Overview
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.

Get to know Dumonde Tech

There's more to Dumonde Tech than this one product. Our Dumonde Tech page has the full Dumonde Tech lineup we carry and more about the brand.
Visit the Dumonde Tech page →What is the difference between Original and Original Lite?
Original is more concentrated for maximum durability in the most demanding conditions. Original Lite is a lighter concentration of the same formula, suited for drier conditions and riders who prefer a lighter-feeling application.
Can I use Original Chain Lube in wet and rainy conditions?
Yes. The polymer bonding formula resists washout in water, making Original Chain Lube one of the better performing options for wet weather riding compared to conventional oils that rinse off quickly.
Is Dumonde Tech Original Chain Lube safe for dropper post cables and housing?
Yes. The formula is safe for use on cables, housing, and pivot points throughout the bike, and will not harm plastic or rubber components it comes into contact with.
