Chris King ThreadFit™ T47 Bottom Bracket is the solution to bottom bracket noise
. A silky smooth, long-lasting bottom bracket built around our 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.
The ThreadFit™ T47 is available in four variants and will fit 30mm, 24mm and 24mm stepped spindles.
ThreadFit™ T47 30i will fit 68mm, 73mm, 83mm, 86mm, and 92mm shell widths with 30mm spindles, or 68mm and 73mm shell widths with 24mm and 24mm stepped spindles.
Installed well but initial "crank spin" was not as free as I expected. Two rides freed it up and super happy.
