Park Tool bottom bracket puller PT-BBT-135-12-

The BBT-135-12 Puller, made from precision machined 4140 steel, is a rugged tool designed for removing and installing select threaded bottom brackets with a 12-tooth tool mount, including the Praxis Works® M30 model.
The BBT-135-12 is designed to be compatible with any bottom bracket with the appropriate clamping element, with an extra deep body for extra wide axles and low-profile walls at the engagement point for recessed circlips.
The BBT-135-12 has three tool connections – a 3/8" drive, a 1" hex drive and a 36mm flathead wrench – allowing you to tackle even the most locked-up bottom bracket shells. For added stability, the BBT-135-12 features integrated threads for use with the Park Tool BBT-RS bottom bracket mounting system or GPS-1 guide pins.

It is suitable for 12-tooth threaded center-mount chucks with a larger diameter (outer side of the teeth) of 48–50 mm and a smaller diameter (inner side of the teeth) of 46.3 mm, including Praxis Works® M30.
