The Classic MR GREASE with our "Micro Resistance Polymer" technology provides the ultimate protection and performance for bearings and suspension forks. MR Grease polymerizes to the surfaces leaving a barrier of grease that reduces wear, provided corrosion protection, and is waterproof. MR Grease is carbon fiber safe. Our Classic Liquid Grease can be used to thin MR Grease to create a lighter weight viscosity if desired.
