Park Tool Bottom Bracket and Lockring Tool (BBT-9)

Bicycle bottom brackets require removal for servicing, replacement and upgrades. The Park Tool BBT-9 is used to remove and install select threaded bottom brackets with 16-notch tool fittings, including Shimano, SRAM GXP, Chris King, Campagnolo, and many others. This tool fitting is also found on some disc brake rotor lockrings. 

Additionally, the BBT-9 includes a tool for removal and installation of 8-point Shimano Hollowtech II crank arm adjusting caps. The long, plated-steel handle offers good leverage for high-torque applications and is vinyl-dipped for comfort.
