Lube Less, Ride Longer

Talk about cult followings — Dumonde Tech Bicycle Chain Lube (BCL) has it like no other lube we've ever carried. According to virtually anyone who's ever tried it, BCL will keep your drivetrain components cleaner, lets them last longer, and allows them to run quieter than what you'd get from any other lubricant out there.

BCL forms a long-lasting coat on all chain surfaces. As you ride, it forms a low-friction plating which bonds to the chain and can't be washed off. It's environmentally sensitive and it's extremely durable, as one ounce should provide roughly 10 applications.

To get the best results from BCL, first clean your chain and dry it thoroughly prior to the first application. This effectively primes the surface for the "plating" effect that makes BCL so successful.

For the first application, we recommend putting one drop on each link to really aid the plating effect, wiping the excess from the chain after it has had time to work itself into the pins. When reapplying, do so only by listening to your chain, not by its appearance. Use soap and water to clean the chain prior to reapplication — strong solvents and degreasers will remove the protective plastic plating from the chain, putting you back at square one. Allow three applications to achieve optimum plastic plating.

Dumonde Tech offers two versions of their BCL, the Lite (which we recommend for road bikes) and the Original (which we recommend for mountain bikes or for when you're readying for Paris-Roubaix). The Original is more concentrated than the Lite and excels in the most challenging conditions. The two BCL formulas are compatible and may be used interchangeably.

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.

After cleaning my bike chain, I put this lubricant on it and the chain seems to run smoother over the gears with less noise.

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.

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.

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.

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.

Revolutionary lubricant
rating
by DQ

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.
