Description

The Ceramic Upgrade You've Been Waiting For

The Chris King ThreadFit T47 Ceramic Bottom Bracket is a silky smooth, long-lasting bottom bracket built around angular contact bearings that wear in instead of out. ThreadFit™ T47 provides the security and reliability of a threaded bottom bracket with the stiffness and power transfer gains of a PressFit 30 bottom bracket shell.

T47 is a standard Chris King helped develop, an answer to the imprecise and often loud press fit bottom brackets that appeared on the market a few years ago. T47 offers the benefits of larger bottom bracket shells, mainly frame stiffness, with the upsides of traditional, threaded bottom brackets, precision and quietness.

You want this bottom bracket because it offers super low drag. You want this bottom bracket, because it can be opened, cleaned and repacked for years of faithful service.

Features:

  • King Lifetime Warranty
  • Legendary made-in-house bearings
  • Ceramic bearings
  • Threaded security with PressFit 30 shell stiffness
  • Engineered, manufactured and assembled in Portland, Oregon USA
  • A Fit Kit is required for use and included in the purchase price
  • Uses Chris King bottom bracket cup tool for installation
  • 24/30mm spindles
  • Internal or External bearings
  • Keep your bearings running smooth with regular service and Silver Grease.

Works exactly how it should

New frame needed a T47 internal BB. I was debating about doing a run of the mill, or splurging on the King. Glad I did. I don't have enough miles on this yet to say it's lasted 60,000 miles and has been trouble free, but I have others in other bikes going strong.

One thing to note. Ceramic bearings in our field of use aren't exactly all they're cracked up to be in terms of "making you faster". But, what I can tell you, is ceramic bearings last longer because from what I've found, they pulverize grit. My cross BB is going strong through 2 seasons of, well, cross weather. And I'm not delicate with the hose either, I blast the dirt out and call it a day.

So, I can say ceramic has a place for not getting so chunky and such like steel, but it's of course costly.

Regarding maintenance, it's not too bad, pop the seal ring out, flush with cleaner, new grease, pop seal back in, done. I do wish there was a cap or something over the seal itself like most BB's have, just for some added protection and a spot to put more grease, but it's not a big thing.

Threaded into the frame by hand too, and then I got the torque wrench to finish the job. No goofy threads.
