At Kogel Bearings, they believe ceramic bearings set the gold standard for bottom brackets, derailleur pulleys and wheel bearings. The ceramic material used, Silicon Nitride, is hard and wear resistant, and will not rust or oxidize. It can be precision machined into perfectly round balls with super tight tolerances and polished smoother than any metal, making it perfect for bicycle bearings.
- Ceramic bearings provide optimum drivetrain efficiency.
- Precision machined components ensure a smooth, squeak-free ride.
- Bomb-proof, all-weather seals to keep you riding no matter what.
- ROTOR 24mm
- SRAM GXP
This item is shipped with a separate GXP washer, meaning this bottom bracket will fit a Shimano, Sram GXP & Rotor 24mm crank on a BB30A frame.
BB30A is an asymmetric bottom bracket found on certain Cannondale frames: Synapse and CAAD12.
To install a Cannondale crankset on any of the above frames, choose a standard BB30 bearing set.
We recommend selecting all-weather seals, as these will withstand bad weather and any off-road cycling you might do. For your best bike, racing bike or fair weather bike, select the road seal for a marginal friction saving.
