A home mechanic's toolbox is not complete without a 16-notch, 44mm bottom bracket tool like Park Tool's BBT-9. A lot of parts on modern bikes use this interface, including Shimano, SRAM GXP, Chris King, Campagnolo and other bottom brackets, as well as all externally splined disc brake rotor lockrings. Additionally, the BBT-9 includes a tool that removes 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. Show more
