CeramicSpeed 6803 Full Ball Ceramic Bearing Info
A standard steel bearing is the weakest link in any drivetrain or hub — the CeramicSpeed 6803 Full Ball Ceramic Bearing removes that link entirely. Built with a full complement of silicon nitride ceramic balls and no steel retainer cage, it runs ball-against-ball for maximum rolling contact and measurably lower friction than a conventional caged bearing. Ceramic balls are harder and smoother than steel, and they resist moisture and contamination in a way that steel simply cannot match.
The 6803 dimensions — 17 mm inner diameter, 26 mm outer diameter, 5 mm wide — make this a direct-fit replacement across a range of hub and bottom bracket applications. If you're replacing a worn bearing, this is the version that will outlast whatever came stock.
