CeramicSpeed PF30 Bottom Bracket

This bottom bracket is specifically designed for frames with a PF30 standard, which features a 46mm shell diameter and a 68mm shell width. Please verify your frame's bottom bracket shell specifications before purchasing to ensure compatibility.

Yes, this bottom bracket is engineered to adapt PF30 frames to accept 24mm thru-axle cranksets, including Shimano Hollowtech II and other compatible 24mm spindle cranks.

The unit features extended inner sleeves that join in the center. This integrated design creates a more stable, unified structure that minimizes the movement often responsible for persistent creaking in press-fit systems.

Yes, the bearings are fully serviceable. You can clean and re-grease them to maintain performance and extend the lifespan of the unit, rather than needing to replace the entire bottom bracket when maintenance is required.

Yes, by utilizing high-grade ceramic balls paired with hardened-steel races, this system significantly reduces frictional drag—up to 75% less than standard steel bearings—which translates to a more efficient drivetrain.

Yes, the integrated sleeve design serves a dual purpose: it stabilizes the bottom bracket and acts as a protective barrier, preventing internal cables from rubbing against the rotating crank spindle.
