I use the original formula, and have done so for several years. It was recommended to me years ago by a bike mechanic I trusted, and I have not been disappointed in its performance. The two recommendations for use that I would pass on are that I depend on the sound of the chain rather than its appearance to determine when to lubricate, and that I use soap and water to clean the chain rather than any solvent. I often have to wipe off excess for the first couple of rides after lubrication, but that may be user error. It isn't an issue at any rate.
I am a Machinist and lubricant technology is my main interest. These lubes (Lite, Original, Liquid Grease, Micro Resistance Grease) are unlike all the other types. They flow into micro clearances and stay viscous, amazing they don't dry out! They seem to have a self cleaning action to. So the reviews about wiping the chain off after a ride really does keep it clean. Of course I experiment on everything with these. Door hinges, locks, knife pivots, rusted tight threads, etc. This experimenting helps discover their properties and other uses. Great long lasting lubrication, and rust proofer, the best so far!
I use the original version of this lube more as it is one of the only lubes I have found to last more than a day or two in Portland rain. It is pretty thick yet doesn't get that dirty as long as you wipe off the excess after application. I generally use the lite on my road bike in the dry months as it is a bit cleaner. You can even mix the lite and original together to get whatever viscosity you want. I have tried pretty much every lube out there and this is my favorite.
I moved from using ProGold for years (which is a very quick, clean and easy solution for chain maintenance) to Dumonde as my preferred lube. It requires less cleaning, (i.e. chain does not get dirty) and seems to keep the links rolling smoothly for longer. Nothing is perfect, but this comes close !! I've been using the 'Lite' version for road and the thicker stuff for off-road, MTB and cyclocross. They are all too expensive for a bit of solvent and a few drops of oil, but hey.. a bottle lasts about a year, so it won't break the bank.
Lite formula works great in dry weather. Re-apply when chain becomes noisy, about 100 - 120 mi. or so. Don't over-lube, as over-lubed chain will collect grit and road grime. Re-apply after riding in the rain. After trying many lubes over the years, this one seems like the best balance of lubrication and not attracting contamination. This lube leaves a dark, protective coating, so don't over-do it. And I use an older-style oil that wipes off easily for pivot points in brakes and derailleurs. One bottle lasts me about a year of frequent riding when applied to the chain only.
I've been using D-tech on my road bike and bikepacking rig for several years. It holds to the chain really well and lasts. I carry a small bottle for trips when I expect dry, gritty conditions.
I've used a bunch of different lubes over the years. This is the best I've come across so far. The trick, after applying to a clean chain, is to wipe off the excess. This means wiping the chain with a good rag while spinning the crank. Do this for 2-3 minutes. After your first ride on the freshly lubed chain, wipe it again until you get a fairly dry cloth. Dumonde claims you don't have relube it until you hear the chain start to make noise. I relube it when the chain looks particularly dry. Also, I like the Dumonde Regular better than the Lite since it seems to adhere longer to the links in the Northwest rain. Even with Dumonde, there will be a little bit of crud building up on the links. I push a Q-tip through the big links. And, another trick to get some of the crud off: Use a smooth hand cleaner such as Gojo or Fast Orange and apply to a paper towel. Then run the sides of the chain through the daubed paper towel to do a partial cleaning of the chain. (A thorough cleaning necessitates taking the chain off the bicycle and soaking it in gasoline or citrus degreaser.) My wife's SRAM 8-speed chain lasted 4500 miles using the Dumonde Lube. I replaced the chain when the 1.0 mark fell into the links using the Park chain stretch tool. The chain does look cleaner with this lube. And I dont have to reapply the lube right away after riding 1 to 2 hours in a fair to middling rain, as I used to do with some other lubes.
I've been riding and racing for 35 years. I began using Dumonde Tech 12 years ago when I moved to the Seattle area, and I've never seen anything better. A dab on each link, spin the crank backwards for a minute or two, wipe the excess off thoroughly. The chain is quiet, smooth, and clean until you need to reapply. I've used the lite (yellow) lube for everything. Wet weather I might need to reapply every two or three days. Dry Weather, once a week. I've found the heavier (blue) lube to be overkill, and more likely to attract dirt.
It's really not a lube, but rather a dry plastic coating. I no longer get that black chain mark on my clothes or leg, when I get near my chain. You need to reapply when your chain rattles. Started with a sample from a show, and needed the bigger amount for all my bikes.Review Detail
Goes on easy. Solvent actually cleans the chain for you. After a simple wipe and roll of the crank and cogs you're done. Only drawback is the smell which reminds me of paint thinner and results in a headache but it quickly fades. Apply weekly for best results.
I swapped out ProLink Gold for the Dumonde light. Campy 11 drive went from noisy to silent and runs more smoothly. It is good stuff. One drop per link, spin it, and wipe the excess off and you are good for another 300 miles.
Began using the lite (yellow bottle) formulation with a new 11 sp. road chain about 700 mi. ago. Drive train shifts crisply, longer than with wax-based lube I was using. Also reapplication is needed less often, no more than every 100 mi. in dry weather for me. Chain stays cleaner than with my old lube, especially if I don't over-lube. It also doesn't smell as bad. Instructions say to reapply when the drive train gets noisy. If you're used to lubing after every ride or two, this will take some getting used to. But the chain definitely stays cleaner with less lube, and still runs well. I don't write many reviews. But wanted to share this one because this product will save you time and take care of your chain and cogs too. Keep on riding!
Recreational road cyclist riding is Seattle and Palm Desert. Especially in the desert, the chain oils just suck up grit off the road. This stuff is much better, easier to keep things clean. Also seems to quiet the chain down. The few times I have been caught in a good rain I encountered no problems
This is the most amazing chain lube I have used. For me, this is the only one I use, which is the Dumonde Lite. I feel that my bikes thank me. For me, there is no comparison to others on the market. This is definitely The One!
I used this on my road bike, commuter bike and my son's BMX bike. On my road bike it is obvious how much it quieted things down. Since a by product of friction is noise, it leads my to believe it is doing a good job. After several hundred miles it is still doing its job.
I have only used the Lite version for road biking in the dry. I have found that it lubricates very well and is fairly long lasting. The characteristic I really appreciate is how clean the chain wipes down with this product.
