in high-end fluorinated ski waxes. 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. Each batch of Rex Chain Lube is carefully hand-mixed at our factory in Hartola, Finland.
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.
ULTRA LOW FRICTION
DYNO TESTED AND OPTIMIZED FOR BEST LONGEVITY AND WATT SAVINGS
- In the Friction Facts tests, Rex lube was the 10th fastest out of 55 lubes ever tested, with 5.48 W average friction.
- Most of the more efficient lubes are either not chain lubes at all (olive oil, hard paraffin wax), or thin solvent-based lubes with much shorter reapplication intervals.
- Rex lube is the fastest solvent-free and non-vaporizing chain lube tested by Friction Facts. (tested 7/2015)
- In longevity tests done by Wheel Energy, Rex outperformed competing mineral oil and solvent-based lubricants with a significant margin.
COMBINING THE BEST PROPERTIES
OF DRY AND WET LUBES
Rex Chain Lube has been tested for two years in all possible summer and winter riding conditions, in road and MTB use. The lube combines the best properties of so-called dry and wet lubes, creating a true all-condition, all-year lube for all cyclists.
In dry road conditions, the lube performs well for up to 500 kilometers. In typical use, only wiping with a dry cloth is needed before reapplying the lube. Before using Rex Chain Lube for the first time, it is preferable to fully degrease the chain for best results. Best lubrication performance and longevity will be achieved after 3–4 applications, when the lube has completely penetrated into the chain.
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.

REX DOMESTIQUE FAQ:
THERE IS BLACK GUNK ON MY CHAIN AND CASSETTE, WHY?
To keep accumulation of wax residue at minimum, always wipe the chain with a cloth or tissue always before applying Rex Domestique again. This keeps the chain and cassette cleaner in continuous use. The dirt repellent additives of Rex Domestique push the dirt on the outer surface of the chain. Despite dirty appearance, the inside of the chain remains clean. You can prove this by twisting the chain with your hands. It won't sound and feel gritty. Applying too much lube will also make the drivetrain look messy. Apply one drop for each chain link.
THE LUBE WON'T COME OUT OF THE BOTTLE, WHY?
Apply Rex Domestique at room temperature. The lube is more fluid in warm temperature.
SHOULD I DEGREASE THE CHAIN BEFORE EACH APPLICATION?
We recommend degreasing with Rex Chain Cleaner and a chain cleaning device before you begin using Rex Domestique, to ensure that previously used lubricant won't affect its performance. When using Domestique regularly, only wiping with cloth is needed before reapplying the lube. A thorough cleaning is only needed after riding in extreme conditions.
MY CHAIN IS MAKING NOISE JUST AFTER 20 KM, WHAT IS THE PROBLEM?
The longevity of the lubrication is extremely dependant on the conditions. 500km with one lubrication can be easily achieved in dry summer conditions on a road bike, but the same distance in muddy MTB conditions can even wear your chainrings and cassette to bad condition, no matter which lubricant you use. In wet / dusty / muddy conditions you can protect the chain from contamination with Rex Race Day Spray hydrophobic coating. In wet conditions, Rex Black Diamond chain lube is also more durable than Domestique.
A domestique is a road bicycle racer who works for the benefit of his team and leader. In French, domestique translates as “servant”. The use of the term dates back to 1911, although such riders existed before then.
