Chris King Press-Fit 24mm Ceramic $224.95
Smooth is an understatement.
While Chris King has always been revered for its steel ball bearings, there's no denying the fact that ceramics are lighter and offer a measurable reduction in friction. And, if quality and ultimate performance are your two bottom bracket requirements, look no further than this Press-Fit 24mm Ceramic bottom bracket.
Like its steel counterpart, the PressFit 24mm bottom bracket houses 24 ceramic ball bearings in each cartridge. More balls per bearing amplifies the strength of each individual ceramic ball. And, when built into King's acclaimed stainless-steel races, you've got a foundation for industry-leading strength and performance.
To ensure that reliability, the bearings King employs its extensive sealing system and made the bearings user-serviceable. All you need is the Grease Injection Tool (sold separately) to keep things spinning smoothly, simply add fresh grease with the tool in order to purge gunky, used grease. This system also has a fringe benefit for racers -- it provides the option to run thin grease, or even oil, on race day in order to minimize bearing drag. And, when you're not racing, it's a snap to inject thicker grease in order to maximize durability.
The Chris King PressFit 24mm Ceramic Bottom Bracket fits 24mm road cranks and 86.5mm bottom bracket shells, 24mm mountain cranks and 89.5mm, or 92mm bottom bracket shells, out of the box. 86.5mm shells and 24/22mm road cranks will require King's Conversion Kit #7, while 24/22mm mountain cranks and 89.5 or 92mm shells will need Conversion Kit #6. The bottom brackets are available in either Black or Red.
