Why Is Dumonde Tech Original Chain Lube a Go-To for Tough Conditions? Dumonde Tech Original Bicycle Chain Lube is not a conventional oil. It functions as a liquid polymer, bonding to chain surfaces through polymerization to form a long-lasting protective plating that conventional lubes simply cannot replicate. This molecular bonding keeps the chain lubricated and protected even under the punishment of mountain biking, cyclocross, and extreme weather conditions, where standard oils wash off and leave metal surfaces vulnerable to wear. The formula is also versatile beyond the chain, performing reliably on cables, pivot points, and seals, and it is safe for use on plastic and rubber components without causing degradation. Engineered with a minimal carbon footprint in mind, it resists washout in rain, lasts longer between applications, and extends the life of your entire drivetrain. Available in 2 fl oz and 4 fl oz sizes to suit all maintenance habits.
