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 allow 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.

Smooth, long lasting, and clean.

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.

Great, and pretty clean lube

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.

simply the best chain lubricant

No other lubricant works as well. This product goes on and stays on without attracting a lot of dirt. A bottle goes a long way, because it stays on the chain, no dripping and you can apply it sparingly. I have found no other chain lubricant that compares. Great for mountain, road and cross bikes.

Just trying it out, but so far so good!

Would have tried this long ago if not for the price. Only applied twice so far (but that's a good sign in a month, right?) and am still debating whether I buy their whole Only lube when you hear your chain? velosophy.

So far so good.

Great lube so far

Just switched to Dumonde Tech Original based on all the great reviews I saw online as well as from coworkers and LBS mechanics.

I live in the Seattle area and commute to work as well as ride my bike for general transportation. So far I am very impressed. I completely cleaned my drive train and let it dry overnight before applying. I wiped the excess and then let it sit another day before riding. I couldn't believe how quiet my drive train was. I have never heard it (or not heard it) that quiet. We had a big windstorm recently followed by heavy rains so our roads and bike lanes are covered in rotting leaves, pine needles and other debris. My bike is filthy but somehow my drive train still looks like I just cleaned it.

Dumonde is my Fav!

Dumonde DryLight is the best I have used.

Have tried too many to list but this one seems to provide excellent lube while not becoming a dirt magnet.

Use it for Road and Mountain Biking. Just need to reapply a bit more for Mountain but if your not cleaning your chain on a regular after ride basis then you are missing the point anyway

My favorite chain lube and a great buy.

I've been using Dumonde lube on my road bike for over a year. 3,500 miles. Great chain lube. I recently ordered a bottle from BTD and was surprised when I received it. I've been paying bike stores over [$] for a TWO ounce bottle. This is a FOUR ounce bottle. A great deal!!

Best chain lube I have ever used

Dumonde Tech Lite is the best chain Lube that I have ever used. I ride close to 7,000 road miles a year and I only oil the chain after i wash the bike or when the chain starts to squeak a bit, a 4 oz. bottle last me well over a year. The oil is clean and the chain doesn't get as gunked up as it does with other products i have used. Just put a drop in each link pivot point turn the crank a bit, wipe off any excess and you are good to go.

This the best chain lube I've tried so far. You don't need to apply too often. When the chain is a bit dirty I just use damp cloth wipe it off.

Reduces chain noise

I've only been using this oil for a month or so (600miles), so, can't speak to how well it protects the chain in the long run. However, the first thing I noticed was how quiet the drive train becomes after applying it. Hopefully that translates to reduced chain wear and tear. Also, love the bubble gum smell!

Just started using this product and am really pleased with my results

I degreased the chain as per the instructions, applied dumonde chain lube, wiped it dry and rode as usual. I really liked the way it lubed and didn't turn black and nasty on my chain, cassette, and chain rings. I now only reapply when the chain starts to make any noise. It's great.

Nice Stuff

I've been using this lube about six months now. It does last a long time, and with very little effort my chains always look clean and glossy. As warned, I took pains to make sure that the initial application was on a very clean chain I removed it and soaked it in solvent. After riding a new application there is a black residue that develops. However, that residue wipes off easily and wiping the chain after each of the first few rides was very easy (I simply run the chain through a papertowel a couple of times) and brought the chain back to a very clean state. Ditto the chainrings and cassette. It's much easier to keep the chain looking clean than with any other lube I've used. I'm getting between 300-400 noise free miles between applications! I've felt no need to completely clean the chain since, with the wiping between rides and reapplication after 300-400 miles, I always have a well running and clean chain. And I love the blue cheese smell.

Impressive lube

I have been very impressed with this lube. I have used tri-flow and finish line in the past and this lube puts both of them to shame. When applied properly, it stays put and does not spread to the cassette, chain rings or the derailleur, as the others are wont to do. It may be my imagination, but pedaling is quieter and shifting is better with less jumping and hesitation. It is more expensive, but well worth it, as bike maintenance is my job exclusively, in this family, and everything stays cleaner, longer! It definitely helps to apply, then let it sit overnight, and wipe off the excess the next day.

not only makes the chain quiet but makes it last 5 to 6 times longer

As most of the reviews have said this stuff keeps the chain quiet but the best suprise i got from this lube is how long my drive train lasts i get anywhere from 13k to 15k from a chain cassette combo which to me makes this lube pay for itself at well over 200 bucks for a dura ace chain and cassette on ebay this lube by my best quess saves me almost a thousand bucks on replacing those parts every 6 or 7 weeks at 2,500 miles for the year, seeing over the last 9 years i've cycled 111,334 miles or a little over 12,000 yearly so this stuff has saved me a small fortune in replacement parts and that alone makes this the best stuff ever made for your chain and your pocket book , only downside i can see is it is a little bit messy compared to other lubes but for what i save i'll clean more othen and do it gladly.......

