This synthetic oil is engineered to withstand the high friction temperature found on skateboard bearings and has a low viscosity. It has been specially developed by Bones to reduce friction and provides a durable microfilm for protection against corrosion. Bones Speed Cream is better for skateboards and longboards than Teflon based lubricants. It makes your bearings faster and longer lasting. Bones Speed Cream is suitable for the care of all commercial skate bearings. To clean your bearings before using Bones Speed Cream, we recommend the Bones Cleaning Tank.
