Ride faster.

The Chris King PressFit 30mm Ceramic bottom bracket brings smoothness, reliability, and quality to PF30-equipped frames. Both cups house 24 ceramic balls in each cartridge—providing a measurable reduction in friction and weight when compared to steel. That means you’ll be riding faster. Bearings are user-serviceable with King's Grease Injection Tool (available separately). Just add fresh grease to purge the gunky, used grease and keep spinning. Racers can run thin grease or even oil on race day to minimize bearing drag and switch back to thicker grease for training to maximize the lifetime of your bearings.

  • 24 ceramic balls in each cartridge
  • Compatible with both 68 and 73mm PF30 frames
  • Works directly with BB30 of PF30 cranks
  • Conversion kit available for 24mm road, 24mm mountain, or 24/22mm mountain cranksets

All my bike noises gone

  • Familiarity: I've used it once or twice and have initial impressions

I replaced my 1-year old standard-fare plastic BB30 bottom bracket with this. Instantly, all my bike noises were gone. Including occasional pops and snaps I *thought* had been coming from the seat post. Of course, it's still brand new and so to be fair I will update this review later to confirm whether it stayed noise-free and hassle free over time. The aluminum bearing cups are said to avoid noises associated with conventional plastic PF30 bottom bracket platforms. I found the cranks to spin smoothly (as would be expected), but with slightly more resistance than the Kogel I just installed on my other bike. That difference in resistance is probably not significant in terms of watts, and the CK angular bearings are said to be more resistant to lateral loads than Kogel and other brands that have pure radial bearing designs, hence why I *expect* this to outlast the Kogel if I maintain them both properly. I have not tried the CK grease injector tool yet; I will purchase that later when it comes time to service these.

Unanswered Question

Hi,

Will the Chris King PF30 work with Wilier's EVO 386 bottom bracket?

I will use a Rotor 3D+ crank which has a 30mm spindle.



Thanks,

Frank

kind of like really nice underwear

  • Familiarity: I've put it through the wringer

Few people will know your bike has one of these, but you'll know, and that's what really matters. Easy to instal and like all King products, it's a timeless part that does what it does and even when you fear the worst (from neglect, conditions, and/or time) you'll discover it feels just as smooth as the day you installed it.
