Bones Swiss Ceramics

Bones Swiss Labyrinth Ceramics are in a class by themselves. If you want the best there is, this is it. The highly polished Cerbec ceramic balls, made from pure silicon nitride, are lighter, harder (resist pitting better), water proof, roll faster and last longer than the finest steel balls. Removable non-contact rubber shield resists dirt and moisture better and allows for easy cleaning and less rolling resistance. High speed Nylon ball retainer provides added speed and strength, increasing speed by 4MPH. Skate Rated clearances, tolerances, materials and lubricant provide the best performance and durability possible.
