Dumonde Tech Bike

Frequently Asked Questions

• What is Dumonde Tech’s polymer and MRCC technology and how does it protect my drivetrain?

  Dumonde Tech lubes use a liquid polymer that cures via friction, heat, and air into a microscopic, low‑friction plating on metal surfaces; Pro‑X products add MRCC (Micro Resistant Complex Compounds) for lower viscosity with high film strength that migrates to hot or high‑friction areas. The result is a waterproof, dust‑repellent barrier that improves shifting and reduces wear while remaining safe on seals, plastics, and rubbers. These formulas are non‑petroleum, low‑VOC, and designed for long service life without leaving sticky residues.
• Which Dumonde Tech lube or grease should I choose for road, gravel, and mountain conditions?

  For dry road riding choose Pro‑X Lite or Classic Lite for a thinner, clean‑running film; for gravel/mixed conditions Pro‑X Lite is a versatile option. For muddy, wet, or aggressive MTB use Pro‑X Regular (the higher‑film option) or Classic Original if you want a thicker, budget‑minded wet lube. Use Freehub grease for hub bodies and MR grease for bearings/bolts—both are formulated to pair with the Pro‑X lubes and are mixable when transitioning components.
• How should I apply Dumonde Tech chain lubes and how often do they need reapplying?

  Apply sparingly to each roller, backpedal to work the lube into the chain, then wipe excess and ride a few miles to let the polymer set; avoid heavy overapplication. In real‑world use these lubes often last hundreds of miles between applications (reports of 400+ miles in many conditions), but reapply sooner if shifting becomes noisy, performance drops, or the chain is heavily contaminated or submerged. Use MR grease for bearings and Freehub grease for hubs and follow manufacturer torque/assembly practices when servicing.
• Are Dumonde Tech lubes compatible with seals, plastics, and other greases or lubes?

  Yes, Dumonde Tech formulations are safe on plastics, rubber seals, and common seal materials, and their greases and lubes are designed to be mixable (for example MR grease can be used in combination with Pro‑X lubes). When changing between substantially different chemistries it’s best to clean components before switching and test a small area if you’re unsure. For sealed bearings, use the MR or Freehub greases specified for those applications to ensure correct film thickness and protection.
• How does Pro‑X Regular compare to Classic Bicycle Chain Lube and to wax/Teflon‑based lubes?

  Pro‑X Regular (with MRCC) delivers a lower‑viscosity, high‑film polymer that migrates to heat and friction points for exceptional durability and quiet shifting, making it better suited for racing, long rides, and wet or abrasive conditions. Classic BCL Original is thicker and works well as a cost‑effective wet‑weather option, while Classic Lite and Pro‑X Lite favor dry, road‑style conditions; compared with wax or Teflon‑based lubes, Pro‑X tends to leave a more robust polymer plating that resists washout and holds cleaner under heavy use. Choose Pro‑X for maximum longevity and performance, Classic for simpler wet/dry choices, and Lite variants for dry/road riding.
