Dumonde Tech lubes have gone from a cult following to the mainstream via the mechanics and shops that swear by it. Only a small amount per link is needed to provide long lasting lubrication that quiets the chain and extends the life of drivetrain components. Best of all, it quiets and lubricates without being oily or greasy, and repels water. This original weight formula is recommended for tough conditions, wet weather, cyclocross and mountain biking. Many touring and long distance road cyclists prefer it as well, but for most road cycling Dumonde recommends the Lite version.

Dumonde Tech Original Chain Lube is a polymer-based liquid plastic that forms a thin, extremely low-friction coating on the chain. It actually bonds to the chain and can't be washed off with water and only minimally sheds while riding. This lubricant helps components stay cleaner, last longe, shift better and run more quietly. It is extremely durable and outlasts most other chain lubes while being environmentally friendly. Some reviewers have remarked on a impressive improvement in shifting performance with mis-matched drivetrains. Is it true? Hard to say, but we do trust anecdotal experience from serious cyclists and mechanics.

Original Bicycle Chain Lube (BCL) is the same product as the Lite version, which differs only in concentration and color. Original is recommended for cyclocross, mountain biking or road biking in wet conditions because the stronger concentration holds up to extreme conditions with ease. Once you apply and bond the lube, it lasts much longer than any other product we have used. When you start to hear the drivetrain making a little more noise than usual, just wipe off with soapy water, rinse, let dry, and reapply with very small drops. You will be surprised how little you actually need. Ride after applying, as heat best distributes and sets the lubricant. After your ride, just wipe off the outside plates of your chain to remove any excess.

You can confidently use Dumonde Tech's Bicycle Chain Lubes on all cables, pivots points and seals. It is safe on plastic, rubber and all seal materials. Dumonde Tech products are eco-friendly and environmentally sensitive. You can be sensitive to the natural world while still enjoying the benefits of this exceptional lubricant.
