Park Tool BBT-19.2 Bottom Bracket Tool

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

Also fits 16-notch Bafang® BBSH, BBS02 mid-drive e-bike motor lockrings.

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.
