Ceramic Grease represents Finish Line's most advanced bearing lubrication technology. Formulated with ceramic particles, fluoropolymer additives, and premium non-toxic synthetic oils. Guaranteed to optimize the performance and efficiency of bottom bracket, hub, and headset bearings. As bearings become coated with ceramic particles, friction and heat are dissipated. Bearings last longer and run quieter and smoother. Prevents rusting even when exposed to salt water! Excellent on ceramic bearings, stems, and posts as well as cables and threaded assemblies.
