The Chris King ThreadFit T47 Bottom Bracket is a silky smooth, long-lasting bottom bracket built around angular contact bearings that wear in instead of out.
The 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.
The ThreadFit T47 is available in four variants and will fit 30mm, 24mm and 24mm stepped spindles.
ThreadFit T47 24i fits 86mm and 92mm shell widths with 24mm spindles.
Chris King bottom brackets utilize Fit Kits to ensure that cranks mate perfectly with Chris King's precision bearings, extend product life and reduce the potential for noise. Fit Kits will also allow you to use one bottom bracket with a wide array of cranks, if you happen to change your cranks in the future
