Why We Like The ThreadFit T47-30x Bottom Bracket

Take your worn out old T47 bottom bracket up a notch with Chris King’s ThreadFit T47-30x Bottom Bracket. This silky-smooth BB combines King’s coveted angular contact bearings with the creak-free benefits of a threaded bottom bracket shell, and pairs them up with the 30mm spindle of your favorite crankset. T47’s shell finds a balance between the stiffness of a lofty PF30 shell, and the creak-free timelessness of a threaded bottom bracket. King’s angular contact bearings work for the long haul, wearing in, rather than out, so the bottom bracket only rolls faster and smoother over time. A grease port allows for simple servicing without taking it to the bike shop, with the help of a grease injection tool.
