The people have spoken, and they're speaking about Dumonde Tech Bicycle Chain Lube. In fact, nearly ever person we've talked to who's used this product is a bona-fide fanatic. These newly converted spokespeople tell us BCL bonds better, runs cleaner and lasts longer than any other lube. And, its unique formula is environmentally friendly.

BCL works by building up "plating" on your chain, keeping it protected and smooth running. For best results clean and dry your drivetrain thoroughly before your first application. For reapplication simply clean with soap and water, not solvents or degreasers that will remove the "plating" base, prior to lubing.

Available in Light which we recommend for road bikes, or the more concentrated Original which we recommend for off-road or seriously abominable riding conditions.

*Ground Ship Only*

great stuff

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.

Good Stuff

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.

works well, chain stays cleaner than oil
by Anonymous

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

My favorite chain lube
by Spaghetti & Meatballs

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!

Once you start using this chain lube you stop using others even when they are right in front of you. Chain is noticeably quieter and performs better. Also, collects less material that needs to be cleaned up.

Lite Chain Lube Lasts Longer

I've been using the yellow Lite Chain Lube on my road bikes for about six months. It definitely lasts longer between lubes than other lubricants.

Dumonde Lite es Mejor!

I really like the The Lite lube. I ride a lot of not so clean roads and it doesnt pick up a lot of dirt. Just wipe the chain With a clean cloth, after you finish your ride! It is Amazing!

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.

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.

ATMO - the best chain lube
by RMc43
Competitive Racer
Seattle

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.

Great, and pretty clean lube
by fredbyte

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.

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.

Dumonde Tech Light chain lube
by Anonymous
Northern Central Valley

Just about every brand of chain lube claims to be the best. Haven't tried them all, not even close. Of the ones that I have tried this works as well as any, better than some. It lubricates well but with the common drawback as might be expected, It attracts dirt. Sorry, fortunately don't know how well it holds up in the wet.

Best road lube I've used lately.
by Dan STL, MO
Cycling Enthusiast

7 of 8 customers found this review helpful.

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!

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.
