PF30 OSBB is the Specialized standard. The CeramicSpeed Shimano-compatible Bottom Bracket increases efficiency, durability, and reduces creaking. It also works with FSA and other 24mm diameter thru-axle cranks.
The kit consists of two cups with CeramicSpeed Bearings installed. There are two variants. Both Standard and Coated Bearings feature super smooth CeramicSpeed Balls and hardened-steel races. The Coated have an additional feature: a 3-micron thickmetallic layer over the races.
The layer further smoothes and hardens the steel, lowering drag and increasing life.
