What Our Gearhead(R) 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 -30degF to summer heat.
