Bottom brackets occasionally require removal for service, replacement, or upgrading. 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.
Fits 16-notch threaded bottom bracket tool fittings with a 44-45 mm major diameter (outside of notches) and 42.7 mm minor diameter (inside of notches), including:
- Shimano® BB80, BB5700, XT BB70, BB51, and previous external bearing threaded cups
- Campagnolo®
- SRAM®/Truvativ® GXP
- Chris King®
- FSA MegaExo®
- Hope®
- Race Face® X-type
- Surly®
- Wheels Manufacturing™
- Fulcrum®
Also fits 16-notch Bafang® BBSH, BBS02 mid-drive e-bike motor lockrings.
Features a 3/8" drive fitting and 1" wrench flats
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.
