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.

After decades of using the standard stuff, I found myself out of town and with limited options for lube. The local shop had this, I tried it, and fell in love. I use the green for everyday and dirty riding, and the yellow for bikes I know will stay clean. Lubes well, I definitely apply it less often than the other brands, and doesn't get too grimy or greasy. A little pricey, but the performance and that smell are well worth it.

I switched to Dumonde products on all of my bikes last year and haven't looked back. Green goes on anything that might get dirty or spend time in the wet, yellow on the dry bike. Lubes well, doesn't collect a lot of dirt, nice smell (yeah!), and cleans up nicely.

The chain moves very smoothly. There is some clean up needed after a ride on the frame under the chain, it's a little greasy & black.

A buddy told me about this chain oil...none better! They make several different lubes for several applications. Wippermann chains and DuMonde is the way to go!

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.

I'm not sure if it helps increase the longevity of the chain yet, however I was surprised at how much quieter my chain was after application.

I discovered Dumonde through their motorcycle chain lube but once I tried their bicycle lube, I'm blind to other lubes now. This is THE bicycle chain lube. It takes maybe 2 to 3 applications to fully coat a chain but once it's coated, it works like no other. Worth every dollar that you're going to spend on it. There are 8 bikes in my family, down from 9 just recently, and it takes me about 2 years to go through a 4 ounce bottle. Sure it costs more than Finish Line or Triflow, but it's the longest lasting and least maintenance lube I have ever come across. There's no need to look for anything else. It just works.

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'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 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.

Best road lube I've used lately.

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.
