T47 uses 47mm inner diameter and uses the same bearings specifications as PF30, and install by thread. In essence, T47 is the same as PF30 and BB386, so it can be compatible with almost all crankset. T47 solve the tolerance issues of the press-in bottom brackets, and at the same time, it has the performance advantages of the 30mm shaft system. Of course, besides 30mm, we also offer the option for 24mm, GXP, M30 specification, to combine your bike and crankset.
