BB30 frames deserve bearings that match their stiffness advantage. Our BB30 Ceramic BB uses angular contact bearings with Grade 3 silicon nitride balls and DLC-coated races — the same geometry used in aerospace for handling both axial and radial loads. Press-fit into any BB30 shell (42mm ID, 68mm width) with integrated dust covers that keep debris out. Compatible with 30mm spindle cranks, with adapter sleeves included for 24mm cranks.
What You Get
- ✓ Angular contact geometry handles pedaling loads better than deep groove
- ✓ Grade 3 Si₃N₄ ceramic balls with DLC-coated races
- ✓ Integrated dust covers — not an afterthought
- ✓ Zero-tolerance press fit eliminates creak
- ✓ Works with 30mm AND 24mm cranks (adapters included)
- ✓ Designed for BB30 frames: Cannondale, Cervélo, etc.