Really quiets down chain noise (Regular)

I'm pretty OCD about my chain - wipe it off after each ride and cleanrelube every 300 miles or so. This is the best stuff I've found that really quiets chain noise. Put it on heavy, let sit overnite and wipe it off well.

Using this lube for a long time.

I have been using the Tech-Lite for more than 5 years now, it was recommended by the bike shop that I frequent. They have since stopped recommending it and carrying it because it is so hard to clean off of cassettes and derailleurs, and it is a wet lube and tends to attract dirt. It does work well and I have found that citrus cleaners dissolve it quite nicely and I don't mind spending a few extra minutes cleaning it from my drive train occasionally, and reapplying the lube.

Superb product with one exception

Excellent product. Durable (especially in wet conditions). The only exception I've run into is very dusty conditions. After carefully following instructions (the chain was spotless prior to applying), I get a build up of sludge after the first several rides. Dry cleaning your chain with a rag after the first 3-4 dusty rides is very helpful. After this, no problem with dust. I have the same problem with the Lite version of Dumonde Tech.

Excellent, quited down my Dura-Ace drivetrain.

Long back, I tried wax based lubes but they made an awful mess. I returned to Tri-Flow even though it required frequent applications and chain cleaning. Now that I've tried the Dumonde Tech lube (I use the lighter version) I must say I am very pleased. It stays much dryer than Tri-Flow and holds a lot less dirt. But my main hurrah for this product is how much it quited down my previously noisy Dura-Ace drivetrain.

Great light lube

I use the lightweight version on my race bikes' chains and on the internals of my PowerCranks. I'm not super-thorough about cleaning and re-lubing, and this stuff seems to hold up pretty well.

I've bought the heavier version for my rain bike, but I haven't tried it out yet.

Great chain lube.

I've used the yellow Dumonde Lite for years and re-lube every 3-4 rides depending on weather and mileage. I drip it on then wipe it off and it keeps the chain clean as well. My mechanic always remarks what great shape my chain is in and how long they seem to last, usually 2000-2500 miles. Only drawback is the fumes which are strong. I think best used well ventilated.

Great Lube That Quiets Drive Train Noise

I tried this lube simply because I had read and heard that it reduces noise from the drive train. My old lube worked well as a lube but the Dura Ace 10 drive train was pretty noisy with it, much more so than I thought such a quality component should be.

This stuff works as well as I had hoped. I started with Dumonde Lite when I changed to a new chain. It was immediately quieter than the old lube by a noticeable degree and got better until about the third oiling. Instead of the low grinding noise I previously heard while pedaling along now, it is more of a subtle hum.

I have tried a number of different lubes over the years including wax lubes (hate them), oil based lubes and synthetic lubes. Except for the wax lubes they were all kind of serviceable as lubricants but this one works well both as a lubricant and a drive train noise dampener. It quiets the drivetrain noise much better than anything I have tried. I like it a lot and won't go back to the old lubes. We have now switched to Dumonde Lite for all four road bikes that my wife and I own.

I highly recommend it for road bike use.

The best lube there is.

I have been using Dumonde for about 8 years. I have never found a better lube. This stuff keeps the chain quiet and shifting regardless of conditions. Stream crossings and rain do not wash it off. Cleaning your bike with soap and water will not remove the lube.

I use the original on both mountain and road bikes. The key is to clean your chain as recommended, coat every link, ride a bit, then wipe off everything, chain and chain rings. Once a base is established, this stuff lasts. I find that I re-apply about every 300 miles, rain or dry.

This stuff is for real !

I received this as a gift from my sister in law last Christmas. My brother and her being competitive racerriders in Southern California I thought this lube would not hold up in the Pacific Northwest. I was thinking this stuff is desert lube and it would wash away after one puddle! I was so wrong, this stuff is as advertise, sticks to the chain in all conditions and some of the cleanest lube I have ever used. Cross and MTB for me and after riding through what would have other lubes buckling and your drive train sounding like a nest of squealing sparrows this stuff is still going strong, quit as ever. I seriously think this is alien technology, but whatever it is I am hooked and I hope she gets me more this Christmas.
