This four-ounce bottle of Dumonde's Original polymer chain lube has a higher concentration of polymers than the Tech Lite. Because of the Original's concentration, it's designed for dirtier, wetter, more demanding environments. This lubricant is best suited for mountain biking, cyclocross, and gravel grinding. Dumonde Tech Original is also an excellent choice for e-bikes because of their increased torque and chain friction. Both the Lite and Original chain lubes are very water resistant because of their polymer (plastics) chemistry. Dumonde Tech chain lubes provide dry lube convenience with wet lube performance and durability.
