Noisy drag in your freehub is not only irritating to listen to, but it also can suck the speed right out of your ride. The best way to zap your ride back into its old quick-rolling self is with a generous slathering of Dumonde's Pro-X Freehub Grease. This freehub grease is dsigned to work with freehubs that require lightweight grease, but more lasting lubrication than your light oil can provide. It's created with Dumonde's Micro Resistant Complex Compounds, or MRCC, to provide superior lubrication and friction reduction, while maintaining a light viscosity. Unlike some other greases that can get a bit gummy when the temperatures drop, Pro-X Freehub Grease has been built to withstand plummeting mercury with smooth rolling performance all the way down to -30 degrees F, which makes it the ideal grease for those looking to embark on snowy fat-bike adventures. Pro-X Freehub Grease is ideal for hubs that share lubrication between the freehub and wheel bearings, and Dumonde recommends that you follow your freehub manufacturer's specifications so you can be sure to dial in the perfect volume required to get your freehub rolling as smooth as butter.
