Take the world class steels used in Super Reds and swap the steel balls for top quality grade 5, silicone nitride, hot, isostatic pressed ceramic balls and you have Bones Ceramic Reds.
 
These ones are lighter and provide faster acceleration because the balls weigh much less and they create less friction and are thus faster than Super REDS, with or without lubricant! Ceramic balls will not rust further lengthening their life.
 
Preferred by pros. Engineered for skating. Skate rated (not ABEC rated). 100% high purity silicon nitride ceramic balls. Removable high speed nylon ball cage. Removable non-contact, frictionless rubber shield. Lubricated with low viscosity Bones Speed Cream.
