Description
Bones took their classic Reds and Super Reds bearing design and turned it into a speed-machine with ceramic ball bearings and higher-quality steel races. Housed in hardened, chromium-steel casings and nylon retainers, the grade-5 ceramic balls spin effortlessly in the bearing. The isostatically-corrected, ceramic balls weigh less than steel, but are substantially denser, performing a ?self-correction? by essentially re-polishing the races after they?re worn. The technologically advanced ceramic used in these bearings takes Bones? world-reknown formula and enhances it for better impact absorption, speed, and durability.
