Chris King Silver 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
