The Park Tool BBT-19.2 is compatible with some bottom brackets that feature a 16-notch tool fitting, including most Shimano® models with outboard bearings. Constructed from high-precision hardened chromoly steel, and can be driven using a wrench, socket, or 3/8" drive wrench.

NOTE: due to the shallow engagement of their tool fittings, the BBT-19.2 is not recommended for 16-notch disc brake rotor lockrings. Instead use the Park Tool BBT-9 or BBT-69.4.

Not designed for use with impact drivers or other power tools.
