CeramicSpeed Ceramic Bearing - 6803 Info
The CeramicSpeed Ceramic Bearing - 6803 is the kind of upgrade that works silently — you stop losing watts to friction before you ever notice they were gone. Silicon nitride ceramic balls run against hardened steel raceways, delivering a surface hardness and smoothness that steel-on-steel simply can't match. A reinforced polymer cage holds the assembly together, while CeramicSpeed's own grease and precision seals keep contaminants out and performance consistent over time.
CeramicSpeed rates these bearings at three to five times the service life of standard bearings — a claim rooted in the inherent hardness and corrosion resistance of silicon nitride. The sealing design is worth noting too: keeping dirt and moisture out from the start means the bearing maintains its low-friction character across thousands of kilometres, not just the first few rides.
