Finish Line's Ceramic Grease is their most advanced bearing lubrication technology. Formulated with sub-micron ceramic particles, Teflon fluoropolymer and premium non-toxic synthetic oils, it's guaranteed to optimize the performance and efficiency of bottom brackets, hubs and headset bearings. As bearings become coated with the Teflon and ceramic particles, friction and heat is dissipated. Bearings last longer and run quieter and smoother. And, it prevents rusting even when parts are exposed to salt water, and is excellent on stems, seatposts cables and threads, too.
