Finish Line(R) Ceramic Grease is engineered with ceramic particles, friction reducing additives, and premium non-toxic synthetic oils. It optimizes the performance and efficiency of your bottom bracket, hub, and headset bearings. As bearings become coated with ceramic particles, friction and heat are dissipated, causing bearings to last longer, and run smoother. Ceramic Grease is also fully waterproof and will prevent rusting, even in coastal climates.
