Hydrophobic coating for rex chain lubricants

Rex Race Day Spray is a unique product for treating your chain and cassette by yourself, for extremely low friction and maximal dirt repellency. Rex is an expert in fluorocarbon coatings and we have decades worth of expertise in manufacturing products for cross-country race skiing. Now, we are the first in the world to bring the same technology into cycling. Together with our chain lubes, Race Day Spray forms a lubrication solution with unmatched longevity and dirt repellency.

Race Day Spray works in conjunction with Black Diamond or Domestique chain oil. Race Day Spray significantly enhances the dirt-repelling properties of the chain oil and protects lubrication from contamination.
