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