PRAXIS M30 BOTTOM BRACKET TOOL 12 NOTCH PARK TOOL BBT-35-12

The Park Tool BBT-35-12 is a 12-notch bottom bracket tool designed to install and remove Praxis Works M30 bottom brackets, both threaded and thread-together, and the Praxis T47 Inboard. It is the dedicated tool for anyone fitting Praxis cranksets who wants precise engagement on the cups.

The body is CNC-machined aluminium, made in-house by Park Tool and anodized for instant identification. The 3/8" drive works with ratchets and torque wrenches to tighten the cups to the specified torque. The notches have a major diameter of 48-50 mm and a minor diameter of 46.3 mm. Integrated threads accept the BBT-RS retaining system, which uses adjustable spring tension to keep the tool fully engaged while you work.

Where to use the BBT-35-12 bottom bracket tool

• Threaded Praxis Works M30 bottom brackets

In everyday work it pays to clean the cup notches, grease the threads and screw the cups in by hand until they seat before final tightening with the torque wrench. With the BBT-RS fitted, the tool stays engaged even with the bike in the stand, reducing the risk of slips that mark aluminium cups.

The tool is not designed for impact drivers or other power tools. If you fit or service Praxis bottom brackets, the Park Tool BBT-35-12 bottom bracket tool is the dedicated tool you need on the bench.
