    Don’t break a sweat; use the BBT-9.

    This is Park's shop-quality tool for installing your Shimano 10-speed Hollowtech II bottom bracket cups. It's long enough to give you adequate leverage for installing the cups with the force you need. The precisely shaped metal teeth of the BBT-9 won't damage the teeth on your BB cups provided you use it with care. The small end of the BBT-9 has what looks like a plastic wheel on it. This is actually, the splined plastic tool that you'll need for the spindle bolt to preload the bearings on your Hollowtech crankset. Otherwise, the Park Tool BBT-9 is compatible with Shimano Hollowtech II, FSA Mega Exo, SRAM GXP, and most other external bearing bottom bracket cups.

    What you need for those CL rotors

    • Familiarity: I've put it through the wringer

    Should probably be sitting around in every bike rider's garage because at some point you're going to run into center lock rotors and you're going to need to replace them! I don't have much preference between this or another brand's Hollowtech BB tool but this one from Park has worked well for me!

    BB/Rotor Tool w/a Bonus

    • Familiarity: I've used it several times

    I use the Chris King BB tool for my threaded bottom bracket but it isn't deep enough to clear the end cap on my i9 superboost hub so picked up this BBT-9 to change out centerlock rotors. Another great tool and the shimano crank pre-load removal tool on the opposite end is a nice bonus.

    Great Versatility

    • Familiarity: I've used it several times

    Park Tools always delivers with quality, which is what I expected. Works for various BB cups, but I use the tool for installing & removing my DT Swiss centerlock brake rotor lockrings.

    great multi purpose tool.

    • Familiarity: I've used it several times

    this is a great quality tool that comes in handy quite a bit. it works for center lock rotors and threaded bottom brackets. I am glad that I own one.

    Great Tool

    • Familiarity: I've put it through the wringer

    This is a great tool designed to remove BB cups without any problems. It was easy to use, fitted perfectly and gave plenty of leverage to undo my bottom bracket. The new bottom bracket went in just as easy. Overall I would buy the same tool again, making removal and refitting of BB an easy job for anyone.
    Please keep in mind that this BBT-9 works with external bearing bottom brackets, including: Chris King, SRAM, Truvativ, Race Face , Chris King and Opens Cannondale Lefty forks

    you get everything you need

    • Familiarity: I've used it several times

    this tool is amazing, you two tools in one. so you will not be needing to purchase multiple tools. so pick this up so you can take off your bottom bracket!

    Great tool

      Unlike the Shimano version, this handy tool combines the BB cup tool AND the preload bolt tool. My friend with the Shimano version just lost her preload bolt tool and tried to use needle nose pliers, which marred the crap out of the soft plastic Shimano uses. Made me so glad I bought this one. Like most Park tools, it's well thought out, made well, durable, and a pleasure to use.
