Ceramicspeed Ceramic Coated Bearing - 609 Info
The CeramicSpeed Ceramic Coated Bearing - 609 is a direct replacement bearing built for riders who want to recover watts that standard bearings quietly absorb. Silicon nitride ceramic balls run against hardened steel raceways — a pairing that reduces friction significantly compared to conventional all-steel bearings while lasting three to five times longer. The coated variant takes that further, applying a surface treatment to the raceways that cuts friction even more and adds an extra layer of resistance to wear.
A reinforced polymer cage holds the balls in consistent alignment throughout the bearing's service life, and CeramicSpeed's own grease — formulated specifically for these components — keeps things running at their best between services. Sealed against dirt and moisture, this bearing is designed to maintain consistent performance well beyond what you'd expect from a standard replacement.
