Finish Line Premium Grease is Super Slick and made with Teflon fluoropolymers. This 100% synthetic oil grease coats ball bearings and races, preventing wear and distortion in headsets and bottom brackets, even in brutal down hill racing and over extended periods of time. The slickest, toughest bicycle grease available. No matter how hard or long you ride, Finish Line Premium Grease will provide the lubrication your bearings require. New “functional” thickener totally prevents rust and corrosion (even in saltwater).
