Our Classic LITE chain lube is a liquid plastic and through polymerization forms long-lasting plating on all chain surfaces. "Riding in" forms an extremely low-friction plating. Plating bonds to chain; can't be washed off! Components stay cleaner, last longer, and run quieter. Extremely durable and outlasts all other chain lubes! Environmentally sensitive and saves money. To be applied sparingly unlike many other lubes. Classic Lite and Original Bicycle Chain Lube (BCL) differ only in their concentration. Lite BCL is less concentrated for easier application and optimum performance. We recommend the Lite Bicycle Chain Lube for road bikes. You can confidently use Dumonde Tech's Bicycle Chain Lubes on all cables, pivots points, and seals. Safe on plastic, rubber and all seal materials. The product is designed to not harm your components. Eco-friendly and environmentally sensitive, our products are engineered to perform with minimal "carbon footprint" by not washing off in water, to use sparingly, lasts longer between applications, and your drive train lasts longer. Very good performer in extreme cold conditions.

- 100% bio-degradable - 100% plant-based - Coffee scented - Ride longer, cleaner, and more quietly

Our Classic Freehub Oil is a great addition for the bicycle market and another superior product from Dumonde Tech. Freehub Oil is the original lubricant on the market specifically designed for Pawl style freehubs which require a lightweight lubricant. Freehub Oil performs consistently throughout a wide temperature range. "Flow Point" is -40 degrees, is extremely low friction, providing the greatest protection. Simply follow the manufacturer's specification for the volume of oil required in your freehub body to experience the superior performance of Dumonde Tech's Freehub Oil. With Freehub Oil being lightweight, growing reports for other applications have been reported. It can be used as cable lube and brake lever lubricant for the small moving parts and the lightweight spring action they have. Time and cold temperatures do not affect the performance of Freehub Oil like with heavier viscosity, time and temperature aged greases. They become thicker and stickier as they age slowing down the parts action.

Our Classic Freehub Grease is specifically designed for all freehubs that require a lightweight grease. These style hubs we like to call the more mechanical hubs. Unlike the simpler, fewer parts of the Pawl style hubs. Dumonde Tech Freehub Grease performs in a broad temperature range from the heat of summer to the frigid temperatures of the north. "Pour Point" of Freehub Grease is -30 degrees. Follow the manufacturer's specification for the volume required in your freehub body to experience the superior performance of Dumonde Tech's Freehub Grease. Our Freehub Grease is Exclusively used by: Industry 9 "Legacy", "Hydra" and "101" hubs and Stan's NoTubes, Hermes Sport, and Hawk Racing. Used, endorsed and/or recommended by: Crank Brothers, Boyd Cycling, Ritchey Design and Paul Components. Campagnolo North America recommends our Freehub Grease as an alternative to their lb-100 Grease as it is no longer available in North America. Our Freehub Grease is a proven replacement for any hub or wheel company's grease.

Chill Zone™ is arguably the industry's most advanced rust-busting penetrating lubricant. It simply works like magic! Before giving up on a frozen crank bolt, a rusted derailleur spring, a seized seat post, or discarding your rusted chain, give Chill Zone™ a shot. Bike parts that normally need to be replaced can be reconditioned to ride another day. A special refrigerant propellant freezes metal to as low as -50°F/-45°C. This causes contraction of the metal and creates micro-cracks in the corrosion and galvanically fused metal parts. A penetrating release agent then breaks down and flushes out the rust. With Chill Zone, most seized parts regain full functionality.

Shock Oil is a semi-synthetic formulation that combines the best of available oils and additives for a super suspension oil.
