Eben Weiss, Bike Snob NYC Dumonde Tech is easily the best chain lube I’ve ever used. Drivetrains run cleaner and quieter for longer. …this is top-shelf stuff and your bike deserves it.

Fun fact: Before using Dumonde Tech, we would go through two cassettes and 2-3 chains + chainrings each a year. However, once we started using Dumonde Tech, we can get through the entire season on the same cassette and only replace our chain and chainring once a season.

Product durability is super important to me. I've been using Dumonde Tech lube since my first Tour Divide in 2007. 50 ultra events and countless miles later, it's still what I use. The freehub lube is also a favorite!"

In 2023, 1200km Paris-Brest-Paris, “I used Dumonde Tech chain lube, which kept the chain silent during the long ride without the need to reapply lube”.

After racing the 2023 Unbound XL Jan wrote: “At the finish, bikes were covered in mud, but our chains were still turning happily and quietly. They hadn’t even worn measurably during the 25-hour ordeal. We agree with Lael who recommended Dumonde Tech chain lube: “The only stuff that works.”

Racing El Reto del Quetzal in Guatemala, I used Dumonde Tech Classic Lite exclusively in the dry dusty conditions. My drive train was amazingly clean and quiet and I only re-lubed at the start of each stage. Great stuff, I love this lube!

Steven “GravyWheels” - Service Mngr, Marin Bikes “Marin Bikes demo fleet, proudly sports, for years; all Dumonde Tech exclusively…awesome products! The finest in the WORLD!”

Terry Duran, Norco “The improvement in shifting is noticeable.”

"In my 20 years in the bicycle industry, Dumonde Tech products have been regarded as the gold standard in lubricants and greases by nearly every mechanic I have worked with. The Lite chain lube lasts without attracting gunk and the Original lube holds up in the long, wet rides. Squeaky seal? Dumonde Tech. Freehub service? Dumonde Tech. You know a product is the best when manufacturers choose to use it on their own products - if it's good enough for Industry 9 and Campagnolo, it's good enough for me!"
