Chris King Ceramic Bottom Bracket (Road)
I don’t normally go for ceramic bottom bracket bearings (many are dubious longevity, e.g. months), but I could not resist the Chris King ceramic bottom bracket (about $135), with its 5 year warranty and user-serviceable niceties.
For that special race day, one can use the injector to put lighter grease into the bottom bracket bearings, or inject heavier grease for winter rain, or anything in-between.
While I don’t know if the drag matters, I could feel the difference with my fingers between the ceramic and steel versions.
The ceramic version maintenance is described this way:
The ceramic balls need only a small amount of a light weight premium synthetic waterproof grease for optimal performance.
Small grease additions more frequently works well to keep the bearing smooth and fast.
For longer greasing intervals or for abusive conditions, filling the bearing full of grease is recommended.
The Chris King Ceramic Bearing Bottom Bracket is identical in construction and compatibility to our stainless steel bearing bottom bracket.
All the Chris King qualities you love remain the same - Durability, Serviceability, Performance & Made in the USA. To this we've added ceramic balls, which are lighter, harder and with greater roundness than stainless balls, for a bearing with exceptional speed and strength.
Chris's bearing design allows us to use more rolling elements, or balls, than production-house bearings and we squeeze 24 into each bearing. More balls per bearing amplifies the greater strength of the individual ceramic ball and when built into our acclaimed stainless steel races make a foundation for smooth and strong pedaling.
The ceramic balls are harder and lighter which translates to faster movement with reduced friction. The combination of these factors when paired with our reliable sealing system allows us to use a very small amount of low-viscosity lube in the bearing meaning very little drag in the bearing. The result? You pedal with greater efficiency.
Partner this bottom bracket with our BB Injector Tool to quickly and easily repack your bearing grease and you have a high-performance bottom bracket that will last a long, long time.
