"What Our Gearhead® Experts Are Saying: ""I’ve used this on mountain and gravel bikes where conditions are rough, and it flat-out lasts longer than most lubes. Once it’s ridden in, the drivetrain stays quiet and clean, and I’m reapplying way less often. The key is using it sparingly and letting it bond—it really works."" We rely on Tech Original Bicycle Chain Lube when rides get gritty and conditions refuse to cooperate. Designed by Dumonde Tech for demanding environments, this lube goes beyond surface lubrication by forming a bonded, low-friction plating on chain surfaces. Once ridden in, it quiets the drivetrain, improves efficiency, and keeps components running smoother for longer stretches between applications. The polymerizing formula doesn’t wash off in wet conditions and actively resists grime buildup, helping chains and drivetrain parts last longer. Applied sparingly, it works its way into rollers and pins, then wipes clean on the outside so dirt has less to cling to. From cold-weather rides to muddy trail days, it’s a dependable choice for riders who want durability without constant maintenance."

Look in any pro mechanic’s tool box, and you’ll find a bottle of Dumonde Tech Original Chain Lube. It’s a bit more viscous than the commonly-used Dumonde Tech Light, but we’ve found it holds up a bit better to bad weather and gritty conditions.
