T47 framesets

The T47 frames are threaded and come in 3 different widths: T47 with internal or external bearings, T47A (asymmetric). They are found on Trek and Factor bikes. A 30mm crankset is a good choice with this standard, but it is also possible to fit Shimano 24mm cranksets and Sram GXP or DUB cranksets.

-T47 external: 68mm wide frame

-T47A (asymmetric): 77mm wide frame

-T47 internal: 85.5 to 86.5mm wide frame

Choose your T47 ceramic bottom bracket based on the width and type of crankset you want to install. Some bottom brackets with identical compatibility are available from both Rotor and CyclingCeramic.

T47 BB: T47 internal, external, T47A bottom brackets for your Trek or Factor bicycle
