CeramicSpeed BB30 Bottom Bracket - BB30

Performance & Use Case
The CeramicSpeed BB30 Bottom Bracket is the premium upgrade for any BB30 press-fit frameset. CeramicSpeed's hand-built ceramic bearings deliver near-frictionless rotation and exceptional longevity - the bottom bracket sits at the heart of the drivetrain and a small improvement in friction compounds across every pedal stroke. For SRAM AXS and Shimano road owners chasing efficiency, it is the upgrade that transforms drivetrain feel.

Construction & Materials
Each unit features hand-built bearings carrying the load from crank to frame, housed in precision-engineered cups with integrated dust covers. The contamination-resistant design prolongs bearing life under road conditions. Coated bearing variants gain CeramicSpeed's 3-micron metallic surface treatment - races harder than steel, with 60% longer life and 50% lower friction than uncoated alternatives.

Compatibility
Fits any BB30 press-fit frameset - 42mm bore, 68mm shell width. Two spindle-compatibility options cover Shimano Hollowtech II (24mm) and SRAM DUB (28.99mm) cranksets. Coated bearing option offered for the Shimano variant. Select the variant that matches your crankset and your service preference. Each unit includes mounting cups, dust covers, spacers, CeramicSpeed All Round Grease and sticker sheet.
