What Our Gearhead® Experts Are Saying:"This grease has become my go-to for Hydra and DT Swiss-style internals. It’s light enough not to drag engagement, but sticky enough to stay put—especially important in the cold. It's way better than the oils most people default to."Smooth engagement and long-lasting hub health start with the right grease—and Dumonde Tech PRO X Freehub Grease is built to outperform standard lubricants in every condition. Designed for non-pawl and lightweight engagement systems, it uses Dumonde’s proprietary MRCC technology to reduce resistance and enhance durability, even in freezing temps and wet conditions. With a lightweight NLGI #1 rating, this grease stays exactly where it's needed—coating ratchet mechanisms and freehub internals without migrating away from contact surfaces like lighter oils often do. Whether you're dialing in a Hydra hub, prepping a winter fat bike, or servicing internal gear hubs like Shimano Nexus, PRO X Freehub Grease keeps the ride silent, smooth, and responsive from -30°F to summer heat.
