A ceramic version of the super-popular Sabre's Built-In Labyrinth Bearings! Black ceramic balls are harder than regular Chrome Steel, which means that they need a lot less maintenance. In practice this means that your bearings will roll faster! Like the regular Sabre Built In Labyrinth's, they have all of advantages of built-in bearings over regular skate bearings. If, like most longboarders, you swap your wheels over regularly, you'll really appreciate the built-in spacers and speed rings - there's just less stuff to loose! They do last better if you slide a lot too, due to the spacers holding the bearings in better alignment. They also share the same killer combo of a Built-In Spacer and a Labyrinth Shield . Not only that, but they only have a bearing shield on the outside - making them super easy to clean as you don't really need to take the shields off for a quick lube. So this bearing has the easy clean of Bones Reds, built-in spacer like a Zealous Ceramic, and a Labyrinth shield like a Bronson G3 - all at a bargain price. We also stock Sabre's own bearing lube for when you do eventually need to clean them.
