Dumonde Tech Original Bicycle Chain Lubrication

This is my favorite bike chain oil. It goes on clean, wipes off easily, works very well in dry conditions and is very acceptable in rainy weather. it doesn't collect dust and debris and lasts longer than other lubes. Yes, it needs to be applied more often it wet weather. It applies easily with minimal mess. If you clean the chain thoroughly before applying, almost no dirty rag at all.

I'm a longtime cyclist and have used countless chain lube products and strategies throughout my decades of riding... My current riding is 90% off-road these days in challenging conditions. - Late Spring through Early fall is the season of desert dust and Sierra Nevada Dusty Gravel that will coat you and everything you ride in chain-eating dust that makes your chain squeal loudly and adversely affect shifting ... - Winter is snow and cold and sand/salt on the roads With my other lubes (spray or drop-on drop by drop) I would only get anywhere from "less than one ride" (the "dry lube varieties) before the "chain squeak" would start and shifting would suffer, to a maximum 3-days with Teflon-wet lubes. Riding in the same conditions I am now at 2-weeks on just the original lube application and my shifting is still excellent, there is no chain noise at all and my bike and clothes have been coated with the chain eating dust I referenced. So this stuff is working! My drivetrain is 2x10 Shimano that is 6 months old so it already had a bit of wear but this lube has returned it to "brand new" shifting that is quiet and fast and reliable. Because my drivetrain was already in hard use, though I did keep the drive train clean and serviced and lubed, I didn't exactly follow the "directions" on the bottle of given by others who review this )though if the drivetrain were new I would use the recommended approach). I simply using soap and low-pressure hose water to clean the chain/drivetrain as usual. Dried it and ran it through a used rag I use for drivetrains to give is a light oil coating to prevent any rust. The next morning I came out and ran the pedals backward and was liberal with my application of this lube and wiped off the excess lube. I let it sit overnight and then once again ran the chain and jockey wheels through a fresh clean rag to get the remain extra lube off. Already I could tell there was less friction in the drive train just from this process. Loaded up and went for a 5-hour dusty desert ride... and I was amazed at the difference in drive train noise and shifting. After the ride, I did a quick visual on the quiet and perfectly-performing drivetrain and saw the accumulation of dust on the sides of the chain. Then just did a water-only rinse off of the bike, and dried it and used the same rag for getting the excess oil off the chain and jockey wheels. I the subsequent two weeks with many more dusty rides, I have repeated the water-only-rinse, dry the bike, and rag-wipe of chain and the derailleur jockey wheels and just go ride. I am waiting to see when it will start squeaking. So far I have logged over 200 miles off road in dusty conditions and I am still on the original application of lubricant without any squeaking or degradation of shifting. I know on the lube container directions (and on their website) they say to "wait until you hear the chain" until you reapply the lube, so I will, but in the meantime I am wonder how long I can get way with just the original application in these tough conditions. Of course your mileage may vary, but I am one happy camper with this product!

I've been using either this product or the Lite version for years. With any oil, important to clean the chain either before or after EVERY ride...but do that and your drive train ought to last for thousands of miles with only periodic chain replacement. Really like this product.

Love this lube. I had been going through different types of lube, trying to find one that worked well over a period of time (i.e. that I didn't have to apply every rider), and didn't really find one that I liked. This doesn't mean there aren't other great lubes around. I certainly haven't tried them all, and obviously some work better than others in various conditions. But I've tried a couple of wax lubes and some teflon ones and some regular old Finish Line, etc. This lube, for me, works the best and lasts the longest in the greatest variety of conditions. I haven't had to change lubes in wet conditions vs dry, and I apply one drop/link probably every 5-6 rides, but how often you'll need to apply really depends on how long your rides are. So individual results will vary. As others have stated, the way to apply this lube is ONE drop per link, right on the roller. Then run the chain through gears, and let it sit for a while. Then wipe the chain. I do still get some black buildup on the chain, the most after the first ride, but if you make sure you wipe the excess lube off, this will be limited, and is easily wiped off after a ride. AGAIN, I haven't used ALL lubes by any means, and I'm sure there are others that perform just as well for others that I either haven't tried, or simply didn't work as well for me. Hell, there may be a lube that would even work better for me, but this is currently the best I've found, and I don't really see a reason to keep looking. Good stuff.

I bike 160mi a week and have used many bike lubes. I purchased because Dumonde won several lube v lube contests in internet trials. Is it worth the price? Maybe. Am I any faster using it? Not measurably faster. However, it is the best smelling bike lube I've ever used! It makes my apartment and bike smell nice and it doesn't make a mess on my floor. Only 4/5 because it's more expensive that others that work just as well.

Was highly recommended to me by a friend who is a lifetime off-road mountain bike rider. Says it'll double the life of your chain. Sounds good to me and I just applied it to my new e-bike's chain.

I’m obsessive about regularly cleaning and maintaining my drive train for optimal performance. I’ve tried many chain lube brands and all of them did the job well, but Dumonde Tech is by far the best lube for any terrain. It just coats well for smooth shifting and silent pedaling for long multiple days of aggressive cycle touring. It does leave a slight residue which can be easily cleaned with a rag and isopropyl alcohol. I’ve bike packed multiple days in dry desert environments and surprisingly this lube does not attract sand or dust. I’ve cycled in torrential downpours in muggy wet environments for hours and this lube keeps my chain well coated from water and mud ingress. Overall a great option for anyone looking for a chain lube that lasts an exceptionally long time and protects your chain well. Dumonde Tech is highly recommended!

Been using this brand for a few years and while we don't ride bikes more than 10 times a year or so, have only had to oil chains once a year. Very happy with it.
