Dumonde Tech Original Bicycle Chain Lube The lube that will bond, not just coat. Dumonde Tech Original Bicycle Chain Lube is a liquid plastic chain lube that works through polymerization, forming a long-lasting, extremely low-friction plating directly on all chain surfaces. Unlike conventional lubes that sit on top of the chain and wash away, the Original formula bonds to the chain so it can't be washed off, keeping components cleaner, quieter, and running longer between applications. More concentrated than the Dumonde Tech Lite formula, Original is the recommended choice for mountain biking, cyclocross, and demanding conditions where longevity in challenging weather matters most. Safe on plastic, rubber, cables, pivot points, and all seal materials.
