Chris King bottom brackets utilize Fit Kits to ensure that cranks mate perfectly with our precision bearings, extend product life, and reduce the potential for noise. Fit Kits will also allow you to use one bottom bracket with a wide array of cranks, if you happen to change you cranks in the future.

Description
The two machined aluminum cups thread together ensuring the bottom bracket remains stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement.
Specifically designed for installing 24.00mm spindle diameter cranks (Shimano, Etc.) in Cannondale BB30A (42mm ID, 73mm wide asymmetrical BB shell) frames without the need for any adapters.
**Note: FSA MegaExo spindles can be between 24.00mm and 24.07mm in diameter. If your FSA spindle is 24.07mm, this BB will not work! Please purchase our FSA 24.07x37 ceramic hybrid bearings separately.**

Chris King CERAMIC Road Bottom Bracket Shim/Xtype/FSA (use mtb BB for FSA road Lite cranks ) 24mm spindle
The construction and compatibility of this Chris King® Ceramic Bearing Bottom Bracket are identical to the Chris King® stainless steel bearing bottom bracket. However, this bottom bracket uses ceramic balls, which are lighter, harder and have greater roundness than stainless steel balls, resulting in a bearing with less friction and exceptional speed and strength.
These factors along with Chris King's sealing system mean you need only use a very small amount of low-viscosity lube in the bearing. This means less drag in the bearing, allowing you to pedal with greater efficiency.
•Designed for Shimano™-compatible external type crank systems including Shimano™ Hollowtech II™, Race Face X-Type™, and FSA MegaExo™
•24 ball bearings per side
• Fully user-serviceable bearings
